API Testing 面试题与答案
问题 21. How do you handle API versioning to ensure backward compatibility?
API versioning is often done using URL versioning, custom headers, or request parameters. Testers need to ensure that changes in versions do not break existing functionality.
问题 22. What is the purpose of the 'OPTIONS' HTTP method?
The 'OPTIONS' method is used to describe the communication options for the target resource. It is often used to support cross-origin resource sharing (CORS).
问题 23. Explain the term 'Load Testing' in the context of API testing.
Load testing involves assessing the performance of an API by subjecting it to a specific load, often by simulating multiple concurrent users or requests. It helps identify performance bottlenecks.
问题 24. What is the purpose of the 'ETag' header in an HTTP response?
The 'ETag' header provides a mechanism for caching and conditional requests. It represents a unique identifier for a specific version of a resource.
问题 25. How do you handle testing for paginated APIs?
Testing paginated APIs involves verifying that the pagination parameters work correctly, ensuring that the correct number of items is returned per page, and testing the behavior of pagination links.
