API testing
API (Application Programming Interface) testing involves testing the interfaces exposed by the software to interact with other software components or services. It focuses on verifying that the APIs fulfill their functionality, return correct responses to different inputs, handle errors appropriately, and adhere to defined standards or specifications. API testing can be performed manually or automated using specialized testing tools.
