1. execute "python -m unittest"
2. Result: 0 test found
3. Change file name from "aaaTest.py" to "test_aaa.py" 
4. execute "python -m unittest"
3. Result: Ran 1 tests in 000.0s

Module file MUST be named using the prefiux "test_".

The page "https://docs.python.org/3/library/unittest.html"
does not mention this MANDATORY rule.

I went to this conclusion because I readed the documentation without find any point about the naming convention of modules and than looking for this specific rule searching "test_" and "test_ " without any result.

Does this cover what you're looking for?

https://docs.python.org/3/library/unittest.html#cmdoption-unittest-discover-p

If you refer to the -p ("pattern" parameter) I think not.
I have my module named aaaTest.py.
I is is not mentioned that discover look for modules named "test_" for which reason I have to use a pattern?

If you refer to -s ("start-directory" parameter) same thing: for which reason I have to assume my aaaTest.py module is not recognized as a test?

This all seems to be covered in https://docs.python.org/3/library/unittest.html#test-discovery

$ cat aaaTest.py 
import unittest


class TestAAA(unittest.TestCase):

    def test_something(self):
        self.assertTrue(True)


if __name__ == '__main__':
    unittest.main()
$ python3 -m unittest discover -v -p "*Test.py"
test_something (aaaTest.TestAAA) ... ok

----------------------------------------------------------------------
Ran 1 test in 0.000s

OK



As the `--pattern` documentation says, the default pattern is "test*.py" which does not match "aaaTest.py".

You are right.

As the `--pattern` documentation says, the default pattern is "test*.py" which does not match "aaaTest.py".

I had looking for the wrong pattern.
