API Testing
An application programming interface (API) is a type of programming interface. API can be thought of as a bridge between two software systems that allows them to communicate. API testing entails evaluating application programming interfaces (APIs) both independently and as part of integration testing to see if they fulfill functionality, reliability, performance, and security requirements.
- API tests are only run when the build is complete.
- As the user interface with which an end-user will interact, API testing must represent the system as a whole.
- API testing is a type of black-box testing that focuses solely on the system under the test’s ultimate output.
