How to get pytest-django to only run tests for a single app

Question

I was hoping that, by default, pytest-django would run the same tests that ./manage.py test does. Instead it runs all the Django tests and basically every python file it finds.

Here's my pytest.ini:

[pytest]
python_files=*.py
norecursedirs = .*, CVS, _darcs, {arch}, *.egg, django, south

I'd love to be able to do something like `py.test main.tests.TestAccess' to run a single test case. Any thoughts on how to accomplish this?

I attempted -k but, even with that option, I see many other files being run that I'm not interested in testing. Here's some output:

Answer 1

I see more options

1) use the path

 py.test <path_to_my_app>

py.test will search for test only in that subdir

or

 py.test <path_to_file>::<test>

will execute only

2) decorate each test with a specific marker

@pytest.mark.app1
def test_bla_bla():
    ....

and run with

    py.test -m app1

3) use -k passing the test funnction name

Answer 2

You can run a single test using the option -k.
