Why does Resharper not pick up my NUnit tests?

Question

I recently converted from MSTest to NUnit. I did this by

• replacing all occurrences of [TestMethod] by [Test], [TestClass] by [Test], etc.
• I also deleted the Microsoft.VisualStudio... reference and added the NUnit.framework nuget package.

Since I've done that, Resharper isn't showing the little testing icon next to the methods. And if I run the tests using Ctrl + U, R it shows the right count but doesn't actually run any of them.

Does anyone have any idea?

Edit: There must be something screwed up with my assembly because I created a new one just called Test.Web and created a simple class with just the [TestFixture] and Resharper recognized it instantly.

Answer 1

I had the same problem and i solved it like this:

1. Go to Resharper Options -> Tools -> Unit Testing -> Unit testing providers
2. Unselect anything but Nunit and press OK.
3. It should work now and you can even reselect the providers that you disabled and it should still work.

Answer 2

Removing the .ReSharper.user file from the source directory (in the same directory as the solution file) solved the same problem for me.
