One of the hot-keys I used most in Visual Studio 2010 was Ctrl+R, Ctrl+T, which ran the unit test the cursor currently was on in debug mode. I think the command is named "Debug tests in current context". Now, you still have a command named
Test.DebugTestsInCurrentcontext, but when I assign it to a key combination and activate it, it always yields "currently not available".
I do know that there is a new function in the Test menu named "Debug selected test" - but I think that mappes to the selected tests in the Test Explorer, not the file editor.
What gives, Microsoft? Are you removing features?
