You are tasked with ensuring that all components of a microservice are working well together in a Spring Boot application. What testing strategies and tools would you employ to ensure the correctness of interactions among components?

In this scenario, you would use unit testing with mocked dependencies to isolate and test individual components of the microservice. This helps ensure that each component functions correctly in isolation. Integration testing with real external services can introduce complexity and is not suitable for ensuring the correctness of interactions among components. Manual testing and ignoring component interactions are not effective strategies.
