Convenience plugin on top of mockito.
pip install pytest-mockito
After that the plugin is enabled by default.
The plugin provides fixtures for the main entrypoints of mockito which guarantee that you unstub() on teardown. Usage is very simple and straightforward:
def test_foo(when):
when(os.path).exists('/foo').thenReturn(False)
assert os.path.exists('/foo') # sic!
# will still unstub/unpatch bc pytest will run the teardown
For convenience verifyStubbedInvocationsAreUsed is called just before unstub. This should warn you when you setup stubs that you actually don't use.
You can also use a marker. usefixtures here will ensure an unstub at the end of each test, but does not actually inject the fixture:
import pytest
@pytest.mark.usefixtures('unstub')
class TestDog:
def test(self):
...
To mark all test cases at the module level:
pytestmark = pytest.mark.usefixtures('unstub')
All of the following fixtures just export the equivalent mockito function but unstub() on teardown. The exception here is expect which also calls verifyNoUnwantedInteractions():
