In pytest_generate_tests，how do I judge whether the current case needs to be run

[pyworker]

import pytest


class Plugin:
    def pytest_generate_tests(self, metafunc):
        print("*=" * 10, metafunc.definition.nodeid)


class TestCase:
    def test_1(self):
        assert 1 == 1

    def test_2(self):
        assert 2 == 2

    def test_3(self):
        assert 3 == 3


if __name__ == "__main__":
    case1 = "test.py::TestCase::test_1"
    pytest.main([case1], plugins=[Plugin()])

run results

I specify test_1 to run, but pytest_generate_tests has 3 cases.

test_1, test_2, and test_3 all appear in pytest_ generate_tests

Hi @hao1522 ,

Tour question is light on the details, so I'm guessing what you intend to do:

pytest_generate_tests is called for all the tests, it then should decide based on metafunc it should generate more tests.

Parametrization works like that: it checks for the parametrize mark, and generates new tests accordingly.

Hope this helps.
