The pylib library features the popular py.test command line tool for rapidly writing and running tests in Python and py.execnet, a new way to do ad-hoc distribution of Python code to remote processes. py.test runs well on Linux, Windows, and OSX using Python 2.4 through to 2.6. It can distribute a single test run to multiple machines. It is used in many projects, ranging from running tens of thousands of tests integrated with buildbot to a few inlined tests on a command line script.
