How do you handle versioning in REST APIs using REST Assured?

• A. By setting a version variable in the test environment
• B. By including version numbers in the API URL or headers
• C. By using a configuration file to manage versions
• D. By appending versioning in the JSON payload

Answer: (B)

Handling versioning in REST APIs is a vital aspect of API design, and option B captures the most widely adopted method. Including version numbers in the API URL or headers is a practical approach that allows consumers of the API to explicitly specify which version they want to interact with. This means that you can maintain multiple versions of an API simultaneously without breaking existing client applications. For example, versioning in the URL could look like `/api/v1/resource` or `/api/v2/resource`, allowing clients to request a specific version directly. This method is straightforward, enhancing clarity and ease of usage, as each version can evolve independently without impacting other versions. In contrast, other methods may not be as effective or standardized. Setting a version variable in the test environment may help during testing but does not provide a clear way for clients to specify API versions. Using a configuration file to manage versions can work internally, but it does not align with standard practices of API versioning and might complicate deployment. Lastly, appending versioning in the JSON payload does not provide the same level of clarity and flexibility, as it may require changes to the payload itself, which could lead to issues in backward compatibility and make it more difficult for clients to interact with the API.
