How do you approach testing and debugging in a microservices architecture during software development?

I'm currently working on a software development project where we're implementing a microservices architecture. While this approach offers flexibility and scalability, we're encountering challenges in testing and debugging our services effectively. I'm particularly interested in strategies for unit testing, integration testing, and end-to-end testing in a microservices environment. How do you ensure that services communicate correctly and handle failures gracefully? Additionally, if anyone has experience with tools or frameworks that can streamline debugging across multiple services, I'd love to hear your recommendations. Any insights on managing dependencies, data consistency, or testing automation would also be greatly appreciated.
