I would agree if the requirements for unit testing and integration/functional tests were so different. However, unittest provides most of the necessary infrastructure that is common to all of those kinds of testing. It's just that the latter kinds of tests also could use setUpClass/setUpModule. It would be a waste (and honestly kind of ridiculous) to force people to use a whole new framework (which would duplicate unittest in almost its entirety) for want of those two methods. -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco
