Key changes: - Run URL checks more frequently on every change. - Introduce environment variable to randomly select and limit URLs tested, this way the tests will provide quicker feedback on code changes. Other supporting changes: - Log more information about test before running the test to enable easier troubleshooting. - Move shuffle function for arrays for reusability and missing tests.
