Explore microservices testing techniques using mock-server in this 29-minute Devoxx conference talk. Learn how to isolate and test microservices by mocking dependencies, treating them like unit tests. Discover how to implement mock-server with familiar tools such as JUnit, Maven, and Docker. Gain insights into running mock-server locally, integrating it into Maven builds, and deploying it as a Docker image in cloud environments. Follow along as the speaker demonstrates practical applications, including setting up tests, using test containers, creating services, initializing clients, and performing verifications and inspections. Understand the advantages of mock-server over Kubernetes for certain testing scenarios and see a real-world example using an overengineered Mastermind game. By the end of this talk, acquire valuable skills to enhance your microservices testing approach and improve overall development efficiency.
