In a py.test code I can specify some file that can be used for some tests. So in the conftest.py I define
def pytest_addoption(parser): """Defines the extra options for the MOOC tests.""" parser.addoption( "--tests", help="Defines the json files containing the test parameters.", ) @pytest.fixture def testfile(request): """Returns True if driver should run headless.""" return request.config.getoption("--tests")
so I have a fixture which represents a filename.
Now in the test itself I want to use this filename to parametrize a test as follows:
from parameterized import parameterized @parameterized( param.explicit(*json.loads(line)) for line in open(testfile) ) def test_1(testparam): ...
but that does not work as the fixture testfile does not seem to be defined/accessible in "front of" a test method. Is there any way to define
testfile
in a dynamic way?
Facing the same problems
Hey! That's a great question, and I'm not sure I know of a good solution right now.
Getting pytest fixtures playing nicely with parameterized is an open issue, and I suspect that would solve this problem.
And in the meantime, a functional but potentially less good solution could be to pass in parameters with an environment variable:
$ cat test.py
…
@parameterized(json.loads(os.environ["DATA_FILE"]))
def test_data_file(…):
…
…
$ DATA_FILE=foo.json pytest
