Test Specifications
Documentation that defines the requirements, procedures, and expected outcomes for testing software systems and APIs. Test specifications establish the criteria that implementations must satisfy, bridging the gap between product requirements and executable test cases. They include test plans, test case definitions, acceptance criteria, and conformance requirements. Effective use of this practice reduces bugs in production, supports contract testing, and enables a culture of quality-driven development aligned with OpenAPI, AsyncAPI, and JSON Schema standards.
