I believe that if you copy Lib/idlelib/idle_test/__init__.py to=20
tests/__main__.py and add
   import unittest; unittest.main()
then
   python -m tests
would run all your tests. Lib/idlelib/idle_test/README.py may help explai=
n.

Ditto for __main__.py files in each, so
   python -m tests.unit (functional)
will work.

'discover' is not needed for single files.  For instance,
   python -m unittest idlelib.idle_test.test_calltips
works for me. One can extend that to test cases and methods.
python -m unittest idlelib.idle_test.test_calltips.Get_entityTest
and
python -m unittest=20
idlelib.idle_test.test_calltips.Get_entityTest.test_bad_entity

If you add to each test_xyz.py file
   if __name__ =3D=3D '__main__':
     unittest.main(verbosity=3D2)  # example of adding fixed option
then
   python -m tests.unit.test_xyz
will run the tests in that file. (So does F5 in an Idle editor, which is =

how I run individual test files while editing. I copy the  boilerplate=20
from README.txt or an existing test_xyz.py file.)
