Why is it not possible to inherit tests methods from other assemblies

Question

WHy is it not possible to inheritance tests from other assemblies to run:

namespace TestProject.Base
{
    [TestClass]   
    public abstract class TestBaseClass
    {
        [TestMethod]
        public void BaseTest()
        {
            Assert.IsTrue(false);
        }
    }
}

Test Runner

namespace TestProject.UnitTest
{   
    [TestClass]
    public class UnitTest : TestBaseClass
    {
    }
}

It is ONLY possible to do run the test when the classes are in the SAME assembly WTF!

Is it possible to have test inheritance like above with NUnit and be runnable?

Answer 1

You must reference the assembly containing the class you wish to inherit from.

This has nothing to do with the fact that you're trying to run a test. It's because of the way code is linked.
