Unit testing the Viewmodel

Question

I am sort of new to TDD. I have started creating the properties I need on the view model as plain auto property.

public string Firstname { get; set; }

You can do something like this:

    [TestMethod]
    [Tag("Property")]
    public void FirstNameTest()
    {
        bool didFire = false;
        ViewModel = new CustomerViewModel();
        ViewModel.PropertyChanged += (s, e) =>
                                         {
                                             didFire = true;
                                             Assert.AreEqual("Firstname", e.PropertyName);
                                             Assert.AreEqual("Test", ViewModel.Firstname);
                                         };
        ViewModel.Firstname = "Test";
        Assert.IsTrue(didFire);
    }
