What versions of python are you aiming at? Is Arches still trying to maintain compatibility with 2.6? And is python 3 compatibility wanted? Might influence your choice of testing framework.
If you're trying to maintain compatibility with 2.6, look into the unittest2 library. I believe it brings python 2.6's unittest module up to the level of python 2.7's library. I've never used py.test but it looks rather nice. We normally use the standard unittest library, nose as a testrunner and coverage for the coverage report. I believe nose can also run py.test tests. And py.test seems to be able to run nose test suites. So, it all seems to be rather connected. When constructing your testsuite, it's a good idea to try and write as many unit tests as possible without needing a database. These can run a whole lot faster than unit tests requiring a database. Normally your testdatabase will be constructed and torn down for every single unit test. As soon as your database is anything non-trivial, this slows your testsuite down to a crawl. We currently solved this in one of our applications by only setting up and tearing down the database once per testsuite. This is using the Pyramid framework (not Django). What we did, was to setup the database at the beginning of the module, start a database transaction, run the unit test, rollback the transaction, start a new transaction, run the second test, rollback the transaction, etc... At the end of the module, the entire database is torn down. The next module does the same thing. The inspiration for this came from this blog post: http://sontek.net/blog/detail/writing-tests-for-pyramid-and-sqlalchemy. It's about Pyramid (and uses py.test), but I think the principal should be applicable to other frameworks as well. Django might have something for this as well.

Yes, they are both the same. I also just saw this: https://pypi.python.org/pypi/pytest-django/ One thing caught my eye when they describe the advantages of pytest which was "Database re-use: no need to re-create the test database for every test run." That may be something we might have to look out for. Interesting. I have not worked with py.test yet. The documentation is pretty convincing but I think we better have a look at these[1][2] comparisons as well. (Also note that these discussions are quite old and probably obsolete). Also, I found[3][4][5] to be very comprehensive articles on Python testing frameworks. So this might be a good starting point to decide where we will be going with our testing work-flow.
