SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

API testing infrastructure is often manual, flaky, and hard to scale across REST/GraphQL endpoints. This skill provides strategies and automation patterns to ensure reliable API behavior, contract conformity, and efficient test pipelines.

Core Features & Use Cases

  • Postman MCP integration for automated test execution and reporting.
  • Unit and integration tests for API endpoints with framework-specific examples.
  • Contract testing using OpenAPI/Pact patterns to validate service contracts.
  • CI/CD-ready test suites and workflows for reliable deployments.
  • Framework-agnostic guidance for REST and GraphQL APIs in production.

Quick Start

Set up your first API test suite and run it in your CI pipeline.
