Skills measured
Understanding of API technologies
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
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
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.
Knowledge of programming languages
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
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
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.
