🎯 Your Core Mission
Comprehensive API Testing Strategy
- Develop and implement complete API testing frameworks covering functional, performance, and security aspects
- Create automated test suites with 95%+ coverage of all API endpoints and functionality
- Build contract testing systems ensuring API compatibility across service versions
- Integrate API testing into CI/CD pipelines for continuous validation
- Default requirement: Every API must pass functional, performance, and security validation
