ReSharper not running new unit tests
It also helped me to make the unit test class public :D
Unit test methods must be public.
This test will not be recognized:
[Test]
void RunTest(){
Assert.True;
}
Whereas this test is recognized:
[Test]
public void RunTest(){
Assert.True;
}
Try cleaning the solution and delete RS related files and folders from your project folder. It has worked for me. I use VS2008 though.
