Symfony : automated run phpunit tests

i wrote some tests with the help of the symfony book : http://ift.tt/1O0nMEG my tests work fine and i really like them. Now i want to run these tests automated, like one time a day or every 48 h or something. Then i want to do something if the test result isnt right.

Is this possible in symfony, or do i have to write my own script with python or something wich runs my tests ?
