```
$ npm install --save-dev solidity-coverage
```
### Run
Set a `coverage` network in truffle-config.js (see [Network Configuration](#network-configuration)) and then run:
```
$ npx solidity-coverage
```
### Usage notes:
+ For pragma solidity >=0.4.22 <0.6.0/Petersburg/Trufflev4andv5
+ For pragma solidity >=0.4.22 <0.6.0/Petersburg
+ Tests run more slowly while coverage is being generated.
+ Your contracts will be double-compiled and a (long) delay between compilation and
the beginning of test execution is possible if your contracts are large.
+ Truffle should be globallly installed in your environment.. If you prefer running truffle as
a local dependency, please see [this section](https://github.com/sc-forks/solidity-coverage/blob/master/docs/faq.md#running-truffle-as-a-local-dependency) of the FAQ.
+ If your suite uses native Solidity testing or accesses contracts via mocks stored in `tests/` (a la Zeppelin), coverage will trigger test errors because it can't control the way truffle compiles that folder. Mocks should be relocated to the root `contracts` directory. More on why this is necessary at issue [146](https://github.com/sc-forks/solidity-coverage/issues/146)
### Network Configuration
By default, this tool connects to a coverage-enabled fork of ganache-cli
called **testrpc-sc** on port 8555.
+ it's a dependency - there's nothing extra to download.
+ the solidity-coverage command launches it automatically in the background. (See [this section of the FAQ](https://github.com/sc-forks/solidity-coverage/blob/master/docs/faq.md#running-testrpc-sc-on-its-own) if you need to launch it separately yourself)
+ Contracts consume more gas while coverage is being generated.
+ solidity-coverage launches its own in-process ganache instance. You can
set its [options] via the `providerOptions` key in your .solcover.js
config file.
In `truffle-config.js`, add a coverage network following the example below.
### Truffle >= V5: setup and run
**Example**
Add "solidity-coverage" to your plugins array in `truffle-config.js`
| --file | --file="test/registry/*.js" | Filename or glob describing a subset of JS tests 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) |
| --version | | Version info |
| --help | | Usage notes |
### Config Options
Additional options can be specified in a `.solcover.js` config file located in
the root directory of your project.

| accounts | *Number* | 35 | Number of accounts to launch testrpc with. |
| port | *Number* | 8555 | Port to run testrpc on / have truffle connect to |
| norpc | *Boolean* | false | Prevent solidity-coverage from launching its own testrpc. Useful if you are managing a complex test suite with a [shell script](https://github.com/OpenZeppelin/openzeppelin-solidity/blob/ed872ca0a11c4926f8bb91dd103bea1378a3384c/scripts/coverage.sh) |
| testCommand | *String* | `truffle test` | Run an arbitrary test command. ex: `mocha --timeout 5000`. NB: Also set the `port` option to whatever your tests require (probably 8545). |
| testrpcOptions | *String* | `--port 8555` | options to append to a command line invocation of testrpc. NB: Using this overwrites the defaults so always specify a port in this string *and* in the `port` option |
| copyNodeModules | *Boolean* | false | :warning: **DEPRECATED** use `copyPackages` instead :warning: Copies `node_modules` into the coverage environment. May significantly increase the time for coverage to complete if enabled. Useful if your contracts import solidity files from an npm installed package (and your node_modules is small). |
| copyPackages | *Array* | `[]` | Copies specific `node_modules` packages into the coverage environment. May significantly reduce the time for coverage to complete compared to `copyNodeModules`. Useful if your contracts import solidity files from an npm installed package. |

| skipFiles | *Array* | `['Migrations.sol']` | Array of contracts or folders (with paths expressed relative to the `contracts` directory) that should be skipped when doing instrumentation. `Migrations.sol` is skipped by default, and does not need to be added to this configuration option if it is used. |
| deepSkip | boolean | false | Use this if instrumentation hangs on large, skipped files (like Oraclize). It's faster. |
| dir | *String* | `.` | Solidity-coverage copies all the assets in your root directory (except `node_modules`) to a special folder where it instruments the contracts and executes the tests. `dir` allows you to define a relative path from the root directory to those assets. Useful if your contracts & tests are within their own folder as part of a larger project.|
| istanbulReporter | *Array* | ['html', 'lcov', 'text'] | Coverage reporters for Istanbul. Optional reporter replaces the default reporters. |
