Worked on modernizing the development container and enhancing webhook testing for the kyverno/kyverno repository. Focused on backend development using Go and Kubernetes, the work included upgrading the development container’s Go version from 1.24 to 1.25 to ensure compatibility with the latest language features. Expanded testing coverage for admission webhook handling by introducing comprehensive filter webhook handler tests and unit tests for admission handler logic, all structured in Go and JSON. These improvements aimed to increase reliability, reduce regression risk, and streamline developer workflows by maintaining code quality and enabling smoother integration cycles through better test coverage and up-to-date tooling.
