# 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, ]); ```
