Component Testing -- Test component rendering with different prop combinations -- Verify event emissions -- Check accessibility attributes -- Test user interactions - -### 2. Mock Usage -- Use mocks for isolated unit testing -- Test component interfaces, not implementation details -- Create custom mocks for specific test scenarios -- Verify mock behavior matches real component - -### 3. Error Handling -- Test edge cases and error conditions -- Verify graceful degradation -- Test invalid prop combinations - -### 4.
