Worked on the kyverno/kyverno repository to enhance the testing infrastructure by introducing a new fake client creation method in Go, specifically NewFakeClientWithDisco, which streamlined policy validation workflows and reduced error noise in continuous integration environments. The approach involved exposing an isFake parameter throughout policy application helpers, allowing for more flexible and test-friendly policy management. By aligning fake client usage with existing cluster simulation patterns in Kubernetes, the changes improved test reliability and developer productivity. The work focused on backend development, emphasizing testability and faster feedback loops, ultimately enabling more robust and maintainable policy validation for developers and operators.
