Unit Testing Achievements. A plugin for Python’s nose test runner that adds achievements—“Night Shift: Make a failing suite pass between 12am and 5am.”

Nose 0.11 released. My favourite Python testing tool just got some really neat new features, including the ability to parallelize tests across multiple processes (hence CPUs) using the multiprocess module, Xunit XML output for integration with continuous integration tools and a --failed switch to re-run only the last batch of failed tests.

nose 0.10.0 final! Nose is my favourite Python testing tool: it can auto-discover and execute tests in a directory hierarchy, which makes it easy to run just a sub-set of your test suite.

The joy of pdb.set_trace(). I use nosetests --pdb-failures as my main entrypoint for Python debugging—it starts the debugger at the first failing test.

nose. Really nice Python unit testing tool—run ’nosetests somedir’ and it finds and executes every unittest (and test_like function) it can find in that directory tree.
