   A team has a microservice that calls an external payment API and then updates its own database. They want to write an integration test to verify the interaction between the service and the API. Using Copilot, what is the most appropriate approach for the initial test scaffold?

   • ATest only the database update logic in isolation without involving the API call
   • BUse a test double for the payment API and assert that the service sends the correct request payload and handles the response
   • CMock the database and verify the API is called with the correct parameters
   • DCall the real payment API with a small test amount and assert the database is updated
