Maybe https://pypi.python.org/pypi/hypothesis is a better fit for this
than parametrization. At first it might seem a bit foreign (it felt so
to me), but it allows you to test in very interesting ways and to find
corner cases quickly. Just testing all the keys is pretty boring and
most likely won't lead to errors, so it's pretty much a waste of your
time and CPU time.

Hi,
Thank you for this great lib!
I have an app that takes a config file with key/value pairs, that I
would
like to test thoroughly, i.e all possible combinations of parameters
in the
config file. I thought about taking advantage of the fixture
parametrization functionality pytest provides, but not sure how... and
end
up with what I believe is a silly idea (please see example code
below). I
say silly because I will end up with a huge amount of
*.mark.parametrize()*
entries and the test case function with a number of arguments... Any
idea
on how to do this an elegant way?
*import* pytest
@pytest.mark.parametrize("key1", [0, 1, etc, etc])
@pytest.mark.parametrize("key2", [2, 3, etc, etc, etc])
@pytest.mark.parametrize("key3", [4, 5, etc, etc, etc, etc])
... # an infinitiy amount of @pytest.mark.parametrize("keyN", [bla,
bla,
bla])
*def* test_app_param_combination(key1, key2, key3, ....)
# implementation of the test
# run app with combination of key/value pair and check exit code
*assert* app_exit_code == 0
Many thanks
Go
