Unit tests are useless. Change my mind
summary
The talk argues that high-count unit tests often lock in implementation and become brittle, and instead promotes measurable, full‑stack end-to-end testing. It compares Cypress and Selenium, and demonstrates a practical setup using Docker, CircleCI and BrowserStack to parallelize browser E2E tests — rewriting a dashboard with 1,500 tests that ran ~50 minutes serially and dropped to ~3 minutes on 15 machines — to show reliability gains matter more than many shallow unit tests.
