Lousy is a test runner which integrates with the project bug tracker to keep track of which tests failed when and why. This is a useful feature for intermittent failures or failures which reappear. Just because a particular test fails doesn't mean that it is failing for the same reason it failed last time. Lousy provides the infrastructure necessary to narrow down failure causes to particular bugs, record that data in the bug tracker and create new bugs in the bug tracker for new failures.
