README

This lib provides asserts against execution time and memory usage. It also provides a StopwatchListener based on the Stopwatch component of Symfony.

Installation

phpunit-profile-asserts is installable via Composer and should be added as a require-dev dependency:

composer require --dev jclaveau/phpunit-profile-asserts

Usage

Enable by adding the following code to your project's phpunit.xml file:

<phpunit bootstrap="vendor/autoload.php">
...
    <listeners>
        <listener class="JClaveau\PHPUnit\Listener\StopwatchListener" />
    </listeners>
</phpunit>

class SomeTestCase extends \PHPUnit_Framework_TestCase
{
    use \JClaveau\PHPUnit\Framework\UsageConstraintTrait; // adds the asserts methods

    /**
     */
    public function test_usages()
    {
        // ...

        $this->assertExecutionTimeBelow(1.5); // seconds
        $this->assertMemoryUsageBelow('1M');

        // This trait also provides two methods to help knowing the current
        // memory usage and duration
        $this->getMemoryUsage();
        $this->getExecutionTime();
    }

}

TODO

• Integrate SpeedTrap and adds MemoryTrap
• Investigate xhprof integration and asserts on number of calls / execution time of specific methods/functions
