VS2010 doesn't “see” any of the tests in a new test class

Question

I've created a class of Unit tests in an existing project (as opposed to creating a whole new test project)

When trying to run the tests via the Test menu VS claims that no tests are loaded..

How do I solve this ? (except for rewriting all the unit tests in Nunit, that is )

Editing to answer the questions: the class and methods are public, [TestClass] and [TestMethod] annotations are all there

[TestClass]
    public class FunctionalTests
    {        

        [ClassInitialize()]
        public void ClassInit()
        {
            //do init stuff
        }


        [TestMethod]
        public void TestSomething()
        {
           //testing stuff
        }

Answer 1

Check that the class has the [TestClass] attribute and that the tests methods has the [TestMethod] attribute. It happened to me once and this was the problem.

Answer 2

我放弃了尝试使用VS2010的尝试，而是为测试创建了一个新的单独项目，一切都很好。

Answer 3

The ClassInitialize and ClassCleanup methods need to be static .

    [ClassInitialize()]
    public static void ClassInit()
    {
    }

    [ClassCleanup]
    public static void ClassCleanup()
    {
    }
