I have opened a bug with Jetbrains but I am hoping that posting in SO will get more visibility.
Instead of running the test from the bin\debug directory, the directory is being changed to: C:\Users\{username}\AppData\Local\JetBrains\Installations\ReSharperPlatformVs12
JetBrains ReSharper Ultimate 10.0.2 Build 104.0.20151218.120627 ReSharper 10.0.20151218.130009
The current workaround I have is:
- uninstalling ReSharper version 10
- uninstall NUnit 3
- Install ReSharper version 9.2
- installing NUnit Version 2.6.4.
Here is the bug: https://youtrack.jetbrains.com/issue/RSRP-453391
