Python: Running all unit tests inside a package

Question

I'm trying to hack my through an open source python project (namely: jinja2),

When I say "I'm hacking my way through", I mean I don't really know what I'm doing, so I want to run unittests whenever I change something to make sure I'm not breaking something major!

There's a package full of unit tests (if you want to have a look, it's here). Basically it's a folder full of python files with the name "test_xxxxxx.py"

How do I run all of these tests in one command?

Answer 1

It looks like Jinja uses the py.test testing tool. If so you can run all tests by just running py.test from within the tests subdirectory.

Answer 2

Try to 'walk' through the directories and import all from files like "test_xxxxxx.py", then call unittest.main()

Answer 3

You could also take a look at nose too. It's supposed to be a py.test evolution.

Answer 4

Watch out for "test.py" in the Jinja2 package! -- Those are not unit tests! That is a set of utility functions for checking attributes, etc. My testing package is assuming that they are unit tests because of the name "test" -- and returning strange messages.
