What is a REST API test?
The REST API test evaluates a candidate's knowledge and skills related to testing and validating RESTful web services. This test aims to assess the candidate's understanding of REST principles, proficiency in working with HTTP methods, knowledge of common API testing frameworks and tools and ability to ensure the functionality and reliability of REST APIs.
The REST API test includes multiple-choice questions which require candidates to demonstrate their ability to construct and send HTTP requests, validate and verify responses, handle authentication and authorization mechanisms, test different endpoints and query parameters and handle error conditions effectively.
The increasing prevalence of RESTful web services and the importance of APIs in modern application development have made REST API testing more commonly used. Organizations seek candidates who can thoroughly test APIs to ensure they work as intended, integrate well with other systems and handle various scenarios and data formats securely and accurately.
To excel in a REST API test, candidates need to showcase their understanding of REST principles, exhibit proficiency in working with HTTP protocols and methods, demonstrate knowledge of common API testing frameworks (e.g., Postman, RestAssured) and concepts like test data management, request/response validation and test automation.
Candidates should also be familiar with common API authentication mechanisms such as OAuth and JWT. Additionally, candidates should demonstrate their ability to analyze API documentation, design comprehensive test cases and effectively handle edge cases and error scenarios in API testing.
