Flipping the Testing Pyramid
summary
Argues for flipping the testing pyramid so widget tests become the central strategy, claiming they can cover up to 80% of a Flutter codebase and run fast (example full‑app widget test completes in about a second). Shows how to pump the whole app with fakes for ports, use the Robot pattern to collapse verbose tests into a few readable calls, and demonstrates the Spot Timeline/Spot package that produces local HTML timelines, chained selectors, annotated screenshots and faster, more actionable failure messages. Recommends avoiding brittle end‑to‑end emulators and keeping tests isolated and dependency‑injected.
