Testing Strategy

anthropics/knowledge-work-pluginsOfficial

When someone asks "how should we test this" or "what tests do we need", this skill kicks in to help you think through test architecture instead of just writing individual tests. It pushes you toward the testing pyramid, suggests appropriate test types based on what you're building (APIs get contract tests, data pipelines get idempotency checks, frontend gets accessibility coverage), and helps identify gaps in existing suites. The real value is in forcing the conversation about what actually matters to test versus what's just coverage theater. It won't write your tests for you, but it will give you a structured plan with coverage targets and example cases so you're not just throwing assertions at the wall.

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
