Testing in Production – dangerous, scary or better?
summary
Argues that running browser tests against live systems is practical not theoretical and shows how Selenium webdriver plus a Scala test runner becomes continuous monitoring, running 3200 tests a day; hides test content by tagging with production monitoring tag and filters pageview and syndication noise; pushes test robustness from ~95% to ~99.5–99.7% so alerts use tolerance windows instead of flaky retries; delivers an always-on dashboard that catches real production faults and indeed works.
