5 Testing Practices you should have in your CI / CD Pipeline

A frontend engineer shares five testing practices worth integrating into CI/CD pipelines, drawn from real experience at a company with no QA engineers. The five practices covered are: Performance Tests (using Lighthouse CI to guard Core Web Vitals), Mutation Tests (to validate unit test quality by intentionally breaking code), Visual Tests (screenshot comparisons to catch unintended CSS regressions), Feature/Component Tests (browser-based component testing as a replacement for integration tests), and Contract Tests (using PACT to ensure API responses match frontend expectations and prevent outages caused by microservice mismatches).
