StoryText (formerly PyUseCase) is an unconventional GUI testing tool written in Python. It currently has mature support for PyGTK, beta status support for Java Swing, SWT/Eclipse RCP, and Tkinter, and very basic support for wxPython. Instead of recording GUI mechanics directly, it asks the user for descriptive names and hence builds up a "domain language" along with a "UI map file" that translates it into the current GUI layout. Instead of an "assertion" mechanism, it auto-generates a log of the GUI appearance and changes to it, so as to use that as a baseline for text-based testing, using e.g. TextTest. Instead of requiring the tester to add "wait" statements by hand, it includes support for instrumenting code so that "waits" can be recorded.
CaptureMock provides capture-replay mocking for Python, on the command line and with client-server communication. CaptureMock's approach is a so-called capture-replay approach. This means that when you 'record' your mock, CaptureMock will observe the interaction between your code and the subsystem you are mocking out, and record it in a text file in its own format. When you then run your test in 'replay mode', CaptureMock can play the role of the subsystem in question, and the real subsystem does not need to even be installed. You can then choose, each time you run your tests, whether you wish to have the real subsystems present and verify/recreate the captured mocks, or to rely on the mocks captured by a previous run. If you are running in 'replay mode' and CaptureMock does not receive the same calls as previously, it will fail the test, and suggest that you may want to recreate the mocks in record mode.
