PHPUnit Accelerator

Inspired by Kris Wallsmith faster PHPUnit article, we've created a PHPUnit test listener that speeds up PHPUnit tests about 20% by freeing memory.

Installation

To install this library, run the command below and you will get the latest version

composer require mybuilder/phpunit-accelerator --dev

Usage

Just add to your phpunit.xml configuration

<phpunit>
    <listeners>
        <listener class="\MyBuilder\PhpunitAccelerator\TestListener"/>
    </listeners>
</phpunit>

Ignoring Tests

Sometimes it is necessary to ignore specific tests, where freeing their properties is undesired. For this use case, you have the ability to extend the behaviour of the listener by implementing the IgnoreTestPolicy interface.

As an example, if we hypothetically wanted to ignore all tests which include "Legacy" in their test filename, we could create a custom ignore policy as follows

<?php

use MyBuilder\PhpunitAccelerator\IgnoreTestPolicy;

class IgnoreLegacyTestPolicy implements IgnoreTestPolicy {
    public function shouldIgnore(\ReflectionObject $testReflection) {
        return strpos($testReflection->getFilename(), 'Legacy') !== false;
    }
}

And pass it to the constructor of our test listener in phpunit.xml configuration

<phpunit>
    <listeners>
        <listener class="\MyBuilder\PhpunitAccelerator\TestListener">
            <arguments>
                <object class="\IgnoreLegacyTestPolicy"/>
            </arguments>
        </listener>
    </listeners>
</phpunit>
