E2E Testing Patterns
Build reliable, fast, and maintainable end-to-end test suites that provide confidence to ship code quickly and catch regressions before users do.
Use this skill when
- Implementing end-to-end test automation
- Debugging flaky or unreliable tests
- Testing critical user workflows
- Setting up CI/CD test pipelines
- Testing across multiple browsers
- Validating accessibility requirements
- Testing responsive designs
- Establishing E2E testing standards
Do not use this skill when
- You only need unit or integration tests
- The environment cannot support stable UI automation
- You cannot provision safe test accounts or data
Instructions
- Identify critical user journeys and success criteria.
- Build stable selectors and test data strategies.
- Implement tests with retries, tracing, and isolation.
- Run in CI with parallelization and artifact capture.
Safety
- Avoid running destructive tests against production.
- Use dedicated test data and scrub sensitive output.
