]]> 828 Benefits of API Test Automation over UI Test Automation? – Mostly asked Interview Question https://fullstackqe.org/benefits-of-api-test-automation-over-ui-test-automation-mostly-asked-interview-question/ Sat, 12 Nov 2022 19:52:48 +0000 https://fullstackqe.org/?p=815 API testing has many benefits over UI testing:

  • First, API testing is much faster than UI testing. This is because API tests do not have to wait for a page to load, as they interact directly with the application’s backend.
  • Second, API tests are more reliable than UI tests. This is because UI tests are subject to the vagaries of the user interface, such as changes in the layout or position of elements. API tests, on the other hand, are not affected by such changes.
  • Third, API tests are easier to create and maintain than UI tests. This is because UI tests often require a lot of code to simulate user interactions, whereas API tests only need to make calls to the application’s API.
  • Fourth, with API testing, one can find bugs related to functionality, reliability, performance, and security early in the SDLC and hence those are cheaper to fix.

In conclusion, API testing has many advantages over UI testing, and should be used whenever possible.

]]> Seems easy but yet a tricky interview question. Here is the answer by Katalon experts:

During the API testing process, a request is raised to the API with the known data. This way you can analyze the validation response. While testing an API, you should consider:

  1. Accuracy of data
  2. Schema validation
  3. HTTP status codes
  4. Data type, validations, order and completeness
  5. Authorization checks
  6. Implementation of response timeout
  7. Error codes in case API returns, and
  8. Non-functional testing like performance and security testing
