Solution to "Could not find a part of the path 'C:\Users\\AppData\Local\Temp\TestResults\Out\'." when running Unit Tests via ReSharper in Visual Studio 2012

Took me a bit to find the solution to this one, but I eventually found it here.

1. Upgrade to Resharper 7.1.2

2. In VS go to Resharper –> Options –> Unit Testing –> MS Test and Uncheck “Use Legacy Runner”
