How to run unittest discover from “python setup.py test”?

Question

I\'m trying to figure out how to get python setup.py test to run the equivalent of python -m unittest discover. I don\'t want to use a run_tests.p

Answer 1

This won't remove run_tests.py, but will make it work with setuptools. Add:

class Loader(unittest.TestLoader):
    def loadTestsFromNames(self, names, _=None):
        return self.discover(names[0])

Then in setup.py: (I assume you're doing something like setup(**config))

config = {
    ...
    'test_loader': 'run_tests:Loader',
    'test_suite': '.', # your start_dir for discover()
}

The only downside I see is it's bending the semantics of loadTestsFromNames, but the setuptools test command is the only consumer, and calls it in a specified way.
