Best practices for testing and debugging microservices

Testing and debugging microservices effectively can be challenging due to the distributed nature of its architecture. However, following certain best practices can streamline the process, make your services more reliable, and help you catch potential issues before they impact production. In this section, we’ll focus on practical strategies using the sample code and concepts we’ve explored earlier.

Isolating microservices for unit testing

While integration testing across services is essential, unit testing each microservice independently ensures that individual services behave as expected. In microservice testing, isolation is crucial because each service should be tested without dependencies on other services.

You can achieve this by mocking or stubbing dependencies, such as database calls, external APIs, or other services. Here’s an example of how to mock a dependency when unit testing OrderService...
