Lightning Talk: Unit Testing in Go With K8s Clients & APIs: An Intern’s POV on Why I...
summary
Unit testing with Kubernetes fake clients cuts cluster setup time to zero and makes debugging the fastest way to learn a Go + K8s codebase, using informers and controllers to exercise API-driven behavior in isolation. Tests run locally and in CI (GitHub Actions or Jenkins) for fast, reliable feedback. Limitations include RBAC and ephemeral networking only reproducible in real clusters. A working CLI for custom resources demonstrates the approach scales from tests to real tooling.
