        To enable logging of test execution times, uncomment the following block in your phpunit.xml file.
        The first argument is the number of seconds (0 = off) that a test can run (threshold), before a warning is printed
        The second parameter is optional and specifies the path to the log file. Defaults to ./app/logs/test_{timestamp}.csv
