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; }
         


        

Answer 1

Perhaps there is more background to this code that is not being revealed, but what I am seeing seems unnecessarily complicated. Why bother hooking into the RaisePropertyChanged event at all? Just check the property after setting it.

[TestMethod]
[Tag("Property")]
public void FirstNameTest()
{
    var expected = "John";
    var sut = new CustomerViewModel();

    sut.Firstname = expected;

    Assert.AreEqual(expected, sut.Firstname);
}

This also turns the test into a true unit test.
