Measuring Performance with Functional Tests: A Low-Effort Approach for High Impact

Proposal shows that adding zero-budget timestamps to existing functional tests produces actionable metrics: record start/end times, add granular stopwatches, use median not mean, and ignore failing runs. It uses CI runners, simple spreadsheets or Grafana, and Slack warnings (not build blocks). Practical rules include baseline recalibration, bracketing DB noise, run 3–5 iterations per case, weight critical tests into a performance score, and thresholds (example: 2.2s baseline → 2.64s warning). Real deployments catch 20% regressions and surface issues early.
