Hello list!

It took me a while to catch up with this but here I go.

Yes, I've got plenty options, and I showed them all in a lightning
talk I gave about test runners at PyCon Ar 2010.

Sadly, none of them provide my (ideal) test runner: a CLI colored
per-test output that accepts/handles unittest decorators.

* unit2 is colorless
* nose with rudolf will not provide a per test colored result
* py.test will no handle unittest skip/expectedFailure decorators
* trial won't handle the expectedFailure decorator (fails with
TypeError: addExpectedFailure() takes exactly 4 arguments (3 given))

So, I think I should try to add the coloured output option to unit2 as
a plugin. I'm not sure when I'll be able to do this in the short term,
but if I am, I'll let you all know.

Thanks a lot for all the answers!

Cheers, Natalia.
