assertEquals is an interface for running tests written with the Python standard library's unittest module. It used to be named testosterone. It delivers summary and detail reports on TestCases discovered in module-space, via both a command-line and a curses(3) interface. The interactive mode is the default, but it depends on the non-interactive mode. For debugging, static tracebacks and interactive Python debugger (Pdb) sessions are available in both scripted and interactive modes.
$ assertEquals [options] module
module is the dotted name of the module or package you wish to test. See the sections on scripted and interactive mode for more information.
