* Looponfail:
Run your tests repeatedly in a subprocess. After each run py.test waits
until a file in your project changes and then re-runs the previously
failing tests. This is repeated until all tests pass after which again a
full run is performed.
* Load-balancing:
if you have multiple CPUs or hosts you can use those for a combined test
run. This allows to speed up development or to use special resources of
remote machines.
* Multi-Platform coverage:
you can specify different Python interpreters or different platforms and
run tests in parallel on all of them.
