Google Cloud:

Foxx's current technology stack cannot provide the scale needed, so they want to replace MySQL and move to an environment that provides autoscaling, low latency load balancing, and frees us up from managing physical servers. They historically used cloud providers to lease physical servers. They plan to deploy the backend on Google Compute Engine so they can capture streaming metrics, run intensive analytics and take advantage of its autoscaling server environment and integrate with a managed NoSQL database.  Foxx wants you to design their new testing strategy. How should the test coverage differ from their existing backends on the other platforms?

A. Tests should scale well beyond the prior approaches.

B. Unit tests are no longer required, only end-to-end tests.

C. Tests should be applied after the release is in the production environment.

D. Tests should include directly testing the Google Cloud Platform (GCP) infrastructure.
