title: Is there any way to mock Azure CloudQueueClient or CloudQueue?
body: <p>I am writing unit tests for my code and have come across a method, which throws a StorageException when trying to Create a queue and AddMessage to the queue. I would like to test if the exception handling works fine. In order to do that I had an idea of using a mock for the CloudQueue, but later found out this class is sealed. Is there any way to test the exception handling (or force a StorageException) without actually changing the production code?</p>
