How can I mark tests as "long" and skip them?

I usually run my tests with tox which calls pytest. This setup works fine in many projects. In some projects, however, I have some tests which take long (several minutes). I don't want to run them every time. I would like to decorate the tests as long.

Something like this:

$ tox --skip-long

and

# core modules
import unittest

class Foo(unittest.TestCase):

    def test_bar(self):
        ...

    @long
    def test_long_bar(self):
        ...

How can I do this?
Solution

  • I found half of the answer here:

    @pytest.mark.long

    and execute

    pytest -v -m "not long"

    To run it on tox (source):

    tox -- -m "not long"

    The output then looks like this:

    ============================ 2 tests deselected ==================================
========== 20 passed, 2 deselected, 7 warnings in 151.93 seconds =================
