NUnit TestCase with Generics

Question

Is there any way to pass generic types using a TestCase to a test in NUnit?

This is what I would like to do but the syntax is not correct...

Answer 1

I had occasion to do something similar today, and wasn't happy with using reflection.

I decided to leverage [TestCaseSource] instead by delegating the test logic as a test context to a generic testing class, pinned on a non-generic interface, and called the interface from individual tests (my real tests have many more methods in the interface, and use AutoFixture to set up the context):

class Sut
{
    public string ReverseName()
    {
        return new string(typeof(T).Name.Reverse().ToArray());
    }
}

[TestFixture]
class TestingGenerics
{
    public IEnumerable TestCases()
    {
        yield return new Tester { Expectation = "gnirtS"};
        yield return new Tester { Expectation = "23tnI" };
        yield return new Tester> { Expectation = "1`tsiL" };
    }

    [TestCaseSource("TestCases")]
    public void TestReverse(ITester tester)
    {
        tester.TestReverse();
    }

    public interface ITester
    {
        void TestReverse();
    }

    public class Tester : ITester
    {
        private Sut _sut;

        public string Expectation { get; set; }

        public Tester()
        {
            _sut=new Sut();
        }

        public void TestReverse()
        {
            Assert.AreEqual(Expectation,_sut.ReverseName());
        }

    }
}
