unittest vs py.test?

[Grig Gheorghiu]

In my mind, practicing TDD is what matters most. Which framework you
choose is a function of your actual needs. The fact that there are 3 of
them doesn't really bother me. I think it's better to have a choice
from a small number of frameworks rather than have no choice or have a
single choice that might not be the best for your specific environment
-- provided of course that this doesn't evolve into a PyWebOff-like
nightmare :-)
