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](LINK) you can use the `SolCompilerArtifactsAdapter` we've implemented for you.
```typescript
<<<<<<< HEAD
import { CoverageSubprovider } from '@0xproject/sol-cov';
=======
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](LINK), 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');
>>>>>>> Improve sol-cov docs
const provider = new ProviderEngine();

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 the `coverage` directory. This file has an [Istanbul format](https://github.com/gotwarlost/istanbul/blob/master/coverage.json.md) - so you can use any of the existing Instanbul reporters.
