Your team observed a surge of errors in a Cloud Run application within your production environment. The application is set up to consume messages from Pub/Sub Topic A, process them, and publish the results to Topic B. To diagnose the root cause of the errors, you plan to use a collection of mock messages for testing. What steps should you take?
A
Deploy the Pub/Sub and Cloud Run emulators on your local machine. Deploy the application locally, and change the logging level in the application to DEBUG or INFO. Write mock messages to topic A, and then analyze the logs.
B
Use the gcloud CLI to write mock messages to topic A. Change the logging level in the application to DEBUG or INFO, and then analyze the logs.
C
Deploy the Pub/Sub emulator on your local machine. Point the production application to your local Pub/Sub topics. Write mock messages to topic A, and then analyze the logs.
D
Use the Google Cloud console to write mock messages to topic A. Change the logging level in the application to DEBUG or INFO, and then analyze the logs.
