<Intro title="Measure your tests">
<IntroLead>
When it comes to writing smart contracts, testing is one of the most important steps of the process.
In order to quantify the robustness of your Solidity testing suite, you need to measure its code
coverage.

<Code language="js">
{`import { SolCompilerArtifactAdapter } from '@0x/sol-trace';
// Both artifactsDir and contractsDir are optional and will be fetched from compiler.json if not passed in
const artifactAdapter = new SolCompilerArtifactAdapter(artifactsDir, contractsDir);`}

Use <a href="#">ganache-cli</a> as a backing node.

Understand and use <a href="#">web3-provider-engine</a>.

<p>
Sol-cov is a subprovider that needs to be prepended to your <a href="#">provider engine</a>.
Depending on your project setup, you will need to use a specific ArtifactAdapter. Sol-cov ships
with the <InlineCode>SolCompilerArtifactAdapter</InlineCode> for use with{' '}
<a href="#">Sol-compiler</a> and <InlineCode>TruffleArtifactAdapter</InlineCode> for use with
the <a href="#">Truffle framework</a>. You can also write your own and support any artifact
format.

Now that we have an <InlineCode>artifactAdapter</InlineCode>, we can create a{' '}
<InlineCode>RevertTraceSubprovider</InlineCode> and append it to our provider engine.

const providerEngine = new ProviderEngine();
providerEngine.addProvider(revertTraceSubprovider);
