You have an application running in a production Google Kubernetes Engine (GKE) cluster, with Cloud Deploy handling automated deployments to production. As part of your development workflow, you plan to make frequent changes to the application's source code and need to choose tools for testing these changes locally before pushing them to the remote repository. Your selected tools must:

• Automatically test frequent local changes.
• Emulate the production deployment environment locally.

Which tools should you use to test building and running a container on your laptop with minimal resource consumption?
