   A developer is using an AI coding assistant to generate unit tests for a Python function that calculates shipping costs based on weight, destination zone, and a customer loyalty discount. The AI assistant produces a test that only checks the happy path with a standard weight and no discount. The developer wants to improve the test suite's effectiveness before committing. What should the developer do?

   • APrompt the AI assistant to generate additional tests for boundary weights, each zone, and discount thresholds, then review them for correctness.
   • BAccept the generated test as-is and rely on integration tests to cover edge cases.
   • CDelete the generated test and write all tests manually to ensure quality.
   • DRun the generated test against the code and if it passes, consider the function adequately tested.

   A team's Cloud Build pipeline runs integration tests that need to access a Cloud Storage bucket in a different project. The build runs with a service account that has the Storage Object Viewer role on the bucket. The tests are failing with a 403 error. The team wants to fix the issue with the least privilege. What should they do?

   • AMake the bucket public so the tests can access it without authentication.
   • BGrant the service account the Storage Object Admin role on the bucket.
   • CUse the default Cloud Build service account instead of a custom one.
   • DVerify that the service account is correctly specified in the cloudbuild.yaml step and that the bucket permissions are granted to that exact service account.
