README

Rector rules for PestPHP to improve code quality and help with version upgrades.

Available Rules

See all available Pest rules here.

Installation

composer require --dev mrpunyapal/rector-pest

Available Rule Sets

Code Quality

Improve your Pest tests with better readability and expressiveness.

// rector.php
use RectorPest\Set\PestSetList;
use Rector\Config\RectorConfig;

return RectorConfig::configure()
    ->withPaths([
        __DIR__ . '/tests',
    ])
    ->withSets([
        PestSetList::PEST_CODE_QUALITY,
    ]);

Set	Description
PestSetList::PEST_CODE_QUALITY	Converts expect() assertions to use Pest's built-in matchers for better readability

Version Upgrade Sets

Use PestLevelSetList to automatically upgrade to a specific Pest version. Sets for higher versions include sets for lower versions.

// rector.php
use RectorPest\Set\PestLevelSetList;
use Rector\Config\RectorConfig;

return RectorConfig::configure()
    ->withPaths([
        __DIR__ . '/tests',
    ])
    ->withSets([
        PestLevelSetList::UP_TO_PEST_40,
    ]);

Set	Description
PestLevelSetList::UP_TO_PEST_30	Upgrade from Pest v2 to v3
PestLevelSetList::UP_TO_PEST_40	Upgrade from Pest v2/v3 to v4 (includes v3 changes)

Manual Version Configuration

Use PestSetList if you only want changes for a specific version:

// rector.php
use RectorPest\Set\PestSetList;
use Rector\Config\RectorConfig;

return RectorConfig::configure()
    ->withPaths([
        __DIR__ . '/tests',
    ])
    ->withSets([
        PestSetList::PEST_30, // Only v2→v3 changes
    ]);

Set	Description
PestSetList::PEST_30	Pest v2 → v3 migration rules
PestSetList::PEST_40	Pest v3 → v4 migration rules

Using Individual Rules

You can also use individual rules instead of sets:

// rector.php
use RectorPest\Rules\ChainExpectCallsRector;
use Rector\Config\RectorConfig;

return RectorConfig::configure()
    ->withPaths([
        __DIR__ . '/tests',
    ])
    ->withRules([
        ChainExpectCallsRector::class,
    ]);
