Stop hating your test suite!
summary
Tests become hated for three concrete reasons: they are slow, complicated to read, and unnecessary or flaky. Recommend focus on unit tests — 6,000 unit specs run in under a minute versus ~30 end-to-end tests taking ~15 minutes and a few integration suites taking minutes — and keep unit/integration/e2e in separate folders or repos. Use test doubles for units, follow AAA: setup, exercise, verify with blank lines, avoid clever DRY that creates mystery, and run e2e only for core flows on staging while running units locally on change.
