Another Way to Test Your Microservices
summary
The talk tackles testing microservices where dependencies and external services (databases, cache, queues) make unit tests invasive and incomplete. It presents a “grey-box” testing strategy used at OVHcloud, explaining concepts, pros and cons, and shows practical implementation using Shell and Docker, the Venom declarative test runner, and the Smocker HTTP mock server to test a single service in isolation and then interconnected microservices.
