Can I import ward tests from another library?

[kajuberdut]

I have a number of libraries that share several hundred common tests. Is there any sane way for me to factor these tests into a separate python module and import them into each library?

[kajuberdut]

This might not be the greatest solution but I have found that it does work: Create the shared tests as a ward plugin:

import typing as t
from pathlib import Path

from my_library import module_containing_tests
from ward._collect import (
    get_info_for_modules,
    get_tests_in_modules,
    load_modules,
)
from ward.config import Config
from ward.hooks import hook
from ward.testing import Test


@hook
def preprocess_tests(config: Config, collected_tests t.List[Test]) -> None:
    paths = [Path(module_containing_tests.__file__)]
    mod_infos = get_info_for_modules(paths, ())
    modules = load_modules(mod_infos)
    if modules:
        collected_tests.extend(get_tests_in_modules(modules, True))

Leaving this issue open in case there is meaningful feedback on this approach.

What if you made a function in which the tests are defined (e.g. make_tests) and call it in each library you want to use the tests in?
