-## Fix `submit-coverage` CI failure
+## Unenforced coding conventions
+
+A few of our coding conventions are not yet enforced by the linter/auto-formatter. Be careful to follow these conventions in your PR's.
+
+1.  Unused anonymous function parameters should be named with an underscore + number (e.g \_1, \_2, etc...)
+1.  There should be a new-line between methods in a class and between test cases.
+1.  If a string literal has the same value in two or more places, it should be a single constant referenced in both places.
+1.  Do not import from a project's `index.ts` (e.g import { Token } from '../src';). Always import from the source file itself.
+1.  Generic error variables should be named `err` instead of `e` or `error`.
+1.  If you _must_ cast a variable to any - try to type it back as fast as possible. (e.g., `const cw = ((zeroEx as any)._contractWrappers as ContractWrappers);`). This ensures subsequent code is type-safe.
+1.  Our enum conventions coincide with the recommended Typescript conventions, using capitalized keys, and all-caps snake-case values. Eg `GetStats = 'GET_STATS'`
+1.  All public, exported methods/functions/classes must have associated Javadoc-style comments.
+
+### Fix `submit-coverage` CI failure
 
 If you simply fork the repo and then create a PR from it, your PR will fail the `submit-coverage` check on CI. This is because the 0x CircleCI configuration sets the `COVERALLS_REPO_TOKEN` environment variable to the token for `0xProject/0x-monorepo`, but when running the check against your fork the token needs to match your repo's name `your-username/0x-monorepo`.

+# Contracts testing options
+
+## Revert stack traces
+
+If you want to see helpful stack traces (incl. line number, code snippet) for smart contract reverts, run the tests with:
+
+```
+yarn test:trace
+```
+
+**Note:** This currently slows down the test runs and is therefore not enabled by default.
+
+## Backing Ethereum node
+
+By default, our tests run against an in-process [Ganache](https://github.com/trufflesuite/ganache-core) instance. In order to run the tests against [Geth](https://github.com/ethereum/go-ethereum), first follow the instructions in the README for the devnet package to start the devnet Geth node. Then run:
+
+```bash
+TEST_PROVIDER=geth yarn test
+```
+
+## Code coverage
+
+In order to see the Solidity code coverage output generated by `@0x/sol-cov`, run:
+
+```
+yarn test:coverage
+```
+
+## Gas profiler
+
+In order to profile the gas costs for a specific smart contract call/transaction, you can run the tests in `profiler` mode.
+
+**Note:** Traces emitted by ganache have incorrect gas costs so we recommend using Geth for profiling.
+
+```
+TEST_PROVIDER=geth yarn test:profiler
+```
+
+You'll see a warning that you need to explicitly enable and disable the profiler before and after the block of code you want to profile.
+
+```typescript
+import { profiler } from './utils/profiler';
+profiler.start();
+// Some call to a smart contract
+profiler.stop();
+```
+
+Without explicitly starting and stopping the profiler, the profiler output will be too busy, and therefore unusable.

+## Contract examples
+
+Example smart contracts that interact with 0x protocol.
+
+## Usage
+
+Contracts can be found in the [contracts](./contracts) directory.
+This package contains example implementations of contracts that interact with the protocol but are _not_ intended for use in production. Examples include [filter](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/v2-specification.md#filter-contracts) contracts, a [Wallet](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/v2-specification.md#wallet) contract, and a [Validator](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/v2-specification.md#validator) contract, among others.
+
+## Contributing
+
+We strongly recommend that the community help us make improvements and determine the future direction of the protocol. To report bugs within this package, please create an issue in this repository.
+
+For proposals regarding the 0x protocol's smart contract architecture, message format, or additional functionality, go to the [0x Improvement Proposals (ZEIPs)](https://github.com/0xProject/ZEIPs) repository and follow the contribution guidelines provided therein.
+
+Please read our [contribution guidelines](../../CONTRIBUTING.md) before getting started.

+## Contract extensions
+
+Smart contracts that implement extensions for the 0x protocol.
+
+## Usage
+
+Contract extensions of the protocol can be found in the [contracts](./contracts) directory. This directory contains contracts that interact with the 2.0.0 contracts and will be used in production, such as the [Forwarder](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/forwarder-specification.md) contract.
+
+## Bug bounty
+
+A bug bounty for the 2.0.0 contracts is ongoing! Instructions can be found [here](https://0xproject.com/wiki#Bug-Bounty).
+
+## Contributing
+
+We strongly recommend that the community help us make improvements and determine the future direction of the protocol. To report bugs within this package, please create an issue in this repository.
+
+For proposals regarding the 0x protocol's smart contract architecture, message format, or additional functionality, go to the [0x Improvement Proposals (ZEIPs)](https://github.com/0xProject/ZEIPs) repository and follow the contribution guidelines provided therein.
+
+Please read our [contribution guidelines](../../CONTRIBUTING.md) before getting started.
+
+### Install Dependencies
+
+If you don't have yarn workspaces enabled (Yarn < v1.0) - enable them:
+
+```bash
+yarn config set workspaces-experimental true
+```
+
+Then install dependencies
+
+```bash
+yarn install
+```
+
+### Build
+
+To build this package and all other monorepo packages that it depends on, run the following from the monorepo root directory:
+
+```bash
+PKG=@0x/contracts-extensions yarn build
+```
+
+Or continuously rebuild on change:
+
+```bash
+PKG=@0x/contracts-extensions yarn watch
+```
+
+### Clean
+
+```bash
+yarn clean
+```
+
+### Lint
+
+```bash
+yarn lint
+```
+
+### Run Tests
+
+```bash
+yarn test
+```
+
+#### Testing options
+
+Contracts testing options like coverage, profiling, revert traces or backing node choosing - are described [here](../TESTING.md).

+## Contract interfaces
+
+Smart contract interfaces of the 0x protocol.
+
+## Usage
+
+Contracts that make up and interact with version 2.0.0 of the protocol can be found in the [contracts](./contracts) directory. The contents of this directory are broken down into the following subdirectories:
+
+*   [protocol](./contracts/protocol)
+    *   This directory contains the contract interfaces that make up version 2.0.0. A full specification can be found [here](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/v2-specification.md).
+
+## Bug bounty
+
+A bug bounty for the 2.0.0 contracts is ongoing! Instructions can be found [here](https://0xproject.com/wiki#Bug-Bounty).
+
+## Contributing
+
+We strongly recommend that the community help us make improvements and determine the future direction of the protocol. To report bugs within this package, please create an issue in this repository.
+
+For proposals regarding the 0x protocol's smart contract architecture, message format, or additional functionality, go to the [0x Improvement Proposals (ZEIPs)](https://github.com/0xProject/ZEIPs) repository and follow the contribution guidelines provided therein.
+
+Please read our [contribution guidelines](../../CONTRIBUTING.md) before getting started.
+

+yarn config set workspaces-experimental true
+```
+
+Then install dependencies
+
+```bash
+yarn install
+```
+
+### Build
+
+To build this package and all other monorepo packages that it depends on, run the following from the monorepo root directory:
+
+```bash
+PKG=@0x/contracts-interfaces yarn build
+```
+
+Or continuously rebuild on change:
+
+```bash
+PKG=@0x/contracts-interfaces yarn watch
+```

+## Contracts libs
+
+Smart contracts libs used in the 0x protocol.
+
+## Usage
+
+Contracts can be found in the [contracts](./contracts) directory. The contents of this directory are broken down into the following subdirectories:
+
+*   [libs](./contracts/protocol)
+    *   This directory contains the libs.
+*   [test](./contracts/test)
+    *   This directory contains mocks and other contracts that are used solely for testing contracts within the other directories.
+
+## Contributing
+
+We strongly recommend that the community help us make improvements and determine the future direction of the protocol. To report bugs within this package, please create an issue in this repository.
+
+For proposals regarding the 0x protocol's smart contract architecture, message format, or additional functionality, go to the [0x Improvement Proposals (ZEIPs)](https://github.com/0xProject/ZEIPs) repository and follow the contribution guidelines provided therein.
+
+Please read our [contribution guidelines](../../CONTRIBUTING.md) before getting started.
+
+### Install Dependencies
+
+If you don't have yarn workspaces enabled (Yarn < v1.0) - enable them:
+
+```bash
+yarn config set workspaces-experimental true
+```
+
+Then install dependencies
+
+```bash
+yarn install
+```
+
+### Build
+
+To build this package and all other monorepo packages that it depends on, run the following from the monorepo root directory:
+
+```bash
+PKG=@0x/contracts-libs yarn build
+```
+
+Or continuously rebuild on change:
+
+```bash
+PKG=@0x/contracts-libs yarn watch
+```
+
+### Clean
+
+```bash
+yarn clean
+```

+## MultisSig Contracts
+
+MultiSig smart contracts
+
+## Usage
+
+Contracts can be found in the [contracts](./contracts) directory. The contents of this directory are broken down into the following subdirectories:
+
+*   [multisig](./contracts/multisig)
+    *   This directory contains the [Gnosis MultiSigWallet](https://github.com/gnosis/MultiSigWallet) and a custom extension that adds a timelock to transactions within the MultiSigWallet.
+*   [test](./contracts/test)
+    *   This directory contains mocks and other contracts that are used solely for testing contracts within the other directories.
+
+## Contributing
+
+We strongly recommend that the community help us make improvements and determine the future direction of the protocol. To report bugs within this package, please create an issue in this repository.
+
+For proposals regarding the 0x protocol's smart contract architecture, message format, or additional functionality, go to the [0x Improvement Proposals (ZEIPs)](https://github.com/0xProject/ZEIPs) repository and follow the contribution guidelines provided therein.
+
+Please read our [contribution guidelines](../../CONTRIBUTING.md) before getting started.
+
+### Install Dependencies

+```bash
+yarn config set workspaces-experimental true
+```
+
+Then install dependencies
+
+```bash
+yarn install
+```
+
+### Build
+
+To build this package and all other monorepo packages that it depends on, run the following from the monorepo root directory:
+
+```bash
+PKG=@0x/contracts-multisig yarn build
+```
+
+Or continuously rebuild on change:
+
+```bash
+PKG=@0x/contracts-multisig yarn watch
+```
+
+### Clean
+
+```bash
+yarn clean
+```
+
+### Lint
+
+```bash
+yarn lint
+```
+
+### Run Tests

+## Contracts
+
+Smart contracts that implement the 0x protocol. Addresses of the deployed contracts can be found in the 0x [wiki](https://0xproject.com/wiki#Deployed-Addresses) or the [CHANGELOG](./CHANGELOG.json) of this package.
+
+## Usage
+
+Contracts that make up and interact with version 2.0.0 of the protocol can be found in the [contracts](./contracts) directory. The contents of this directory are broken down into the following subdirectories:
+
+*   [protocol](./contracts/protocol)
+    *   This directory contains the contracts that make up version 2.0.0. A full specification can be found [here](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/v2-specification.md).
+*   [test](./contracts/test)
+    *   This directory contains mocks and other contracts that are used solely for testing contracts within the other directories.
+
+## Bug bounty
+
+A bug bounty for the 2.0.0 contracts is ongoing! Instructions can be found [here](https://0xproject.com/wiki#Bug-Bounty).
+

+## Token contracts
+
+Token smart contracts that are used in the 0x protocol. Addresses of the deployed contracts can be found in the 0x [wiki](https://0xproject.com/wiki#Deployed-Addresses) or the [CHANGELOG](./CHANGELOG.json) of this package.
+
+## Usage
+
+Token contracts that make up and interact with version 2.0.0 of the protocol can be found in the [contracts](./contracts) directory. The contents of this directory are broken down into the following subdirectories:
+
+*   [tokens](./contracts/tokens)
+    *   This directory contains implementations of different tokens and token standards, including [wETH](https://weth.io/), ZRX, [ERC20](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-20.md), and [ERC721](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-721.md).
+*   [test](./contracts/test)
+    *   This directory contains mocks and other contracts that are used solely for testing contracts within the other directories.
+
+## Bug bounty
+
+A bug bounty for the 2.0.0 contracts is ongoing! Instructions can be found [here](https://0xproject.com/wiki#Bug-Bounty).
+
+## Contributing
+
+We strongly recommend that the community help us make improvements and determine the future direction of the protocol. To report bugs within this package, please create an issue in this repository.
+
+For proposals regarding the 0x protocol's smart contract architecture, message format, or additional functionality, go to the [0x Improvement Proposals (ZEIPs)](https://github.com/0xProject/ZEIPs) repository and follow the contribution guidelines provided therein.
+
+Please read our [contribution guidelines](../../CONTRIBUTING.md) before getting started.
+

+## Contracts utils
+
+Smart contracts utils used in the 0x protocol.
+
+## Usage
+
+Contracts can be found in the [contracts](./contracts) directory. The contents of this directory are broken down into the following subdirectories:
+
+*   [utils](./contracts/utils)
+    *   This directory contains libraries and utils.
+*   [test](./contracts/test)
+    *   This directory contains mocks and other contracts that are used solely for testing contracts within the other directories.
+
+## Contributing
+
+We strongly recommend that the community help us make improvements and determine the future direction of the protocol. To report bugs within this package, please create an issue in this repository.
+
+For proposals regarding the 0x protocol's smart contract architecture, message format, or additional functionality, go to the [0x Improvement Proposals (ZEIPs)](https://github.com/0xProject/ZEIPs) repository and follow the contribution guidelines provided therein.
+
+Please read our [contribution guidelines](../../CONTRIBUTING.md) before getting started.
+

+yarn config set workspaces-experimental true
+```
+
+Then install dependencies
+
+```bash
+yarn install
+```
+
+### Build
+
+To build this package and all other monorepo packages that it depends on, run the following from the monorepo root directory:
+
+```bash
+PKG=@0x/contracts-utils yarn build

+The best way to get started is to copy [0x.js templates](https://github.com/0xProject/0x-monorepo/tree/development/packages/abi-gen-templates) and start adjusting them for your needs.
 We use [handlebars](http://handlebarsjs.com/) template engine under the hood.
 You need to have a master template called `contract.mustache`. it will be used to generate each contract wrapper. Although - you don't need and probably shouldn't write all your logic in a single template file. You can write [partial templates](http://handlebarsjs.com/partials.html) and as long as they are within a partials folder - they will be registered and available.

 ## @0x/asset-buyer
 
-**Warning: In Beta, has not been extensively tested.**
-
 Convenience package for buying assets represented on the Ethereum blockchain using 0x. In its simplest form, the package helps in the usage of the [0x forwarder contract](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/forwarder-specification.md), which allows users to execute [Wrapped Ether](https://weth.io/) based 0x orders without having to set allowances, wrap Ether or own ZRX, meaning they can buy tokens with Ether alone. Given some liquidity (0x signed orders), it helps estimate the Ether cost of buying a certain asset (giving a range) and then buying that asset.
 
 In its more advanced and useful form, it integrates with the [Standard Relayer API](https://github.com/0xProject/standard-relayer-api) and takes care of sourcing liquidity for you given an SRA compliant endpoint. The final result is a library that tells you what assets are available, provides an Ether based quote for any asset desired, and allows you to buy that asset using Ether alone.

-## Contracts
-
-Smart contracts that implement the 0x protocol. Addresses of the deployed contracts can be found in the 0x [wiki](https://0xproject.com/wiki#Deployed-Addresses) or the [CHANGELOG](./CHANGELOG.json) of this package.
-
-## Usage
-
-Contracts that make up and interact with version 2.0.0 of the protocol can be found in the [contracts](./contracts) directory. The contents of this directory are broken down into the following subdirectories:
-
-*   [protocol](./contracts/protocol)
-    *   This directory contains the contracts that make up version 2.0.0. A full specification can be found [here](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/v2-specification.md).
-*   [extensions](./contracts/extensions)
-    *   This directory contains contracts that interact with the 2.0.0 contracts and will be used in production, such as the [Forwarder](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/forwarder-specification.md) contract.
-*   [examples](./contracts/examples)
-    *   This directory contains example implementations of contracts that interact with the protocol but are _not_ intended for use in production. Examples include [filter](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/v2-specification.md#filter-contracts) contracts, a [Wallet](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/v2-specification.md#wallet) contract, and a [Validator](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/v2-specification.md#validator) contract, among others.
-*   [tokens](./contracts/tokens)
-    *   This directory contains implementations of different tokens and token standards, including [wETH](https://weth.io/), ZRX, [ERC20](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-20.md), and [ERC721](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-721.md).
-*   [multisig](./contracts/multisig)
-    *   This directory contains the [Gnosis MultiSigWallet](https://github.com/gnosis/MultiSigWallet) and a custom extension that adds a timelock to transactions within the MultiSigWallet.
-*   [utils](./contracts/utils)
-    *   This directory contains libraries and utils that are shared across all of the other directories.
-*   [test](./contracts/test)
-    *   This directory contains mocks and other contracts that are used solely for testing contracts within the other directories.
-
-## Bug bounty
-
-A bug bounty for the 2.0.0 contracts is ongoing! Instructions can be found [here](https://0xproject.com/wiki#Bug-Bounty).
-
-## Contributing
-
-We strongly recommend that the community help us make improvements and determine the future direction of the protocol. To report bugs within this package, please create an issue in this repository.
-
-For proposals regarding the 0x protocol's smart contract architecture, message format, or additional functionality, go to the [0x Improvement Proposals (ZEIPs)](https://github.com/0xProject/ZEIPs) repository and follow the contribution guidelines provided therein.
-
-Please read our [contribution guidelines](../../CONTRIBUTING.md) before getting started.
-
-### Install Dependencies
-
-If you don't have yarn workspaces enabled (Yarn < v1.0) - enable them:
-
-```bash
-yarn config set workspaces-experimental true
-```
-
-Then install dependencies
-
-```bash
-yarn install
-```
-
-### Build
-
-To build this package and all other monorepo packages that it depends on, run the following from the monorepo root directory:
-
-```bash
-PKG=contracts yarn build
-```
-
-Or continuously rebuild on change:
-
-```bash
-PKG=contracts yarn watch
-```
-
-### Clean
-
-```bash
-yarn clean
-```
-
-### Lint
-
-```bash
-yarn lint
-```
-
-### Run Tests
-
-```bash
-yarn test
-```
-
-#### Testing options
-
-###### Revert stack traces
-
-If you want to see helpful stack traces (incl. line number, code snippet) for smart contract reverts, run the tests with:
-
-```
-yarn test:trace
-```
-
-**Note:** This currently slows down the test runs and is therefore not enabled by default.
-
-###### Backing Ethereum node
-
-By default, our tests run against an in-process [Ganache](https://github.com/trufflesuite/ganache-core) instance. In order to run the tests against [Geth](https://github.com/ethereum/go-ethereum), first follow the instructions in the README for the devnet package to start the devnet Geth node. Then run:
-
-```bash
-TEST_PROVIDER=geth yarn test
-```
-
-###### Code coverage
-
-In order to see the Solidity code coverage output generated by `@0x/sol-cov`, run:
-
-```
-yarn test:coverage
-```
-
-###### Gas profiler
-
-In order to profile the gas costs for a specific smart contract call/transaction, you can run the tests in `profiler` mode.
-
-**Note:** Traces emitted by ganache have incorrect gas costs so we recommend using Geth for profiling.
-
-```
-TEST_PROVIDER=geth yarn test:profiler
-```
-
-You'll see a warning that you need to explicitly enable and disable the profiler before and after the block of code you want to profile.
-
-```typescript
-import { profiler } from './utils/profiler';
-profiler.start();
-// Some call to a smart contract
-profiler.stop();
-```
-
-Without explicitly starting and stopping the profiler, the profiler output will be too busy, and therefore unusable.

By contrast,\nthe GNU General Public License is intended to guarantee your freedom to\nshare and change all versions of a program--to make sure it remains free\nsoftware for all its users.  We, the Free Software Foundation, use the\nGNU General Public License for most of our software; it applies also to\nany other work released this way by its authors.  You can apply it to\nyour programs, too.\n\n  When we speak of free software, we are referring to freedom, not\nprice.  Our General Public Licenses are designed to make sure that you\nhave the freedom to distribute copies of free software (and charge for\nthem if you wish), that you receive source code or can get it if you\nwant it, that you can change the software or use pieces of it in new\nfree programs, and that you know you can do these things.\n\n  To protect your rights, we need to prevent others from denying you\nthese rights or asking you to surrender the rights.  Therefore, you have\ncertain responsibilities if you distribute copies of the software, or if\nyou modify it: responsibilities to respect the freedom of others.\n\n  For example, if you distribute copies of such a program, whether\ngratis or for a fee, you must pass on to the recipients the same\nfreedoms that you received.  You must make sure that they, too, receive\nor can get the source code.  And you must show them these terms so they\nknow their rights.\n\n  Developers that use the GNU GPL protect your rights with two steps:\n(1) assert copyright on the software, and (2) offer you this License\ngiving you legal permission to copy, distribute and/or modify it.\n\n  For the developers' and authors' protection, the GPL clearly explains\nthat there is no warranty for this free software.  For both users' and\nauthors' sake, the GPL requires that modified versions be marked as\nchanged, so that their problems will not be attributed erroneously to\nauthors of previous versions.\n\n  Some devices are designed to deny users access to install or run\nmodified versions of the software inside them, although the manufacturer\ncan do so.  This is fundamentally incompatible with the aim of\nprotecting users' freedom to change the software.  The systematic\npattern of such abuse occurs in the area of products for individuals to\nuse, which is precisely where it is most unacceptable.  Therefore, we\nhave designed this version of the GPL to prohibit the practice for those\nproducts.  If such problems arise substantially in other domains, we\nstand ready to extend this provision to those domains in future versions\nof the GPL, as needed to protect the freedom of users.\n\n  Finally, every program is threatened constantly by software patents.\nStates should not allow patents to restrict development and use of\nsoftware on general-purpose computers, but in those that do, we wish to\navoid the special danger that patents applied to a free program could\nmake it effectively proprietary.  To prevent this, the GPL assures that\npatents cannot be used to render the program non-free.\n\n  The precise terms and conditions for copying, distribution and\nmodification follow.\n\n                       TERMS AND CONDITIONS\n\n  0. Definitions.\n\n  \"This License\" refers to version 3 of the GNU General Public License.\n\n  \"Copyright\" also means copyright-like laws that apply to other kinds of\nworks, such as semiconductor masks.\n\n  \"The Program\" refers to any copyrightable work licensed under this\nLicense.  Each licensee is addressed as \"you\".  \"Licensees\" and\n\"recipients\" may be individuals or organizations.\n\n  To \"modify\" a work means to copy from or adapt all or part of the work\nin a fashion requiring copyright permission, other than the making of an\nexact copy.  The resulting work is called a \"modified version\" of the\nearlier work or a work \"based on\" the earlier work.\n\n  A \"covered work\" means either the unmodified Program or a work based\non the Program.\n\n  To \"propagate\" a work means to do anything with it that, without\npermission, would make you directly or secondarily liable for\ninfringement under applicable copyright law, except executing it on a\ncomputer or modifying a private copy.  Propagation includes copying,\ndistribution (with or without modification), making available to the\npublic, and in some countries other activities as well.\n\n  To \"convey\" a work means any kind of propagation that enables other\nparties to make or receive copies.  Mere interaction with a user through\na computer network, with no transfer of a copy, is not conveying.\n\n  An interactive user interface displays \"Appropriate Legal Notices\"\nto the extent that it includes a convenient and prominently visible\nfeature that (1) displays an appropriate copyright notice, and (2)\ntells the user that there is no warranty for the work (except to the\nextent that warranties are provided), that licensees may convey the\nwork under this License, and how to view a copy of this License.  If\nthe interface presents a list of user commands or options, such as a\nmenu, a prominent item in the list meets this criterion.\n\n  1. Source Code.\n\n  The \"source code\" for a work means the preferred form of the work\nfor making modifications to it.  \"Object code\" means any non-source\nform of a work.\n\n  A \"Standard Interface\" means an interface that either is an official\nstandard defined by a recognized standards body, or, in the case of\ninterfaces specified for a particular programming language, one that\nis widely used among developers working in that language.\n\n  The \"System Libraries\" of an executable work include anything, other\nthan the work as a whole, that (a) is included in the normal form of\npackaging a Major Component, but which is not part of that Major\nComponent, and (b) serves only to enable use of the work with that\nMajor Component, or to implement a Standard Interface for which an\nimplementation is available to the public in source code form.  A\n\"Major Component\", in this context, means a major essential component\n(kernel, window system, and so on) of the specific operating system\n(if any) on which the executable work runs, or a compiler used to\nproduce the work, or an object code interpreter used to run it.\n\n  The \"Corresponding Source\" for a work in object code form means all\nthe source code needed to generate, install, and (for an executable\nwork) run the object code and to modify the work, including scripts to\ncontrol those activities.  However, it does not include the work's\nSystem Libraries, or general-purpose tools or generally available free\nprograms which are used unmodified in performing those activities but\nwhich are not part of the work.  For example, Corresponding Source\nincludes interface definition files associated with source files for\nthe work, and the source code for shared libraries and dynamically\nlinked subprograms that the work is specifically designed to require,\nsuch as by intimate data communication or control flow between those\nsubprograms and other parts of the work.\n\n  The Corresponding Source need not include anything that users\ncan regenerate automatically from other parts of the Corresponding\nSource.\n\n  The Corresponding Source for a work in source code form is that\nsame work.\n\n  2. Basic Permissions.\n\n  All rights granted under this License are granted for the term of\ncopyright on the Program, and are irrevocable provided the stated\nconditions are met.  This License explicitly affirms your unlimited\npermission to run the unmodified Program.  The output from running a\ncovered work is covered by this License only if the output, given its\ncontent, constitutes a covered work.  This License acknowledges your\nrights of fair use or other equivalent, as provided by copyright law.\n\n  You may make, run and propagate covered works that you do not\nconvey, without conditions so long as your license otherwise remains\nin force.  You may convey covered works to others for the sole purpose\nof having them make modifications exclusively for you, or provide you\nwith facilities for running those works, provided that you comply with\nthe terms of this License in conveying all material for which you do\nnot control copyright.  Those thus making or running the covered works\nfor you must do so exclusively on your behalf, under your direction\nand control, on terms that prohibit them from making any copies of\nyour copyrighted material outside their relationship with you.\n\n  Conveying under any other circumstances is permitted solely under\nthe conditions stated below.  Sublicensing is not allowed; section 10\nmakes it unnecessary.\n\n  3. Protecting Users' Legal Rights From Anti-Circumvention Law.\n\n  No covered work shall be deemed part of an effective technological\nmeasure under any applicable law fulfilling obligations under article\n11 of the WIPO copyright treaty adopted on 20 December 1996, or\nsimilar laws prohibiting or restricting circumvention of such\nmeasures.\n\n  When you convey a covered work, you waive any legal power to forbid\ncircumvention of technological measures to the extent such circumvention\nis effected by exercising rights under this License with respect to\nthe covered work, and you disclaim any intention to limit operation or\nmodification of the work as a means of enforcing, against the work's\nusers, your or third parties' legal rights to forbid circumvention of\ntechnological measures.\n\n  4. Conveying Verbatim Copies.\n\n  You may convey verbatim copies of the Program's source code as you\nreceive it, in any medium, provided that you conspicuously and\nappropriately publish on each copy an appropriate copyright notice;\nkeep intact all notices stating that this License and any\nnon-permissive terms added in accord with section 7 apply to the code;\nkeep intact all notices of the absence of any warranty; and give all\nrecipients a copy of this License along with the Program.\n\n  You may charge any price or no price for each copy that you convey,\nand you may offer support or warranty protection for a fee.\n\n  5. Conveying Modified Source Versions.\n\n  You may convey a work based on the Program, or the modifications to\nproduce it from the Program, in the form of source code under the\nterms of section 4, provided that you also meet all of these conditions:\n\n    a) The work must carry prominent notices stating that you modified\n    it, and giving a relevant date.\n\n    b) The work must carry prominent notices stating that it is\n    released under this License and any conditions added under section\n    7.  This requirement modifies the requirement in section 4 to\n    \"keep intact all notices\".\n\n    c) You must license the entire work, as a whole, under this\n    License to anyone who comes into possession of a copy.  This\n    License will therefore apply, along with any applicable section 7\n    additional terms, to the whole of the work, and all its parts,\n    regardless of how they are packaged.  This License gives no\n    permission to license the work in any other way, but it does not\n    invalidate such permission if you have separately received it.\n\n    d) If the work has interactive user interfaces, each must display\n    Appropriate Legal Notices; however, if the Program has interactive\n    interfaces that do not display Appropriate Legal Notices, your\n    work need not make them do so.\n\n  A compilation of a covered work with other separate and independent\nworks, which are not by their nature extensions of the covered work,\nand which are not combined with it such as to form a larger program,\nin or on a volume of a storage or distribution medium, is called an\n\"aggregate\" if the compilation and its resulting copyright are not\nused to limit the access or legal rights of the compilation's users\nbeyond what the individual works permit.  Inclusion of a covered work\nin an aggregate does not cause this License to apply to the other\nparts of the aggregate.\n\n  6. Conveying Non-Source Forms.\n\n  You may convey a covered work in object code form under the terms\nof sections 4 and 5, provided that you also convey the\nmachine-readable Corresponding Source under the terms of this License,\nin one of these ways:\n\n    a) Convey the object code in, or embodied in, a physical product\n    (including a physical distribution medium), accompanied by the\n    Corresponding Source fixed on a durable physical medium\n    customarily used for software interchange.\n\n    b) Convey the object code in, or embodied in, a physical product\n    (including a physical distribution medium), accompanied by a\n    written offer, valid for at least three years and valid for as\n    long as you offer spare parts or customer support for that product\n    model, to give anyone who possesses the object code either (1) a\n    copy of the Corresponding Source for all the software in the\n    product that is covered by this License, on a durable physical\n    medium customarily used for software interchange, for a price no\n    more than your reasonable cost of physically performing this\n    conveying of source, or (2) access to copy the\n    Corresponding Source from a network server at no charge.\n\n    c) Convey individual copies of the object code with a copy of the\n    written offer to provide the Corresponding Source.  This\n    alternative is allowed only occasionally and noncommercially, and\n    only if you received the object code with such an offer, in accord\n    with subsection 6b.\n\n    d) Convey the object code by offering access from a designated\n    place (gratis or for a charge), and offer equivalent access to the\n    Corresponding Source in the same way through the same place at no\n    further charge.  You need not require recipients to copy the\n    Corresponding Source along with the object code.  If the place to\n    copy the object code is a network server, the Corresponding Source\n    may be on a different server (operated by you or a third party)\n    that supports equivalent copying facilities, provided you maintain\n    clear directions next to the object code saying where to find the\n    Corresponding Source.  Regardless of what server hosts the\n    Corresponding Source, you remain obligated to ensure that it is\n    available for as long as needed to satisfy these requirements.\n\n    e) Convey the object code using peer-to-peer transmission, provided\n    you inform other peers where the object code and Corresponding\n    Source of the work are being offered to the general public at no\n    charge under subsection 6d.\n\n  A separable portion of the object code, whose source code is excluded\nfrom the Corresponding Source as a System Library, need not be\nincluded in conveying the object code work.\n\n  A \"User Product\" is either (1) a \"consumer product\", which means any\ntangible personal property which is normally used for personal, family,\nor household purposes, or (2) anything designed or sold for incorporation\ninto a dwelling.  In determining whether a product is a consumer product,\ndoubtful cases shall be resolved in favor of coverage.  For a particular\nproduct received by a particular user, \"normally used\" refers to a\ntypical or common use of that class of product, regardless of the status\nof the particular user or of the way in which the particular user\nactually uses, or expects or is expected to use, the product.  A product\nis a consumer product regardless of whether the product has substantial\ncommercial, industrial or non-consumer uses, unless such uses represent\nthe only significant mode of use of the product.\n\n  \"Installation Information\" for a User Product means any methods,\nprocedures, authorization keys, or other information required to install\nand execute modified versions of a covered work in that User Product from\na modified version of its Corresponding Source.  The information must\nsuffice to ensure that the continued functioning of the modified object\ncode is in no case prevented or interfered with solely because\nmodification has been made.\n\n  If you convey an object code work under this section in, or with, or\nspecifically for use in, a User Product, and the conveying occurs as\npart of a transaction in which the right of possession and use of the\nUser Product is transferred to the recipient in perpetuity or for a\nfixed term (regardless of how the transaction is characterized), the\nCorresponding Source conveyed under this section must be accompanied\nby the Installation Information.  But this requirement does not apply\nif neither you nor any third party retains the ability to install\nmodified object code on the User Product (for example, the work has\nbeen installed in ROM).\n\n  The requirement to provide Installation Information does not include a\nrequirement to continue to provide support service, warranty, or updates\nfor a work that has been modified or installed by the recipient, or for\nthe User Product in which it has been modified or installed.  Access to a\nnetwork may be denied when the modification itself materially and\nadversely affects the operation of the network or violates the rules and\nprotocols for communication across the network.\n\n  Corresponding Source conveyed, and Installation Information provided,\nin accord with this section must be in a format that is publicly\ndocumented (and with an implementation available to the public in\nsource code form), and must require no special password or key for\nunpacking, reading or copying.\n\n  7. Additional Terms.\n\n  \"Additional permissions\" are terms that supplement the terms of this\nLicense by making exceptions from one or more of its conditions.\nAdditional permissions that are applicable to the entire Program shall\nbe treated as though they were included in this License, to the extent\nthat they are valid under applicable law.  If additional permissions\napply only to part of the Program, that part may be used separately\nunder those permissions, but the entire Program remains governed by\nthis License without regard to the additional permissions.\n\n  When you convey a copy of a covered work, you may at your option\nremove any additional permissions from that copy, or from any part of\nit.  (Additional permissions may be written to require their own\nremoval in certain cases when you modify the work.)  You may place\nadditional permissions on material, added by you to a covered work,\nfor which you have or can give appropriate copyright permission.\n\n  Notwithstanding any other provision of this License, for material you\nadd to a covered work, you may (if authorized by the copyright holders of\nthat material) supplement the terms of this License with terms:\n\n    a) Disclaiming warranty or limiting liability differently from the\n    terms of sections 15 and 16 of this License; or\n\n    b) Requiring preservation of specified reasonable legal notices or\n    author attributions in that material or in the Appropriate Legal\n    Notices displayed by works containing it; or\n\n    c) Prohibiting misrepresentation of the origin of that material, or\n    requiring that modified versions of such material be marked in\n    reasonable ways as different from the original version; or\n\n    d) Limiting the use for publicity purposes of names of licensors or\n    authors of the material; or\n\n    e) Declining to grant rights under trademark law for use of some\n    trade names, trademarks, or service marks; or\n\n    f) Requiring indemnification of licensors and authors of that\n    material by anyone who conveys the material (or modified versions of\n    it) with contractual assumptions of liability to the recipient, for\n    any liability that these contractual assumptions directly impose on\n    those licensors and authors.\n\n  All other non-permissive additional terms are considered \"further\nrestrictions\" within the meaning of section 10.  If the Program as you\nreceived it, or any part of it, contains a notice stating that it is\ngoverned by this License along with a term that is a further\nrestriction, you may remove that term.  If a license document contains\na further restriction but permits relicensing or conveying under this\nLicense, you may add to a covered work material governed by the terms\nof that license document, provided that the further restriction does\nnot survive such relicensing or conveying.\n\n  If you add terms to a covered work in accord with this section, you\nmust place, in the relevant source files, a statement of the\nadditional terms that apply to those files, or a notice indicating\nwhere to find the applicable terms.\n\n  Additional terms, permissive or non-permissive, may be stated in the\nform of a separately written license, or stated as exceptions;\nthe above requirements apply either way.\n\n  8. Termination.\n\n  You may not propagate or modify a covered work except as expressly\nprovided under this License.  Any attempt otherwise to propagate or\nmodify it is void, and will automatically terminate your rights under\nthis License (including any patent licenses granted under the third\nparagraph of section 11).\n\n  However, if you cease all violation of this License, then your\nlicense from a particular copyright holder is reinstated (a)\nprovisionally, unless and until the copyright holder explicitly and\nfinally terminates your license, and (b) permanently, if the copyright\nholder fails to notify you of the violation by some reasonable means\nprior to 60 days after the cessation.\n\n  Moreover, your license from a particular copyright holder is\nreinstated permanently if the copyright holder notifies you of the\nviolation by some reasonable means, this is the first time you have\nreceived notice of violation of this License (for any work) from that\ncopyright holder, and you cure the violation prior to 30 days after\nyour receipt of the notice.\n\n  Termination of your rights under this section does not terminate the\nlicenses of parties who have received copies or rights from you under\nthis License.  If your rights have been terminated and not permanently\nreinstated, you do not qualify to receive new licenses for the same\nmaterial under section 10.\n\n  9. Acceptance Not Required for Having Copies.\n\n  You are not required to accept this License in order to receive or\nrun a copy of the Program.  Ancillary propagation of a covered work\noccurring solely as a consequence of using peer-to-peer transmission\nto receive a copy likewise does not require acceptance.  However,\nnothing other than this License grants you permission to propagate or\nmodify any covered work.  These actions infringe copyright if you do\nnot accept this License.  Therefore, by modifying or propagating a\ncovered work, you indicate your acceptance of this License to do so.\n\n  10. Automatic Licensing of Downstream Recipients.\n\n  Each time you convey a covered work, the recipient automatically\nreceives a license from the original licensors, to run, modify and\npropagate that work, subject to this License.  You are not responsible\nfor enforcing compliance by third parties with this License.\n\n  An \"entity transaction\" is a transaction transferring control of an\norganization, or substantially all assets of one, or subdividing an\norganization, or merging organizations.  If propagation of a covered\nwork results from an entity transaction, each party to that\ntransaction who receives a copy of the work also receives whatever\nlicenses to the work the party's predecessor in interest had or could\ngive under the previous paragraph, plus a right to possession of the\nCorresponding Source of the work from the predecessor in interest, if\nthe predecessor has it or can get it with reasonable efforts.\n\n  You may not impose any further restrictions on the exercise of the\nrights granted or affirmed under this License.  For example, you may\nnot impose a license fee, royalty, or other charge for exercise of\nrights granted under this License, and you may not initiate litigation\n(including a cross-claim or counterclaim in a lawsuit) alleging that\nany patent claim is infringed by making, using, selling, offering for\nsale, or importing the Program or any portion of it.\n\n  11. Patents.\n\n  A \"contributor\" is a copyright holder who authorizes use under this\nLicense of the Program or a work on which the Program is based.  The\nwork thus licensed is called the contributor's \"contributor version\".\n\n  A contributor's \"essential patent claims\" are all patent claims\nowned or controlled by the contributor, whether already acquired or\nhereafter acquired, that would be infringed by some manner, permitted\nby this License, of making, using, or selling its contributor version,\nbut do not include claims that would be infringed only as a\nconsequence of further modification of the contributor version.  For\npurposes of this definition, \"control\" includes the right to grant\npatent sublicenses in a manner consistent with the requirements of\nthis License.\n\n  Each contributor grants you a non-exclusive, worldwide, royalty-free\npatent license under the contributor's essential patent claims, to\nmake, use, sell, offer for sale, import and otherwise run, modify and\npropagate the contents of its contributor version.\n\n  In the following three paragraphs, a \"patent license\" is any express\nagreement or commitment, however denominated, not to enforce a patent\n(such as an express permission to practice a patent or covenant not to\nsue for patent infringement).  To \"grant\" such a patent license to a\nparty means to make such an agreement or commitment not to enforce a\npatent against the party.\n\n  If you convey a covered work, knowingly relying on a patent license,\nand the Corresponding Source of the work is not available for anyone\nto copy, free of charge and under the terms of this License, through a\npublicly available network server or other readily accessible means,\nthen you must either (1) cause the Corresponding Source to be so\navailable, or (2) arrange to deprive yourself of the benefit of the\npatent license for this particular work, or (3) arrange, in a manner\nconsistent with the requirements of this License, to extend the patent\nlicense to downstream recipients.  \"Knowingly relying\" means you have\nactual knowledge that, but for the patent license, your conveying the\ncovered work in a country, or your recipient's use of the covered work\nin a country, would infringe one or more identifiable patents in that\ncountry that you have reason to believe are valid.\n\n  If, pursuant to or in connection with a single transaction or\narrangement, you convey, or propagate by procuring conveyance of, a\ncovered work, and grant a patent license to some of the parties\nreceiving the covered work authorizing them to use, propagate, modify\nor convey a specific copy of the covered work, then the patent license\nyou grant is automatically extended to all recipients of the covered\nwork and works based on it.\n\n  A patent license is \"discriminatory\" if it does not include within\nthe scope of its coverage, prohibits the exercise of, or is\nconditioned on the non-exercise of one or more of the rights that are\nspecifically granted under this License.  You may not convey a covered\nwork if you are a party to an arrangement with a third party that is\nin the business of distributing software, under which you make payment\nto the third party based on the extent of your activity of conveying\nthe work, and under which the third party grants, to any of the\nparties who would receive the covered work from you, a discriminatory\npatent license (a) in connection with copies of the covered work\nconveyed by you (or copies made from those copies), or (b) primarily\nfor and in connection with specific products or compilations that\ncontain the covered work, unless you entered into that arrangement,\nor that patent license was granted, prior to 28 March 2007.\n\n  Nothing in this License shall be construed as excluding or limiting\nany implied license or other defenses to infringement that may\notherwise be available to you under applicable patent law.\n\n  12. No Surrender of Others' Freedom.\n\n  If conditions are imposed on you (whether by court order, agreement or\notherwise) that contradict the conditions of this License, they do not\nexcuse you from the conditions of this License.  If you cannot convey a\ncovered work so as to satisfy simultaneously your obligations under this\nLicense and any other pertinent obligations, then as a consequence you may\nnot convey it at all.  For example, if you agree to terms that obligate you\nto collect a royalty for further conveying from those to whom you convey\nthe Program, the only way you could satisfy both those terms and this\nLicense would be to refrain entirely from conveying the Program.\n\n  13. Use with the GNU Affero General Public License.\n\n  Notwithstanding any other provision of this License, you have\npermission to link or combine any covered work with a work licensed\nunder version 3 of the GNU Affero General Public License into a single\ncombined work, and to convey the resulting work.  The terms of this\nLicense will continue to apply to the part which is the covered work,\nbut the special requirements of the GNU Affero General Public License,\nsection 13, concerning interaction through a network will apply to the\ncombination as such.\n\n  14. Revised Versions of this License.\n\n  The Free Software Foundation may publish revised and/or new versions of\nthe GNU General Public License from time to time.  Such new versions will\nbe similar in spirit to the present version, but may differ in detail to\naddress new problems or concerns.\n\n  Each version is given a distinguishing version number.  If the\nProgram specifies that a certain numbered version of the GNU General\nPublic License \"or any later version\" applies to it, you have the\noption of following the terms and conditions either of that numbered\nversion or of any later version published by the Free Software\nFoundation.  If the Program does not specify a version number of the\nGNU General Public License, you may choose any version ever published\nby the Free Software Foundation.\n\n  If the Program specifies that a proxy can decide which future\nversions of the GNU General Public License can be used, that proxy's\npublic statement of acceptance of a version permanently authorizes you\nto choose that version for the Program.\n\n  Later license versions may give you additional or different\npermissions.  However, no additional obligations are imposed on any\nauthor or copyright holder as a result of your choosing to follow a\nlater version.\n\n  15. Disclaimer of Warranty.\n\n  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY\nAPPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT\nHOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM \"AS IS\" WITHOUT WARRANTY\nOF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,\nTHE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR\nPURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM\nIS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF\nALL NECESSARY SERVICING, REPAIR OR CORRECTION.\n\n  16. Limitation of Liability.\n\n  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING\nWILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS\nTHE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY\nGENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE\nUSE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF\nDATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD\nPARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),\nEVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF\nSUCH DAMAGES.\n\n  17. Interpretation of Sections 15 and 16.\n\n  If the disclaimer of warranty and limitation of liability provided\nabove cannot be given local legal effect according to their terms,\nreviewing courts shall apply local law that most closely approximates\nan absolute waiver of all civil liability in connection with the\nProgram, unless a warranty or assumption of liability accompanies a\ncopy of the Program in return for a fee.\n\n                     END OF TERMS AND CONDITIONS\n\n            How to Apply These Terms to Your New Programs\n\n  If you develop a new program, and you want it to be of the greatest\npossible use to the public, the best way to achieve this is to make it\nfree software which everyone can redistribute and change under these terms.\n\n  To do so, attach the following notices to the program.  It is safest\nto attach them to the start of each source file to most effectively\nstate the exclusion of warranty; and each file should have at least\nthe \"copyright\" line and a pointer to where the full notice is found.\n\n    <one line to give the program's name and a brief idea of what it does.>\n    Copyright (C) <year>  <name of author>\n\n    This program is free software: you can redistribute it and/or modify\n    it under the terms of the GNU General Public License as published by\n    the Free Software Foundation, either version 3 of the License, or\n    (at your option) any later version.\n\n    This program is distributed in the hope that it will be useful,\n    but WITHOUT ANY WARRANTY; without even the implied warranty of\n    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the\n    GNU General Public License for more details.\n\n    You should have received a copy of the GNU General Public License\n    along with this program.  If not, see <http://www.gnu.org/licenses/>.\n\nAlso add information on how to contact you by electronic and paper mail.\n\n  If the program does terminal interaction, make it output a short\nnotice like this when it starts in an interactive mode:\n\n    <program>  Copyright (C) <year>  <name of author>\n    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.\n    This is free software, and you are welcome to redistribute it\n    under certain conditions; type `show c' for details.\n\nThe hypothetical commands `show w' and `show c' should show the appropriate\nparts of the General Public License.  Of course, your program's commands\nmight be different; for a GUI interface, you would use an \"about box\".\n\n  You should also get your employer (if you work as a programmer) or school,\nif any, to sign a \"copyright disclaimer\" for the program, if necessary.\nFor more information on this, and how to apply and follow the GNU GPL, see\n<http://www.gnu.org/licenses/>.\n\n  The GNU General Public License does not permit incorporating your program\ninto proprietary programs.  If your program is a subroutine library, you\nmay consider it more useful to permit linking proprietary applications with\nthe library.  If this is what you want to do, use the GNU Lesser General\nPublic License instead of this License.  But first, please read\n<http://www.gnu.org/philosophy/why-not-lgpl.html>.\n\n*/\n"

- * Tests the behavior of a test function by comparing it to the expected

- * test function will be called to obtain an "actual result", or if the test
- * function throws/rejects, an "actual error". The test passes if at least one

- *
- * 1) Neither the reference function or the test function throw and the
- * "expected result" equals the "actual result".
- *
- * 2) Both the reference function and the test function throw and the "actual
- * error" message *contains* the "expected error" message.
- *
- * @param referenceFuncAsync a reference function implemented in pure
- * JavaScript/TypeScript which accepts N arguments and returns the "expected
- * result" or throws/rejects with the "expected error".
- * @param testFuncAsync a test function which, e.g., makes a call or sends a
- * transaction to a contract. It accepts the same N arguments returns the
- * "actual result" or throws/rejects with the "actual error".
- * @param values an array of N values, where each value corresponds in-order to
- * an argument to both the test function and the reference function.
- * @return A Promise that resolves if the test passes and rejects if the test
- * fails, according to the rules described above.

+## Troubleshooting
+
+If you are still seeing TS type errors complaining about missing DOM types such as `Response`:
+
+```
+error TS2304: Cannot find name 'Response'.
+```
+
+Then you need to explicitly add the `dom` lib to your compiler options in `tsconfig.json`. The `dom` library is included by default, but customizing the `lib` option can cause it to be dropped.

+### Publish
+
+#### 0x Ganache Snapshot
+
+The 0x Ganache snapshot can be generated and published in this package. In order to build the snapshot for this version of migrations run:
+
+```bash
+yarn build:snapshot
+```
+
+This will run the migrations in Ganache and output a zip file to be uploaded to the s3 bucket. For example, after running this command you will have created `0x_ganache_snapshot-2.2.2.zip`. To publish the zip file to the s3 bucket run:
+
+```bash
+yarn publish:snapshot
+```
+
+This snapshot will now be publicly available at http://ganache-snapshots.0x.org.s3.amazonaws.com/0x_ganache_snapshot-latest.zip and also versioned with the package.json version.
+
+#### 0x Ganache Docker Image
+
+We also publish a simple docker image which downloads the latest snapshot, extracts and runs Ganache. This is not required to be built when migrations change as it always downloads and runs the latest zip file. If you have made changes to the Dockerfile then a publish of the image is required. To do this run:
+
+```bash
+yarn build:snapshot:docker
+yarn publish:snapshot:docker
+```
+
+The result is a published docker image to the 0xorg docker registry. To start the docker image run:
+
+```bash
+docker run -p 8545:8545 -ti 0xorg/ganache-cli:latest
+```
+
+This will pull the latest zip in the s3 bucket, extract and start Ganache with the snapshot.
+
+In the event you need a specific version of the published Ganache snapshot run the following specifying the VERSION environment variable:
+
+```bash
+docker run -e VERSION=2.2.2 -p 8545:8545 -ti 0xorg/ganache-cli:latest
+```

 #### Read the wiki [article](https://0xproject.com/wiki#0x-OrderWatcher).
 
+OrderWatcher also comes with a WebSocket server to provide language-agnostic access
+to order watching functionality. We used the [WebSocket Client and Server Implementation for Node](https://www.npmjs.com/package/websocket). The server sends and receives messages that conform to the [JSON RPC specifications](https://www.jsonrpc.org/specification).
+
 ## Installation

 }
 ```
 
+## Using the WebSocket Server
+
+**Setup**
+
+**Environmental Variables**
+Several environmental variables can be set to configure the server:
+
+*   `ORDER_WATCHER_HTTP_PORT` specifies the port that the http server will listen on
+    and accept connections from. When this is not set, we default to 8080.
+
+**Requests**
+The server accepts three types of requests: `ADD_ORDER`, `REMOVE_ORDER` and `GET_STATS`. These mirror what the underlying OrderWatcher does. You can read more in the [wiki](https://0xproject.com/wiki#0x-OrderWatcher). Unlike the OrderWatcher, it does not expose any `subscribe` or `unsubscribe` functionality because the WebSocket server keeps a single subscription open for all clients.
+
+The first step for making a request is establishing a connection with the server. In Javascript:
+
+```
+var W3CWebSocket = require('websocket').w3cwebsocket;
+wsClient = new W3CWebSocket('ws://127.0.0.1:8080');
+```
+
+In Python, you could use the [websocket-client library](http://pypi.python.org/pypi/websocket-client/) and run:
+
+```
+from websocket import create_connection
+wsClient = create_connection("ws://127.0.0.1:8080")
+```
+
+With the connection established, you prepare the payload for your request. The payload is a json object with a format established by the [JSON RPC specification](https://www.jsonrpc.org/specification):
+
+*   `id`: All requests require you to specify a numerical `id`. When the server responds to the request, the response will have the same `id` as the one supplied with your request.
+*   `jsonrpc`: This is always the string `'2.0'`.
+*   `method`: This specifies the OrderWatcher method you want to call. I.e., `'ADD_ORDER'`, `'REMOVE_ORDER'` or `'GET_STATS'`.
+*   `params`: These contain the parameters needed by OrderWatcher to execute the method you called. For `ADD_ORDER`, provide `{ signedOrder: <your signedOrder> }`. For `REMOVE_ORDER`, provide `{ orderHash: <your orderHash> }`. For `GET_STATS`, no parameters are needed, so you may leave this empty.
+
+Next, convert the payload to a string and send it through the connection.
+In Javascript:
+
+```
+const addOrderPayload = {
+    id: 1,
+    jsonrpc: '2.0',
+    method: 'ADD_ORDER',
+    params: { signedOrder: <your signedOrder> },
+};
+wsClient.send(JSON.stringify(addOrderPayload));
+```
+
+In Python:
+
+```
+import json
+remove_order_payload = {
+    'id': 1,
+    'jsonrpc': '2.0',
+    'method': 'REMOVE_ORDER',
+    'params': {'orderHash': '0x6edc16bf37fde79f5012088c33784c730e2f103d9ab1caf73060c386ad107b7e'},
+}
+wsClient.send(json.dumps(remove_order_payload));
+```
+
+**Response**
+The server responds to all requests in a similar format. In the data field, you'll find another object containing the following fields:
+
+*   `id`: The id corresponding to the request that the server is responding to. `UPDATE` responses are not based on any requests so the `id` field is omitted`.
+*   `jsonrpc`: Always `'2.0'`.
+*   `method`: The method the server is responding to. Eg. `ADD_ORDER`. When order states change the server may also initiate a response. In this case, method will be listed as `UPDATE`.
+*   `result`: This field varies based on the method. `UPDATE` responses contain the new order state. `GET_STATS` responses contain the current order count. When there are errors, this field is omitted.
+*   `error`: When there is an error executing a request, the [JSON RPC](https://www.jsonrpc.org/specification) error object is listed here. When the server responds successfully, this field is omitted.
+
+In Javascript, the responses can be parsed using the `onmessage` callback:
+
+```
+wsClient.onmessage = (msg) => {
+    const responseData = JSON.parse(msg.data);
+    const method = responseData.method
+};
+```
+
+In Python, `recv` is a lightweight way to receive a response:
+
+```
+result = wsClient.recv()
+method = result.method
+```
+

+## @0xproject/pipeline
+
+This repository contains scripts used for scraping data from the Ethereum blockchain into SQL tables for analysis by the 0x team.
+
+## Contributing
+
+We strongly recommend that the community help us make improvements and determine the future direction of the protocol. To report bugs within this package, please create an issue in this repository.
+
+Please read our [contribution guidelines](../../CONTRIBUTING.md) before getting started.
+
+### Install dependencies:
+
+```bash
+yarn install
+```
+
+### Build
+
+```bash
+yarn build
+```
+
+### Clean
+
+```bash
+yarn clean
+```
+
+### Lint
+
+```bash
+yarn lint
+```
+
+### Migrations
+
+Create a new migration: `yarn migrate:create --name MigrationNameInCamelCase`
+Run migrations: `yarn migrate:run`
+Revert the most recent migration (CAUTION: may result in data loss!): `yarn migrate:revert`
+
+## Testing
+
+There are several test scripts in **package.json**. You can run all the tests
+with `yarn test:all` or run certain tests seprately by following the
+instructions below. Some tests may not work out of the box on certain platforms
+or operating systems (see the "Database tests" section below).
+
+### Unit tests
+
+The unit tests can be run with `yarn test`. These tests don't depend on any
+services or databases and will run in any environment that can run Node.
+
+### Database tests
+
+Database integration tests can be run with `yarn test:db`. These tests will
+attempt to automatically spin up a Postgres database via Docker. If this doesn't
+work you have two other options:
+
+1.  Set the `DOCKER_SOCKET` environment variable to a valid socket path to use
+    for communicating with Docker.
+2.  Start Postgres manually and set the `ZEROEX_DATA_PIPELINE_TEST_DB_URL`
+    environment variable. If this is set, the tests will use your existing
+    Postgres database instead of trying to create one with Docker.
+
+## Running locally
+
+`pipeline` requires access to a PostgreSQL database. The easiest way to start
+Postgres is via Docker. Depending on your platform, you may need to prepend
+`sudo` to the following command:
+
+```
+docker run --rm -d -p 5432:5432 --name pipeline_postgres postgres:11-alpine
+```
+
+This will start a Postgres server with the default username and database name
+(`postgres` and `postgres`). You should set the environment variable as follows:
+
+```
+export ZEROEX_DATA_PIPELINE_DB_URL=postgresql://postgres@localhost/postgres
+```
+
+First thing you will need to do is run the migrations:
+
+```
+yarn migrate:run
+```
+
+Now you can run scripts locally:
+
+```
+node packages/pipeline/lib/src/scripts/pull_radar_relay_orders.js
+```
+
+To stop the Postgres server (you may need to add `sudo`):
+
+```
+docker stop pipeline_postgres
+```
+
+This will remove all data from the database.
+
+If you prefer, you can also install Postgres with e.g.,
+[Homebrew](https://wiki.postgresql.org/wiki/Homebrew) or
+[Postgress.app](https://postgresapp.com/). Keep in mind that you will need to
+set the`ZEROEX_DATA_PIPELINE_DB_URL` environment variable to a valid
+[PostgreSQL connection url](https://stackoverflow.com/questions/3582552/postgresql-connection-url)
+
+## Directory structure
+
+```

+├── lib: Code generated by the TypeScript compiler. Don't edit this directly.

+```
+
+## Adding new data to the pipeline
+
+1.  Create an entity in the _entities_ directory. Entities directly mirror our
+    database schemas. We follow the practice of having "dumb" entities, so
+    entity classes should typically not have any methods.
+2.  Create a migration using the `yarn migrate:create` command. Create/update
+    tables as needed. Remember to fill in both the `up` and `down` methods. Try
+    to avoid data loss as much as possible in your migrations.
+3.  Add basic tests for your entity and migrations to the **test/entities/**
+    directory.
+4.  Create a class or function in the **data_sources/** directory for getting
+    raw data. This code should abstract away pagination and rate-limiting as
+    much as possible.
+5.  Create a class or function in the **parsers/** directory for converting the
+    raw data into an entity. Also add tests in the **tests/** directory to test
+    the parser.
+6.  Create an executable script in the **scripts/** directory for putting
+    everything together. Your script can accept environment variables for things
+    like API keys. It should pull the data, parse it, and save it to the
+    database. Scripts should be idempotent and atomic (when possible). What this
+    means is that your script may be responsible for determining _which_ data
+    needs to be updated. For example, you may need to query the database to find
+    the most recent block number that we have already pulled, then pull new data
+    starting from that block number.
+7.  Run the migrations and then run your new script locally and verify it works
+    as expected.
+
+#### Additional guidelines and tips:
+
+*   Table names should be plural and separated by underscores (e.g.,
+    `exchange_fill_events`).
+*   Any table which contains data which comes directly from a third-party source
+    should be namespaced in the `raw` PostgreSQL schema.
+*   Column names in the database should be separated by underscores (e.g.,
+    `maker_asset_type`).
+*   Field names in entity classes (like any other fields in TypeScript) should
+    be camel-cased (e.g., `makerAssetType`).
+*   All timestamps should be stored as milliseconds since the Unix Epoch.
+*   Use the `BigNumber` type for TypeScript code which deals with 256-bit
+    numbers from smart contracts or for any case where we are dealing with large
+    floating point numbers.
+*   [TypeORM documentation](http://typeorm.io/#/) is pretty robust and can be a
+    helpful resource.

+     * @TODO #1:
+     *   This optimization strategy handles blocks that are exact duplicates of one another.
+     *   But what if some block is a combination of two other blocks? Or a subset of another block?
+     *   This optimization problem is not much different from the current implemetation.
+     *   Instead of tracking "observed" hashes, at each node we would simply do pattern-matching on the calldata.
+     *   This strategy would be applied after assigning offsets to the tree, rather than before (as in this strategy).

+     *
+     * @TODO #2:
+     *   To be done as a follow-up to @TODO #1.
+     *   Since we optimize from the bottom-up, we could be affecting the outcome of a later potential optimization.
+     *   For example, what if by removing one duplicate value we miss out on optimizing another block higher in the tree.
+     *   To handle this case, at each node we can store a candidate optimization in a priority queue (sorted by calldata size).
+     *   At the end of traversing the tree, the candidate at the front of the queue will be the most optimal output.

+## 0x-json-schemas
+
+0x JSON schemas for those developing on top of 0x protocol.
+
+Read the [documentation](http://0x-json-schemas-py.s3-website-us-east-1.amazonaws.com/)
+
+## Installing
+
+```bash
+pip install 0x-json-schemas
+```
+
+## Contributing
+
+We welcome improvements and fixes from the wider community! To report bugs within this package, please create an issue in this repository.
+
+Please read our [contribution guidelines](../../CONTRIBUTING.md) before getting started.
+
+### Install Code and Dependencies
+
+Ensure that you have installed Python >=3.6 and Docker. Then:
+
+```bash
+pip install -e .[dev]
+```
+
+### Test
+
+Tests depend on a running ganache instance with the 0x contracts deployed in it. For convenience, a docker container is provided that has ganache-cli and a snapshot containing the necessary contracts. A shortcut is provided to run that docker container: `./setup.py ganache`. With that running, the tests can be run with `./setup.py test`.

+# 0x-sra-client
+
+A Python client for interacting with servers conforming to [the Standard Relayer API specification](https://github.com/0xProject/0x-monorepo/tree/development/packages/sra-spec).
+
+# Schemas
+
+The [JSON schemas](http://json-schema.org/) for the API payloads and responses can be found in [@0xproject/json-schemas](https://github.com/0xProject/0x.js/tree/development/packages/json-schemas). Examples of each payload and response can be found in the 0x.js library's [test suite](https://github.com/0xProject/0x.js/blob/development/packages/json-schemas/test/schema_test.ts#L1).
+
+```bash
+pip install 0x-json-schemas
+```
+
+You can easily validate your API's payloads and responses using the [0x-json-schemas](https://github.com/0xProject/0x.js/tree/development/python-packages/json_schemas) package:
+
+```python
+from zero_ex.json_schemas import assert_valid
+from zero_ex.order_utils import Order
+
+order: Order = {
+    'makerAddress': "0x0000000000000000000000000000000000000000",
+    'takerAddress': "0x0000000000000000000000000000000000000000",
+    'feeRecipientAddress': "0x0000000000000000000000000000000000000000",
+    'senderAddress': "0x0000000000000000000000000000000000000000",

+}
+
+assert_valid(order, "/orderSchema")
+```
+
+# Pagination
+
+Requests that return potentially large collections should respond to the **?page** and **?perPage** parameters. For example:
+
+```bash
+$ curl https://api.example-relayer.com/v2/asset_pairs?page=3&perPage=20
+```
+
+Page numbering should be 1-indexed, not 0-indexed. If a query provides an unreasonable (ie. too high) `perPage` value, the response can return a validation error as specified in the [errors section](#section/Errors). If the query specifies a `page` that does not exist (ie. there are not enough `records`), the response should just return an empty `records` array.
+
+All endpoints that are paginated should return a `total`, `page`, `perPage` and a `records` value in the top level of the collection. The value of `total` should be the total number of records for a given query, whereas `records` should be an array representing the response to the query for that page. `page` and `perPage`, are the same values that were specified in the request. See the note in [miscellaneous](#section/Misc.) about formatting `snake_case` vs. `lowerCamelCase`.
+
+These requests include the [`/v2/asset_pairs`](#operation/getAssetPairs), [`/v2/orders`](#operation/getOrders), [`/v2/fee_recipients`](#operation/getFeeRecipients) and [`/v2/orderbook`](#operation/getOrderbook) endpoints.
+
+# Network Id
+
+All requests should be able to specify a **?networkId** query param for all supported networks. For example:
+
+```bash
+$ curl https://api.example-relayer.com/v2/asset_pairs?networkId=1
+```
+
+If the query param is not provided, it should default to **1** (mainnet).
+
+Networks and their Ids:
+
+| Network Id | Network Name |
+| ---------- | ------------ |
+| 1          | Mainnet      |
+| 42         | Kovan        |
+| 3          | Ropsten      |
+| 4          | Rinkeby      |
+
+If a certain network is not supported, the response should **400** as specified in the [error response](#section/Errors) section. For example:
+
+```json
+{
+    \"code\": 100,
+    \"reason\": \"Validation failed\",
+    \"validationErrors\": [
+        {
+            \"field\": \"networkId\",
+            \"code\": 1006,
+            \"reason\": \"Network id 42 is not supported\"
+        }
+    ]
+}
+```
+
+# Link Header
+
+A [Link Header](https://tools.ietf.org/html/rfc5988) can be included in a response to provide clients with more context about paging
+For example:
+
+```bash
+Link: <https://api.example-relayer.com/v2/asset_pairs?page=3&perPage=20>; rel=\"next\",
+<https://api.github.com/user/repos?page=10&perPage=20>; rel=\"last\"
+```
+
+This `Link` response header contains one or more Hypermedia link relations.
+
+The possible `rel` values are:
+
+| Name  | Description                                                   |
+| ----- | ------------------------------------------------------------- |
+| next  | The link relation for the immediate next page of results.     |
+| last  | The link relation for the last page of results.               |
+| first | The link relation for the first page of results.              |
+| prev  | The link relation for the immediate previous page of results. |
+
+# Rate Limits
+
+Rate limit guidance for clients can be optionally returned in the response headers:
+
+| Header Name           | Description                                                                  |
+| --------------------- | ---------------------------------------------------------------------------- |
+| X-RateLimit-Limit     | The maximum number of requests you're permitted to make per hour.            |
+| X-RateLimit-Remaining | The number of requests remaining in the current rate limit window.           |
+| X-RateLimit-Reset     | The time at which the current rate limit window resets in UTC epoch seconds. |
+
+For example:
+
+```bash
+$ curl -i https://api.example-relayer.com/v2/asset_pairs
+HTTP/1.1 200 OK
+Date: Mon, 20 Oct 2017 12:30:06 GMT
+Status: 200 OK
+X-RateLimit-Limit: 60
+X-RateLimit-Remaining: 56
+X-RateLimit-Reset: 1372700873
+```
+
+When a rate limit is exceeded, a status of **429 Too Many Requests** should be returned.
+
+# Errors
+
+Unless the spec defines otherwise, errors to bad requests should respond with HTTP 4xx or status codes.
+
+## Common error codes
+
+| Code | Reason                                  |
+| ---- | --------------------------------------- |
+| 400  | Bad Request – Invalid request format    |
+| 404  | Not found                               |
+| 429  | Too many requests - Rate limit exceeded |
+| 500  | Internal Server Error                   |
+| 501  | Not Implemented                         |
+
+## Error reporting format
+
+For all **400** responses, see the [error response schema](https://github.com/0xProject/0x-monorepo/blob/development/packages/json-schemas/schemas/relayer_api_error_response_schema.ts#L1).
+
+```json
+{
+    \"code\": 101,
+    \"reason\": \"Validation failed\",
+    \"validationErrors\": [
+        {
+            \"field\": \"maker\",
+            \"code\": 1002,
+            \"reason\": \"Invalid address\"
+        }
+    ]
+}
+```
+
+General error codes:
+
+```bash
+100 - Validation Failed
+101 - Malformed JSON
+102 - Order submission disabled
+103 - Throttled
+```
+
+Validation error codes:
+
+```bash
+1000 - Required field
+1001 - Incorrect format
+1002 - Invalid address
+1003 - Address not supported
+1004 - Value out of range
+1005 - Invalid signature or hash
+1006 - Unsupported option
+```
+
+# Asset Data Encoding
+
+As we now support multiple [token transfer proxies](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/v2-specification.md#assetproxy), the identifier of which proxy to use for the token transfer must be encoded, along with the token information. Each proxy in 0x v2 has a unique identifier. If you're using 0x.js there will be helper methods for this [encoding](https://0xproject.com/docs/0x.js#zeroEx-encodeERC20AssetData) and [decoding](https://0xproject.com/docs/0x.js#zeroEx-decodeAssetProxyId).
+
+The identifier for the Proxy uses a similar scheme to [ABI function selectors](https://github.com/ethereum/wiki/wiki/Ethereum-Contract-ABI#function-selector).
+
+```js
+// ERC20 Proxy ID  0xf47261b0
+bytes4(keccak256('ERC20Token(address)'));
+// ERC721 Proxy ID 0x02571792
+bytes4(keccak256('ERC721Token(address,uint256)'));
+```
+
+Asset data is encoded using [ABI encoding](https://solidity.readthedocs.io/en/develop/abi-spec.html).
+
+For example, encoding the ERC20 token contract (address: 0x1dc4c1cefef38a777b15aa20260a54e584b16c48) using the ERC20 Transfer Proxy (id: 0xf47261b0) would be:
+
+```bash
+0xf47261b00000000000000000000000001dc4c1cefef38a777b15aa20260a54e584b16c48
+```
+
+Encoding the ERC721 token contract (address: `0x371b13d97f4bf77d724e78c16b7dc74099f40e84`), token id (id: `99`, which hex encoded is `0x63`) and the ERC721 Transfer Proxy (id: 0x02571792) would be:

+
+# Meta Data in Order Responses
+
+In v2 of the standard relayer API we added the `metaData` field. It is meant to provide a standard place for relayers to put optional, custom or non-standard fields that may of interest to the consumer of the API.
+
+A good example of such a field is `remainingTakerAssetAmount`, which is a convenience field that communicates how much of a 0x order is potentially left to be filled. Unlike the other fields in a 0x order, it is not guaranteed to be correct as it is derived from whatever mechanism the implementer (ie. the relayer) is using. While convenient for prototyping and low stakes situations, we recommend validating the value of the field by checking the state of the blockchain yourself, such as by using [Order Watcher](https://0xproject.com/wiki#0x-OrderWatcher).
+
+# Misc.
+
+*   All requests and responses should be of **application/json** content type
+*   All token amounts are sent in amounts of the smallest level of precision (base units). (e.g if a token has 18 decimal places, selling 1 token would show up as selling `'1000000000000000000'` units by this API).
+*   All addresses are sent as lower-case (non-checksummed) Ethereum addresses with the `0x` prefix.
+*   All parameters are to be written in `lowerCamelCase`.

+# **get_order_config**
+
+> RelayerApiOrderConfigResponseSchema get_order_config(network_id=network_id, relayer_api_order_config_payload_schema=relayer_api_order_config_payload_schema)
+
+Relayers have full discretion over the orders that they are willing to host on their orderbooks (e.g what fees they charge, etc...). In order for traders to discover their requirements programmatically, they can send an incomplete order to this endpoint and receive the missing fields, specifc to that order. This gives relayers a large amount of flexibility to tailor fees to unique traders, trading pairs and volume amounts. Submit a partial order and receive information required to complete the order: `senderAddress`, `feeRecipientAddress`, `makerFee`, `takerFee`.

+# **get_orderbook**
+
+> RelayerApiOrderbookResponseSchema get_orderbook(base_asset_data, quote_asset_data, network_id=network_id, page=page, per_page=per_page)
+
+Retrieves the orderbook for a given asset pair. This endpoint should be [paginated](#section/Pagination). Bids will be sorted in descending order by price, and asks will be sorted in ascending order by price. Within the price sorted orders, the orders are further sorted by _taker fee price_ which is defined as the **takerFee** divided by **takerTokenAmount**. After _taker fee price_, orders are to be sorted by expiration in ascending order. The way pagination works for this endpoint is that the **page** and **perPage** query params apply to both `bids` and `asks` collections, and if `page` \* `perPage` > `total` for a certain collection, the `records` for that collection should just be empty.

+Retrieves a list of orders given query parameters. This endpoint should be [paginated](#section/Pagination). For querying an entire orderbook snapshot, the [orderbook endpoint](#operation/getOrderbook) is recommended. If both makerAssetData and takerAssetData are specified, returned orders will be sorted by price determined by (takerTokenAmount/makerTokenAmount) in ascending order. By default, orders returned by this endpoint are unsorted.
