We've implemented a comprehensive testing and CI strategy, including a 7-job parallel CI pipeline architecture, a new end-to-end Playwright suite with accessibility auditing, and a robust backend contract testing framework using Hypothesis and Schemathesis. Frontend testing has also been leveled up with the introduction of Vitest, React Testing Library, and MSW for component-level verification. These changes significantly improve verification speed, reliability, and code coverage across the entire stack.
