It would be better to not just check that there were _some_ request and that
they are not None (it seems that there can't be any None's there anyway unless
the testing code is broken) but to make sure that the code under test sent the
requests that we expect.

At this point we basically want to capture the existing behavior so what I would
do is dump `crowdin_mock_api.app.request_data` to a file, then look at it and
and for each request take a characteristic part of the URL and of the data. Then
make a test that checks that what we're getting is right by doing something
like:

    for (url, data), (expect_url, expect_data) in zip(request_log, expect_list):
        assert expect_url in url
        assert expect_data in data
