These tests use the Simyan requests caching for mocking tests, so tests will run quickly and not require credentials.
If your code adds a new URL to the cache, set the COMICVINE_API_KEY environment variable before running the test, and
it will be populated in the tests/cache.sqlite database.
At any point you should be able to delete the database, set any credentials, and run the full test suite to repopulate it (though some results might be different if any of the data has changed at Comic Vine).
