Suppose you have a python package named A with the following directory structure
A
├── B.py
└── __init__.py
where __init__.py is empty and the content of B.py is given by
def test_B():
assert False
Running nose on the simple package above misses the test
$ nosetests A
----------------------------------------------------------------------
Ran 0 tests in 0.000s
OK
One has to run
$ nosetests A/B.py
in order to catch the test, but that quickly becomes unwieldy if one has a complicated submodule structure inside A.
How can one make nose run all functions starting with 'test' in package A without having to specify every single file in which they occur?
Use the --all-modules flag:
$ nosetests A --all-modules
