[ADP-44] API Testing

Guidelines

MUST ensure that tests cover all API endpoints, request methods, and response codes.
MUST verify that the API operates according to specifications and expected behavior.
MUST check for common security vulnerabilities in the API, such as authentication, authorization, and data validation issues.
MUST assess the API's response time and throughput under various load conditions.
MUST verify the API's behavior under different network conditions and error scenarios.
MUST test the API's integration with other systems and services.
MUST ensure the accuracy and completeness of API documentation.
MUST verify that the API correctly handles various input data types and edge cases.
MUST ensure proper implementation of API version control and maintain backward compatibility when necessary.

SHOULD use automated testing tools and frameworks to improve testing efficiency and coverage.
SHOULD integrate API testing into the CI/CD process to identify and resolve issues early.
SHOULD use mock services to test API dependencies and edge cases.
MUST conduct regular security audits and penetration testing.
SHOULD monitor API performance and usage in the production environment to identify potential issues.
SHOULD implement contract testing to ensure that API consumers and providers adhere to agreed-upon interfaces.
SHOULD use data-driven testing methods to efficiently cover a wide range of scenarios.

MUST track and analyze key testing metrics, such as test coverage, pass/fail rates, and performance benchmarks.
SHOULD regularly generate API testing results and trend reports to inform stakeholders and guide improvement efforts.
MUST maintain a centralized repository of test results for historical analysis and compliance purposes.
