Cloud Function source is in Cloud Source Repositories. Only one service account can deploy. Ensure code cannot be deployed unless unit tests pass. How should you configure the testing and deployment process?

The correct answer leverages Cloud Build for automated testing and deployment, which is a standard CI/CD practice. Cloud Build can execute unit tests, and if they pass, proceed with deploying the Cloud Function. Using a specific service account as the build agent ensures that only authorized deployments occur, addressing the requirement for a single service account to deploy. The first incorrect option introduces a manual approval step, which isn't necessary if the goal is automated deployment upon successful tests. The second incorrect option suggests running unit tests after deployment, which defeats the purpose of preventing bad code from reaching production. The third incorrect option requires manual deployment by the developer, which contradicts the automation goal and doesn't utilize the specific service account for deployment directly through the pipeline.
