Nunit Test Runner shows "Inconclusive: Test not run"

using NUnit.Framework;

namespace MyProject.Tests
{
    [TestFixture]
    public class TestValidation
    {
        [Test]
        public void ValidationTestGood()
        {
            string basepath = "C:\\APAATJCD";
            DatasetValidator validator = new DatasetValidator(basepath);
            validator.ValidateTxt();
            Assert.AreEqual(ValidationStatus.VALID, validator.Status);
        }
    }
}

Right clicking the method definition and running the test(s) gives the above result in the Resharper test runner. I have tried clearing Resharper Cache, reinstalling resharper, redownloading nunit package... What can I do to allow the test to run again?

.net: 4.5
Nunit: 3.0.1
Resharper: 10.0.1 Ultimate
