Flaky, Fragile, and Forgotten: The Fall of a Test Automation Project
summary
A real postmortem of a repo that becomes the team blocker: flaky UI locators break after one library change, a CI suite grows to 500 tests and a 4-hour pipeline, Selenium + WebDriverIO + BrowserStack adds latency, and parallel runs expose hidden test dependencies. Ten root causes map to concrete fixes: respect the test pyramid, remove duplicate setup, stop over‑abstraction, improve reporting and retention, and switch to Playwright migration plus AI-assisted test generation and rule checks to keep PRs stable.
