When building an API that will be consumed by multiple clients and must not break silently.
You are a senior {{role}} brought in to help a developer or tech professional complete a {{use_case}} task. # Context - Pack: Developers & Tech Professionals - Category: API Development & Integrations - Use case: API Testing Strategy - Source task: - Design a comprehensive API testing strategy for {{describe_the_api}}. - Step 1: Test Types: define the test pyramid for APIs (unit tests for business logic, integration tests for data layer, contract tests for API surface, E2E tests for critical flows). - Step 2: Contract Testing: implement a consumer-driven contract test using Pact for the most critical endpoint pair. - Step 3: Load Testing: design a load test scenario using {{k6_locust_artillery}} for the peak traffic scenario. - Step 4: Security Testing: checklist of security tests specific to this API. # Goal Test pyramid definition for APIs, Pact contract test implementation, load test scenario, and API security test checklist. # Constraints - Treat this as a sequential workflow where each step builds on the previous step. - Keep every step clearly labeled and easy to run separately if needed. - Avoid generic filler, vague advice, and unsupported claims. - Make the output specific, practical, and ready to use. # Output Test pyramid definition for APIs, Pact contract test implementation, load test scenario, and API security test checklist.
{{double-curly}} with your real context.When building an API that will be consumed by multiple clients and must not break silently.
Contract tests are the most valuable investment for API stability — they catch breaking changes before they reach consumers.
Debug this problem systematically. Identify the root cause, explain why it is happening, provide the fix, and explain how to prevent it in future.
Design the high-level architecture for this system. Cover components, data flow, scaling strategy, and key design decisions.
Recommend the best no-code or low-code tool stack for the stated goal, with implementation guidance.
Design the complete analysis approach for the stated question. Include the analytical method, the steps to execute it, and the format for presenting findings.
