#PHPUnit

ParaTest allows for efficient parallel execution of PHPUnit tests without needing additional configuration. It supports running tests in parallel by TestCase or Test and combines code coverage outputs into one report. Compatible with only the latest versions of PHPUnit, ParaTest minimizes bugs by using internal classes. It also provides environmental variables for unique test identifiers and supports tools like PCOV and xDebug. The guide covers installation, PHPStorm integration setup, and troubleshooting for optimal testing performance.
