Tests showing twice in Unit Tests pad - Visual Studio 2017 for Mac

In a new project for which I'm creating UITests, my Tests (iOS) and Tests (Android) are showing twice.

If it was just a display artefact I could live with it, however when I run a test, it runs twice!

I've tried:

  • Cleaning the solution
  • Obliterating output paths
  • Editing the UITest project file to see if there are any duplicate references etc.
  • Deleting the Visual Studio cache folder

This problem is only occurring on this new project. Previous projects are fine.

Thoughts?

Solution

  • The problem was caused by my Tests class inheriting from a BaseTestFixture class and both of them having the

    [TestFixture(Platform.Android)]
[TestFixture(Platform.iOS)]

    attributes.

    Removing these attributes from my derived class solved the problem.
