So You're Automated...Now Let's Make It Fast!
summary
Practical recipe: make tests data independent so any test can run alone, convert long workflows into generated application state (a “magic URL” that injects cookies and items in under 3 seconds), split the CI into a serial stage and a parallel stage to cut build time (examples claim moving builds from ~45 minutes toward 4 minutes), remove third‑party widgets, replace static sleeps with dynamic waits, and use isolated guinea pig pages for heavy widgets.
