I've made some pretty significant changes to trial tonight [1][2]. They have been mainly focussed on refactoring to reduce repeated code, and on being able to extend trial. The tests work for me [3]. If they don't work for you, this is probably the reason. Please check for your platform as soon as possible and let the list know. I have tried hard to keep the functionality as close to the original as possible, but there have been some changes. Feel free to gaffle me and rollback the commit if this is a disastrous mistake. cheers, jml [1] http://twistedmatrix.com/users/jh.twistd/viewcvs/cgi/viewcvs.cgi/twisted/trial/unittest.py.diff?r1=1.63&r2=1.64&cvsroot=Twisted [2] http://twistedmatrix.com/users/jh.twistd/viewcvs/cgi/viewcvs.cgi/twisted/trial/unittest.py.diff?r1=1.64&r2=1.65&cvsroot=Twisted [3] In Python 2.2. In Python 2.1, testPackages in test_doc fails. I don't think this is my fault.
