Testing Microservice A
Question
You have two microservices, A and B running in production.
Service A relies on APIs from service B.
You want to test changes to service A without deploying all of its dependencies, which includes service B.
Which approach should you take to test service A? (Choose the best answer.)

A. B. C. D.B.
https://docs.oracle.com/cloud/apiary/tools/mock-server/index.htmlThe best approach to test service A without deploying all of its dependencies, including service B, is to test using API mocks.
API mocks are dummy implementations of the APIs that mimic the behavior of the actual APIs. By using API mocks, you can simulate the behavior of service B and test service A's interactions with it without having to deploy the entire service B.
Testing against production APIs (option A) is not recommended because it could potentially disrupt the production environment and affect other services that rely on service B.
Option C, stating that there is no need to explicitly test APIs, is incorrect because APIs are an essential component of microservices architecture, and testing their functionality is crucial to ensuring that the services are functioning as intended.
Testing the APIs in private environments (option D) can be a good approach, but it may require deploying a separate environment, which could be costly and time-consuming. Moreover, it may not accurately simulate the behavior of service B in the production environment.
Therefore, the best approach is to use API mocks to test service A's interactions with service B's APIs in isolation. This approach is faster, less expensive, and less disruptive to the production environment, while still providing valuable insights into service A's functionality.
