Application Programming Interface, or API, is a shorthand for that. The intermediary layer between the presentation (UI) and the database layer in the development of software applications (apps) is the API. APIs allow data and communication to flow across software systems. API testing is a kind of software testing that examines the APIs’ functionality, dependability, performance, and security. API testing, which is a type of integration testing, quickly and efficiently tests the build architecture’s logic.
Here are some pointers users should keep in mind while conducting their API testing with API Tester before setting out on their own:
- First, test for normal or anticipated outcomes.
- A set of API load tests will put the system under stress.
- Make sure the user is aware of the API failure. Make sure the API always fails gracefully and consistently.
- Sort test cases according to test type.
- Prioritize API function calls to make it simple and quick for testers to test.
- Keep the tests as separated as user can from as many variables as you can.
- Throw as many demands as possible at it to see how it responds to unforeseen issues and overload.
Where Are API Tests Conducted?
A typical app has three layers: the business layer, the presentation layer, and the database layer for modelling and manipulating data. The most important layer, business, where all transactions between the user interface and database layers take place, is where API testing is carried out.
Advantages Of Testing Apis:
- Any language can be used for test automation because data is shared via the XML and JSON standards. Since XML and JSON often contain structured data, the verification process is quick and reliable.
- Before performing GUI testing, the app can conduct GUI-independent API testing. Early testing translates into early feedback and increased team output. The main features of the app can be tested to find minor issues and assess the build’s strengths.
- Since most APIs and web services contain specifications, users can develop automated tests that cover both functional and non-functional aspects of the service.
- Releases are made more quickly because performing API testing typically saves software development teams up to eight hours compared to performing UI testing.
