Mountkirk Games wants you to design their new testing strategy. How should the test coverage differ from their existing backends on the other platforms?

Mountkirk Games is migrating to Google Cloud, implying a need for a scalable and robust testing strategy. Cloud environments offer significant scalability, and the testing approach should leverage this by being able to scale beyond traditional on-premise or less dynamic platforms. This ensures the testing can keep pace with the potential growth and elasticity of cloud resources. Unit tests remain crucial for code quality and are complementary to end-to-end tests, not replaced by them. Testing after production release is reactive and costly, contradicting good development practices. While infrastructure as code (IaC) can be tested, directly testing GCP's underlying infrastructure is Google's responsibility, not the user's; users test their applications and configurations on GCP.
