TAP or Test Anything Protocol (a simple text-based interface between testing modules) is also available for PHPUnit. You can use it to show details with the flag
$ phpunit --tap
Which will result in an output like the following:
TAP version 13 ok 1 - newArrayIsEmptyTest(ArrayTest) ok 2 - arrayContainsAnElementTest(ArrayTest) 1..2
This is especially usefull when you've got tests in your test run which were marked as RISKY. With this output you can find out which ones they are.
