E2E Testing

When to Use

Activate this skill when:

• Writing E2E tests for complete user workflows (login, CRUD operations, multi-page flows)
• Creating critical path regression tests that validate the full stack
• Testing cross-browser compatibility (Chromium, Firefox, WebKit)
• Validating authentication flows end-to-end
• Testing file upload/download workflows
• Writing smoke tests for deployment verification

Do NOT use this skill for:

• React component unit tests (use react-testing-patterns)
• Python backend unit/integration tests (use pytest-patterns)
• TDD workflow enforcement (use tdd-workflow)
• API contract testing without a browser (use pytest-patterns with httpx)
