roave/no-leaks

This library is a PHPUnit plugin that detects memory leaks in tested code or tests. It utilizes memory_get_usage() to make sure the code being executed properly cleans up after itself.

Installation

composer require --dev roave/no-leaks

Usage

vendor/bin/roave-no-leaks

If any memory leaks are detected, you should see an output like following:

Exception: The following test produced memory leaks:
 * My\Leaky\Test::testSomething
 * My\Leaky\Test::testSomethingElse

Configuration and Parameters

vendor/bin/roave-no-leaks supports all configuration parameters and console parameters of PHPUnit.

Known Issues

Please be aware that this is not a full substitute for PHPUnit:

• the output format is to be improved
• memory leak detection for scalar types and arrays is not reliable
• can fail depending on xdebug/phpdbg/php-sapi changes
