Mocking a third-party SDK

Tests mock the AWS SDK's S3 client methods directly in 40 places. An SDK upgrade changes return shapes, all tests stay green, and production breaks. What is the better design?

A.Mock the SDK in even more detail so that the mocks match every possible responseB.Wrap the SDK in your own small adapter, mock that, and test the adapter against the real serviceC.Pin the SDK version forever so that its responses can never changeD.Remove all tests that touch storage and rely on manual checks
