Testing REST and GraphQL API endpoints involves validating HTTP methods, request payloads, and authentication mechanisms using tools like curl, Jest, pytest, and Postman for automated execution. This Skill handles functional validation, performance benchmarking, and security checks across both API types.

Testing a new POST endpoint requires validating the response status codes, schema, and data types returned by the server. You should also verify the request headers and body payload to ensure the endpoint correctly processes the input and returns the expected success code and data.

Performance benchmarking and security checks are fully supported during API testing. You can conduct load simulations to measure performance and run security checks to validate authentication mechanisms and identify potential vulnerabilities across your API endpoints.

This API testing approach works directly with curl, Jest, pytest, and Postman. It utilizes these tools to automate endpoint validation, execute functional tests, and simulate load for performance benchmarking across your REST and GraphQL services.

Validating HTTP methods and authentication mechanisms is best handled through comprehensive testing scenarios that check endpoint reliability and security. This approach specifically tests various HTTP methods, headers, and authentication flows to ensure correct API behavior.

API response schema validation fails when the returned data types or status codes do not match the expected testing parameters. You can resolve this by validating the response payloads and schemas against your defined HTTP methods and request bodies to identify mismatches.
