What is API layer testing?
API testing is a type of software testing that involves testing application programming interfaces (APIs) directly and as part of integration testing to determine if they meet expectations for functionality, reliability, performance, and security. Since APIs lack a GUI, API testing is performed at the message layer.
What do you test in API testing?
API test actions
- Verify correct HTTP status code. For example, creating a resource should return 201 CREATED and unpermitted requests should return 403 FORBIDDEN, etc.
- Verify response payload.
- Verify response headers.
- Verify correct application state.
- Verify basic performance sanity.
Is SoapUI used for API testing?
SoapUI can be used for complete RESTful API and SOAP Web Service testing. You can do Functional Testing, Performance Testing, Interoperability Testing, Regression Testing and much more. You can even create REST specifications (WADL)from recorded communication.
What do you need to know about the API layer?
The API layer contains the business logic of an application – the rules of how users can interact with services, data, or functions of the app. Because the API or service layer directly touches both the data layer and the presentation layer, it presents the sweet spot of continuous testing for QA and Development teams.
Where does API testing take place in an application?
An API (application programming interface) is essentially the “middle man” of the layers and systems within an application or a software. API testing is performed at the message layer without GUI.
Which is the output of an API test?
The output in which the API returns is generally the pass or fail status, data, or a call to another API. For more accuracy and test coverage in API testing, data-driven testing should be performed. In order to test the API, the testers prefer automation testing when compared to manual testing.
How are API tests different from GUI tests?
In any other testing, standard user inputs and outputs are usually tested. API tests differ from GUI Tests as it doesn’t focus on the appearance and feel of the application but its focus is on the business logic layer of the software architecture. What are the types of API Testing?
