Profiling
In case you would like to perform php profiling of your tests you need to set variable ATHENA_ENABLE_PROFILER=1 before test execution.
XDebug Profiler is being enabled with following parameters:
profiler_enable=1
profiler_output_dir=/opt/tests
/opt/tests should be mapped to your tests directory so that after the test execution with profiler enabled you should find your profile information files in main test directory.
