Visual Studio 2012 not recognize unit tests

I'm struggling with this issue several days. Visual Studio can't recognize tests in file so I cannot run or debug it. My colleges have own copy and works correctly.

I have tried:

1. Cleared \AppData\Roaming\JetBrains


2. Cleared cache inside Resharper, rebuild, deleted .suo file


3. Removed all addons: Code maid, Hide main menu, Productivity Power Tools 2012, VS Commands. VsVim and Ankh are installed.


4. Unchecked Resharper>Options>Unit Testing>Shadow-copy...., cleaned, rebuild.


5. Run VisualStudio as Administrator.


6. Test classes and methods are public.


7. Tried change TEST -> Test Settings -> Default Processor Architecture from x86 to x64.


8. Windows Update run and installed all updates VS Pro 2012 Version 11.0.61030.00 Update 4


9. Installed lastest resharper version v7.....

Google is no longer for me, the results of which I had not seen, so guys do you have some tips?
