Use of API Testing test

API testing is the process of evaluating the functionality, performance, security, and reliability of an API (Application Programming Interface).

API Testing is crucial in software development as it ensures the quality of APIs that make up the applications. This assessment evaluates the candidate’s understanding of API testing and its practical application, including different testing techniques and tools used in the process.

API Testing assesses the candidate’s ability to identify and resolve issues while interacting with APIs and testing the application’s functionality, security, and performance. The test covers essential sub-skills like API endpoint testing, RESTful API testing, error handling, security testing, and load testing.

Assessing a candidate’s API testing skills is crucial while hiring as it ensures the quality of the application, prevents potential risks and helps organizations maintain a good reputation. A candidate with a strong API testing skill set can identify issues early in the development process, leading to cost reduction and timely delivery. They can also effectively communicate the issues to developers and provide them with valuable insights into improving the application’s performance and security.
