Build Status


Booster is a set of tools that will make your PHP and/or Symfony tests run faster and use less memory.


The recommended way to install this library is through Composer:

$ composer require driebit/booster

This command requires you to have Composer installed globally, as explained in the installation chapter of the Composer documentation.


Null properties on tear down

Nulling class properties on test tear down helps reduce memory footprint and test runtime. For instance when using PHPUnit:

use Driebit\Booster\Cleaner;

class MyTest extends \PHPUnit_Framework_TestCase
    // tests here...

    protected function tearDown()
        // tear down actions here...

        $cleaner = new Cleaner();

Or using the trait:

use Driebit\Booster\Phpunit\NullOnTearDownTrait;

class MyTest extends \PHPUnit_Framework_TestCase
    use NullOnTearDownTrait;

Disable debug mode after first kernel initialization

When running functional Symfony tests, you will probably be creating the service container many times. If debug mode is enabled, Symfony will check whether any resources have changed during each container initialization. By disabling debug mode, you wil be using a cached container in your tests.

Use the trait from your AppKernel:

use Driebit\Booster\Symfony\NoDebugTrait;

class AppKernel extends Kernel
    use NoDebugTrait;

    // ...
