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.

Assessing a candidate's understanding of API technologies is crucial to determine their expertise in creating and testing APIs. The subskill includes knowledge of API architectures, types of APIs, RESTful API principles, API documentation, API testing tools, and the API lifecycle.
Test case creation is an essential subskill in API testing as it enables candidates to develop effective test cases, which ensure the quality and reliability of APIs. It includes defining test objectives, selecting appropriate test data, creating test cases, and reviewing and validating test cases.
Test execution and reporting involve executing test cases and documenting the results to provide feedback to the development team. This subskill assesses a candidate's ability to execute test cases, log defects, and report test results accurately.
Assessing a candidate's knowledge of programming languages such as Java, Python, C#, or Ruby is crucial to determine their ability to write code for test automation and to create complex test cases.
API security testing is a critical subskill in API testing as it ensures the security of sensitive information shared through APIs. The subskill includes knowledge of security testing tools, OWASP top 10 security risks, and security testing methodologies.
Performance testing is an essential subskill in API testing as it ensures that APIs meet performance requirements such as response time, throughput, and concurrency. The subskill includes knowledge of performance testing tools, performance testing methodologies, and load testing.
