* Fix linting + `tests.challenges` imports

* Fix obscured duplicate test in test_url_validation.py

* Move VCR conftest to tests.vcr

* Specify tests to run & their order (unit -> integration -> challenges) in CI

* Fail Docker CI when tests fail

* Fix import & linting errors in tests

* Fix `get_text_summary`

* Fix linting errors

* Clean up pytest args in CI

* Remove bogus tests from GoCodeo
