Microservice Testing Techniques
summary
Explains concrete testing choices: use mocks for fast unit feedback, use TestContainers to spin real databases inside tests, and use Hoverfly service virtualization to record/replay and inject network failures for legacy systems. Claims a practical tipping point of about 10 services where running everything locally breaks. Demonstrates Telepresence intercepting Kubernetes traffic so a remote cluster routes a service to a local debugger, the demo works and lets one debug, profile, and swap a single service while the rest stays remote.
