Pytest - how to order test execution in parametrized tests by parameter first

I have the following parametrized test:

import pytest
@pytest.mark.parametrize("url1", ["url0001", "url0002", "url0003"], indirect=False)
class Test01:
    def test01(self, url1):
        print(url1)
        assert url1 == f"{url1}"


    def test02(self, url1):
        print(url1)
        assert url1 == f"{url1}"

Result:

venv/test_url_fixt.py::Test01::test01[url0001] PASSED                    [ 16%]url0001

venv/test_url_fixt.py::Test01::test01[url0002] PASSED                    [ 33%]url0002

venv/test_url_fixt.py::Test01::test01[url0003] PASSED                    [ 50%]url0003

venv/test_url_fixt.py::Test01::test02[url0001] PASSED                    [ 66%]url0001

venv/test_url_fixt.py::Test01::test02[url0002] PASSED                    [ 83%]url0002

venv/test_url_fixt.py::Test01::test02[url0003] PASSED                    [100%]url0003

============================== 6 passed in 0.03s ==============================

Process finished with exit code 0

Info:
I just need to execute test01 with url1 = "url0001" and test02 with url1 = "url0001" first, then loop over all tests with the next parameter, e.g. test01 with url1 = "url0002", test02 with url1 = "url0002" and so on. I have the list of urls and want to execute properly set of tests with that list of urls.

Result of first test: empty suite with conftest in comments and I have not knowledge hot to run it separately (tried to learn, but too hard for me for now).

You can change the order of the items in the pytest_collection_modifyitems hook. If you put this in your conftest.py:

def pytest_collection_modifyitems(config, items):
    def param_part(item):
        # check for the wanted module and test class
        if item.nodeid.startswith("test_urls.py::TestSSL::"):
            # find the start of the parameter part in the nodeid
            index = item.nodeid.find('[')
            if index > 0:
                # sort by parameter name
                return item.name[item.nodeid.index('['):]

        # for all other cases, sort by node id as usual
        return item.nodeid

    # re-order the items using the param_part function as key
    items[:] = sorted(items, key=param_part)

Here is the output of pytest -vv for your example:

================================================= test session starts =================================================
...
collected 6 items

test_paramtrize_order.py::Test01::test01[url0001] PASSED                                                         [ 16%]

================================================== 6 passed in 0.09s ==================================================

This will change the order only for the parametrized tests in the module test_urls.py and the class TestSSL. If you want to have this for more or all parametrized tests, you can adapt or remove the check in param_part.
