pytest.mark.parametrize is broken

[frafra]

pytest.mark.parametrize works with pytest:

import pytest
class TestParametrized:
    @pytest.mark.parametrize('value', [0, 1])
    def test(self, value):
        pass

...but it doesn't with seleniumbase:

from seleniumbase import BaseCase
import pytest
class TestParametrized(BaseCase):
    @pytest.mark.parametrize('value', [0, 1])
    def test(self, value):
        pass

Error message:

[...]
                with outcome.testPartExecutor(self, isTest=True):
>                   testMethod()
E                   TypeError: test() missing 1 required positional argument: 'value'

@frafra See https://github.com/seleniumbase/SeleniumBase/blob/master/examples/parameterized_test.py which lets you parameterize tests with the “parameterized” package.

@frafra To invoke pytest fixtures directly, such as pytest.mark.parameterize, see this example:

import pytest


@pytest.mark.parametrize('value', ["pytest", "selenium"])
def test_sb_fixture_with_no_class(sb, value):
    sb.open("https://google.com/ncr")
    sb.update_text('input[title="Search"]', value + '\n')
    sb.assert_text(value, "div#center_col")


class Test_SB_Fixture():
    @pytest.mark.parametrize('value', ["pytest", "selenium"])
    def test_sb_fixture_inside_class(self, sb, value):
        sb.open("https://google.com/ncr")
        sb.update_text('input[title="Search"]', value + '\n')
        sb.assert_text(value, "div#center_col")

Its uses seleniumbase as a fixture to allow the use of any pytest fixture. (sb fixture)

Here's an example of correct pytest.mark.parameterize usage with SeleniumBase:

Thank you :-) but pytest.mark.parameterize does not work with Seleniumbase if you decorate a function inside a class, as my first comment tried to show.

@frafra That's due to a bug with pytest itself. See pytest-dev/pytest#541 I've created a few different workarounds: 1, by using the parameterized package; and 2, by creating the sb fixture for seleniumbase, which passes the unittest.TestCase class as a fixture into pytest tests. Without these workarounds, the issue needs to be corrected on the pytestside, and the maintainers of that probably could fix it if they look how I passed all of seleniumbase's unittest.TestCase methods through the fixture, instead of a direct class import.
