# solidity-coverage
|
|
|
|
Solidity code coverage plugin for [Hardhat](http://hardhat.org).
|
|
|
|
## What
|
|
|
|
![coverage example][22]
|
|
|
|
+ For more details about how it works and potential limitations, see [the accompanying article][16].
|
|
+ `solidity-coverage` is also [JoinColony/solcover][17]
|
|
|
|
|
|
## Installation
|
|
|
|
```bash
|
|
$ npm install --save-dev solidity-coverage
|
|
```
|
|
|
|
And add the following to your `hardhat.config.js`:
|
|
|
|
```js
|
|
require("solidity-coverage");
|
|
```
|
|
|
|
Or, if you are using TypeScript, add this to your hardhat.config.ts:
|
|
|
|
```ts
|
|
import "solidity-coverage"
|
|
```
|
|
|
|
## Tasks
|
|
|
|
This plugin implements a `coverage` task
|
|
|
|
```bash
|
|
npx hardhat coverage [options]
|
|
```
|
|
|
|
| Option <img width=200/> | Example <img width=750/>| Description <img width=1000/> |
|
|
|--------------|------------------------------------|--------------------------------|
|
|
| testfiles | `--testfiles "test/registry/*.ts"` | Test file(s) to run. (Globs must be enclosed by quotes.)|
|
|
| solcoverjs | `--solcoverjs ./../.solcover.js` | Relative path from working directory to config. Useful for monorepo packages that share settings. (Path must be "./" prefixed) |
|
|
| network | `--network development` | Run with a ganache client over http using network settings defined in `hardhat.config.js`. (Hardhat is the default network) |
|
|
|
|
|
|
## Configuration
|
|
|
|
Options can be specified in a `.solcover.js` config file located in the root directory of your project.
|
|
|
|
**Config Example:**
|
|
```javascript
|
|
module.exports = {
|
|
skipFiles: ['Routers/EtherRouter.sol']
|
|
};
|
|
```
|
|
|
|
| Option <img width=200/>| Type <img width=200/> | Default <img width=1300/> | Description <img width=800/> |
|
|
| ------ | ---- | ------- | ----------- |
|
|
| silent | *Boolean* | false | Suppress logging output |
|
|
| client | *Object* | undefined | *Ganache only*: Useful if you need a specific ganache version. An example value is: `require('ganache-cli')` |
|
|
| providerOptions | *Object* | `{ }` | *Ganache only*: [ganache-core options][1] |
|
|
| skipFiles | *Array* | `['Migrations.sol']` | Array of contracts or folders (with paths expressed relative to the `contracts` directory) that should be skipped when doing instrumentation. |
|
|
| istanbulFolder | *String* | `./coverage` | Folder location for Istanbul coverage reports. |
|
|
| istanbulReporter | *Array* | `['html', 'lcov', 'text', 'json']` | [Istanbul coverage reporters][2] |
|
|
| mocha | *Object* | `{ }` | [Mocha options][3] to merge into existing mocha config. `grep` and `invert` are useful for skipping certain tests under coverage using tags in the test descriptions.|
|
|
| onServerReady[<sup>*</sup>][14] | *Function* | | Hook run *after* server is launched, *before* the tests execute. Useful if you need to use the Oraclize bridge or have setup scripts which rely on the server's availability. [More...][23] |
|
|
| onCompileComplete[<sup>*</sup>][14] | *Function* | | Hook run *after* compilation completes, *before* tests are run. Useful if you have secondary compilation steps or need to modify built artifacts. [More...][23]|
|
|
| onTestsComplete[<sup>*</sup>][14] | *Function* | | Hook run *after* the tests complete, *before* Istanbul reports are generated. [More...][23]|
|
|
| onIstanbulComplete[<sup>*</sup>][14] | *Function* | | Hook run *after* the Istanbul reports are generated, *before* the ganache server is shut down. Useful if you need to clean resources up. [More...][23]|
|
|
|
|
[<sup>*</sup> Advanced use][14]
|
|
|
|
## Usage
|
|
|
|
+ Coverage runs tests a little more slowly.
|
|
+ Coverage uses the Hardhat network by default.
|
|
+ Coverage [distorts gas consumption][13]. Tests that check exact gas consumption should be [skipped][24].
|
|
+ :warning: Contracts are compiled **without optimization**. Please report unexpected compilation faults to [issue 417][25]
|
|
|
|
## Using with ganache
|
|
|
|
Begining with `v0.7.12`, this plugin runs directly on the Hardhat network by default (for speed).
|
|
|
|
If you want to use a ganache based http network, you can specify it by name using the `--network` cli option. The plugin will then launch its own coverage enabled ganache instance which can be configured in `.solcover.js` via the `providerOptions` key.
