API Schema Validation Testing
API Schema Validation Testing is a software testing practice that verifies whether API requests and responses conform to a defined schema or contract, such as OpenAPI, JSON Schema, or GraphQL schema definitions. It checks data structures, field types, required attributes, formats, and allowed values to detect contract violations between services and clients. Schema validation testing is commonly used in automated API testing pipelines to prevent integration failures and ensure backward compatibility.
