"TestDriven.NET" has a great feature called "test with debugger". Is there anything like this in ReSharper?
Tried googling this, but can't find anything.
ReSharper does not have this exact feature. You have to stick with TestDriven.NET for this feature. Or better add full-blown tests to your project, and then you'll be able to run them in debugger (via ReSharper).
