Code coverage for async methods

Question

When I analyse code coverage in Visual Studio 2012, any of the await lines in async methods are showing as not covered even though they are obviously executing since my test

Answer 1

This can happen most commonly if the operation you're awaiting is completed before it's awaited.

I recommend you test at least synchronous and asynchronous success situations, but it's also a good idea to test synchronous and asynchronous errors and cancellations.
