Testing Strategy

Design effective testing strategies balancing coverage, speed, and maintenance.

Testing Pyramid

        /  E2E  \         Few, slow, high confidence
       / Integration \     Some, medium speed
      /    Unit Tests  \   Many, fast, focused

Strategy by Component Type

• API endpoints: Unit tests for business logic, integration tests for HTTP layer, contract tests for consumers
• Data pipelines: Input validation, transformation correctness, idempotency tests
• Frontend: Component tests, interaction tests, visual regression, accessibility
• Infrastructure: Smoke tests, chaos engineering, load tests
