Worked on enhancing the end-to-end testing framework for the confidential-containers/cloud-api-adaptor repository, focusing on multi-container scenarios. Leveraged Go and Kubernetes to refactor the PersistentVolumeClaim (PVC) and Secret binding logic, enabling support for multi-container deployments within the test suite. Introduced configurable options for PVC creation and implemented a post-creation delay to ensure reliable resource binding, which addressed test flakiness and improved integration validation. These changes increased the flexibility and robustness of the testing framework, resulting in broader test coverage and more realistic simulation of production environments. The work emphasized maintainability and reliability in automated test workflows.
