testresources http://www.robertcollins.net/unittest/testresources/ purpose appears to be to manage the resources used by a test suite.

Adding this resource management context extends the Test Suite to optimize tests around the resources. This can reshuffle the TestCases to minimize SetUp's. This can be useful in contexts where …

SubUnit's http://www.robertcollins.net/unittest/subunit/ purpose appears to be to manage testing via subprocesses.

Consequently, it can run external tests not in Python, it can fork a subprocess to manage the Fixture in an isolated process.

Adding this subprocess execution context extends the Test Runner implementation of the …

I'll examine these in light of the Beck Unit Test design patterns to provide a little more detail on what they really do …
