## Code coverage for Solidity testing
|
|
![coverage example][22]
|
|
|
|
+ For more details about what this is, how it works and potential limitations,
|
|
see [the accompanying article][16].
|
|
+ `solidity-coverage` is [Solcover][17]
|
|
|
|
## Install
|
|
```
|
|
$ npm install --save-dev solidity-coverage
|
|
```
|
|
|
|
**Resources**:
|
|
+ [0.7.0 release notes][31]
|
|
+ [A guide][29] to upgrading from 0.6.x to 0.7.x
|
|
+ [0.6.3 docs][30]
|
|
|
|
### Truffle V5
|
|
|
|
**Add** this package to your plugins array in `truffle-config.js` ([Truffle docs][27])
|
|
```javascript
|
|
module.exports = {
|
|
networks: {...},
|
|
plugins: ["solidity-coverage"]
|
|
}
|
|
```
|
|
**Run**
|
|
```
|
|
truffle run coverage [command-options]
|
|
```
|
|
|
|
### Buidler
|
|
|
|
**Add** the plugin in `buidler.config.js` ([Buidler docs][26])
|
|
```javascript
|
|
usePlugin('solidity-coverage')
|
|
|
|
module.exports = {
|
|
networks: {...},
|
|
}
|
|
```
|
|
**Run**
|
|
```
|
|
npx buidler coverage [command-options]
|
|
```
|
|
|
|
**Buidler Project Examples:**
|
|
|
|
+ Simple: [buidler-metacoin][32]
|
|
+ More complex: [MolochDao/moloch][33]
|
|
|
|
|
|
## Usage notes:
|
|
+ Coverage runs tests a little more slowly.
|
|
+ Coverage launches its own in-process ganache server.
|
|
+ You can set [ganache options][1] using the `providerOptions` key in your `.solcover.js` [config][15].
|
|
+ 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]
|
|
|
|
## Command Options
|
|
| Option <img width=200/> | Example <img width=750/>| Description <img width=1000/> |
|
|
|--------------|------------------------------------|--------------------------------|
|
|
| file | `--file="test/registry/*.js"` | (Truffle) Filename or glob describing a subset of JS tests to run. (Globs must be enclosed by quotes.)|
|
|
| testfiles | `--testfiles test/file.js` | (Buidler) JS test file(s) to run.|
|
|
| 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` | Use network settings defined in the Truffle or Buidler config |
|
|
| temp[<sup>*</sup>][14] | `--temp build` | :warning: **Caution** :warning: Path to a *disposable* folder to store compilation artifacts in. Useful when your test setup scripts include hard-coded paths to a build directory. [More...][14] |
|
|
|
|
[<sup>*</sup> Advanced use][14]
|
|
|
|
## Config Options
|
|
|
|
Additional options can be specified in a `.solcover.js` config file located in the root directory
|
|
of your project.
|
|
|
|
**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* | `require("ganache-core")` | Useful if you need a specific ganache version. |
|
|
| providerOptions | *Object* | `{ }` | [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]|
|
