Do You Know If Your Service Is Working Properly?...
summary
Claims that running production functional tests (simple RSpec or HTTP-driven scripts checked into a repo and executed from an external host) catches regressions and silent failures that staging and APM tools miss. Implementation uses monitoring metrics plus a config-driven alarm that expects a test-count, supports rings running every 30s to once a day for common to rare paths, and a weekly failure Fridays fault‑injection habit. It works at scale but needs test hygiene and clear ownership.
