# PHPUnit TIA

A PHPUnit extension for Test Impact Analysis (TIA), which runs only the tests that relate to the files you changed.

It is a port of the TIA engine from Pest. Tests that your change does not affect are marked as skipped. It needs PHPUnit 13, PHP 8.4 and a coverage driver (pcov or Xdebug).
