In order for it to gather these traces, you must add the `CoverageSubprovider` to the [ProviderEngine](https://github.com/MetaMask/provider-engine) instance you use when running your Solidity tests. If you're unfamiliar with ProviderEngine, please read the [Web3 Provider explained](https://0xproject.com/wiki#Web3-Provider-Explained) wiki article. - -The CoverageSubprovider eavesdrops on the `eth_sendTransaction` and `eth_call` RPC calls and collects traces after each call using `debug_traceTransaction`. `eth_call`'s' don't generate traces - so we take a snapshot, re-submit it as a transaction, get the trace and then revert the snapshot. - -Coverage subprovider needs some info about your contracts (`srcMap`, `bytecode`). It gets that info from your project's artifacts. Some frameworks have their own artifact format. Some artifact formats don't actually contain all the neccessary data. - -In order to use `CoverageSubprovider` with your favorite framework you need to pass an `artifactsAdapter` to it. - -### Sol-compiler - -If you are generating your artifacts with [@0xproject/sol-compiler](https://0xproject.com/docs/sol-compiler) you can use the `SolCompilerArtifactsAdapter` we've implemented for you. - -```typescript -import { SolCompilerArtifactsAdapter } from '@0xproject/sol-cov'; -const artifactsPath = 'src/artifacts'; -const contractsPath = 'src/contracts'; -const artifactsAdapter = new SolCompilerArtifactsAdapter(artifactsPath, contractsPath); -``` - -### Truffle - -If your project is using [Truffle](https://truffleframework.com/), we've written a `TruffleArtifactsAdapter`for you. - -```typescript -import { TruffleArtifactAdapter } from '@0xproject/sol-cov'; -const contractsPath = 'src/contracts'; -const artifactAdapter = new TruffleArtifactAdapter(contractsDir); -``` - -Because truffle artifacts don't have all the data we need - we actually will recompile your contracts under the hood. That's why you don't need to pass an `artifactsPath`. - -### Other framework/toolset - -You'll need to write your own artifacts adapter. It should extend `AbstractArtifactsAdapter`. -Look at the code of the two adapters above for examples. - -### Usage - -```typescript -import { CoverageSubprovider } from '@0xproject/sol-cov'; -import ProviderEngine = require('web3-provider-engine'); - -const provider = new ProviderEngine(); - -const artifactsPath = 'src/artifacts'; -const contractsPath = 'src/contracts'; -const networkId = 50; -// Some calls might not have `from` address specified. Nevertheless - transactions need to be submitted from an address with at least some funds. defaultFromAddress is the address that will be used to submit those calls as transactions from. -const defaultFromAddress = '0x5409ed021d9299bf6814279a6a1411a7e866a631'; -const isVerbose = true; -const coverageSubprovider = new CoverageSubprovider(artifactsAdapter, defaultFromAddress, isVerbose); - -provider.addProvider(coverageSubprovider); -``` - -After your test suite is complete (e.g in the Mocha global `after` hook), you'll need to call: - -```typescript -await coverageSubprovider.writeCoverageAsync(); -``` - -This will create a `coverage.json` file in a `coverage` directory. This file has an [Istanbul format](https://github.com/gotwarlost/istanbul/blob/master/coverage.json.md) - so you can use it with any of the existing Istanbul reporters. -- cgit v1.2.3
