Question

I am struggling to run a single test method named testSaveAndDrop in the file escalation/EscalationGroupTest.php with phpunit. I tried

Answer 1

The following command runs the test on a single method:

phpunit --filter testSaveAndDrop EscalationGroupTest escalation/EscalationGroupTest.php

phpunit --filter methodName ClassName path/to/file.php

For newer versions of phpunit, it is just:

phpunit --filter methodName path/to/file.php
