# Rector Rules for PHPUnit
See available [PHPUnit rules](https://getrector.com/find-rule?activeRectorSetGroup=phpunit)
## Install
This package is already part of [rector/rector](http://github.com/rectorphp/rector) package, so it works out of the box.
All you need to do is install the main package, and you're good to go:
```bash
composer require rector/rector --dev
```
## Use Sets
To add a set to your config, use `Rector\PHPUnit\Set\PHPUnitSetList` class and pick one of constants:
```php
use Rector\Config\RectorConfig;
use Rector\PHPUnit\Set\PHPUnitSetList;
return RectorConfig::configure()
->withSets([
PHPUnitSetList::PHPUNIT_90,
]);
```
## Learn Rector Faster
Rector is a tool that [we develop](https://getrector.org/) and share for free, so anyone can save hundreds of hours on refactoring. But not everyone has time to understand Rector and AST complexity. You have 2 ways to speed this process up:
* read a book - The Power of Automated Refactoring
* hire our experienced team to improve your code base
Both ways support us to and improve Rector in sustainable way by learning from practical projects.
