pytest-cfg-fetcher 0.1.1

Pass config options to your unit tests.

pytest-cfg-fetcher

Unit tests don't take arguments. Sometimes we like to pass an arg or two, e.g. you want to write test results to a file when running locally. This is a simple function to do that.

pytest-cfg-fetcher assumes you have a directory called _test-config/ in the same directory as your unit tests, e.g. under test/. The _test-config/ dir contains a config.json file/

_test-config/config.json contians minimally:

{
    "test_out_path": <path>
}

which is a local path where you might want to write output for tests.

The fetch_config() function takes a single argument, which should be the name of the test that calls it -- the return value is a dict object containing the test_out_path and whatever else you want to pass into your unit tests.

{
    "test_out_path": "test/_test-result",
    "my_test" {
        "my_test_bool_opt": true,
        "my_test_str_opt": "stringalingting"
    }
}

class Test(unittest.TestCase):

    def test_import(self):
        config = fetch_config("my_test")
        ...
        testy stuf
        ...
        test_result = "results of test"
        if config and config['my_test_bool_opt']:
            with open(f"{config['test_out_path']}/{config['my_test_str_opt']}.txt", "w+") as out:
                out.write(test_result)
