How to conditionally skip a test in python

Question

I would like to skip some test functions when a condition is met, for example:

@skip_unless(condition)
def test_method(self):
    ...

Here I expect the test method to be reported as skipped if condition evaluated to true. I was able to do this with some effort with nose, but I would like to see if it is possible in nose2.

Related question describes a method for skipping all tests in nose2.

Answer 1

Generic Solution:

You can use unittest skip conditions which will work with nosetests, nose2 and pytest. There are two options:

class TestTheTest(unittest.TestCase):
    @unittest.skipIf(condition, reason)
    def test_that_runs_when_condition_false(self):
        assert 1 == 1

    @unittest.skipUnless(condition, reason)
    def test_that_runs_when_condition_true(self):
        assert 1 == 1

Pytest

Using pytest framework:

@pytest.mark.skipif(condition, reason)
def test_that_runs_when_condition_false():
    assert 1 == 1
