I have a somewhat major issue here and I have no idea how to debug the problem. First off I am running VS2012 Update 2 (v11.0.60315.01). Unit Tests had been running and I noticed today that they quit working. I was working on something different past week or so so it's been at least a week or 2 since I last ran any unit tests.
All of the tests are stuck in the Pending state in the Unit Test Session window. I even tried spinning up a new test harness and running some simple unit tests. They behave identically, so I don't think this is a single solution issue.
I have obviously rebooted the machine which included restarting VS.NET 2012 as well. I'm not getting any errors, messages, problems, etc. The unit tests are all just stuck in the Pending state and none of them will run.
I ran the .dll that comprises my tests using the vstest.console.exe tool and I get the result "Test Run Successful", "Test execution time: 0.4952 seconds". OK, this tells me I have a problem with VS2012 because the tests run independently using the command line.
How can I debug this issue? I see solutions for deleting settings files for individual solutions but this seems like an issue across the board with VS2012. Any suggestion on how to fix this?
