This package is already part of rector/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:

composer require rector/rector --dev

To add a set to your config, use Rector\PHPUnit\Set\PHPUnitSetList class and pick one of constants:

use Rector\Config\RectorConfig;
use Rector\PHPUnit\Set\PHPUnitSetList;

return RectorConfig::configure()
    ->withSets([
        PHPUnitSetList::COMPOSER_BASED,
    ]);

Rector is a tool that we develop 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.
