Your Spring Boot application has complex business logic that involves interactions between various beans. How would you approach testing such business logic, ensuring that the interactions between beans are correct and that the business logic produces the expected outcomes?

To ensure the correctness of interactions between beans and the expected outcomes of complex business logic, you should use unit tests to verify the behavior of individual beans and integration tests to verify interactions between beans. This approach allows you to isolate and test individual components as well as their interactions. Skipping interactions or testing only the final outcome is not sufficient for comprehensive testing. Manual testing for bean interactions is not a scalable or reliable approach for complex applications.
