I've put together a brief discussion, with links to the source code, surrounding the demos I did at PyCon '07 during my testing tools talk. Here's a brief TOC:
# Demo 1: Testing CherryPy # Demo 2: Testing CherryPy without exec'ing a process # Demo 3: Basic code coverage analysis with figleaf # Demo 4: More interesting code coverage analysis with nose and figleafsections # Demo 5: Writing a simple twill extension to do form "fuzz" testing # Demo 6: Django fixtures for twill/wsgi_intercept # Demo 7: Recording and examining a Django session with scotch # Demo 8: Convert the Django session into a twill script # Demo 9: Replaying the Django session from the recording
