Description

Key MomentsDefining end-to-end tests: The hosts clarify that true business end-to-end flows go far beyond what mobile teams can actually test, so the “ends” are usually artificially limited.How they’re supposed to work: Tools like Detox or Maestro automate UI taps through accessibility labels, running flows on simulators or devices.Why they fail: End-to-end tests are flaky, slow, expensive to run, and often break due to infrastructure issues rather than app logic.High maintenance cost: Teams commonly spend 10–20% of engineering time on setup, debugging, and unreliable failures—often with little real value.What they can be good for: Tracking performance (e.g., startup time) and generating automated screenshots for design review.Why they don’t catch UI issues: Tests only verify tappability and flow—not layout, appearance, or subtle bugs.If you must use them: Cache aggressively, learn your tool deeply, and write tests optimized for reliability, not full coverage.Big picture: For most teams, end-to-end tests provide poor ROI; solid architecture and good communication usually solve the real problems better. 👋 Visit us on https://brainsandbeards.com/
