Today I was writing some tests (as I do every day), and I wrote this.

[Test]
public void IfLanguageChangesToNlWhenbtnDutchIsClicked()
{
  var _mocks = new StructureMap.AutoMocking.RhinoAutoMocker<FrmMenu>();
  var _menu = _mocks.ClassUnderTest;
  var language = _mocks.Get<ILanguageSettings>();
  language.Expect(x => x.Language)
    .Return(Enumerations.Languageoptions.nl);
  _menu.btnDutch.RaiseClick();
  Assert.AreEqual(Enumerations.Languageoptions.nl,language.Language);
}```
I used [Rhino mocks][1] for this.

FrmMenu has these three buttons.

```vbnet
''' <summary>
        Private Sub btnDutch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDutch.Click
            Me.Language.Language = Enumerations.Languageoptions.nl
        End Sub

So the test should check if the language changes to dutch when I clikc that button.

But I’m not testing my code I’m testing [Rhino mocks][1]. And that can never be the point. Because that test will always pass (unless [Ayende][2] did something really stupid)

I rewrote the test like this.

[Test]
public void IfLanguageChangesToNlWhenbtnDutchIsClicked()
{
  var _mocks = new StructureMap.AutoMocking.RhinoAutoMocker<FrmMenu>();
  var _menu = _mocks.ClassUnderTest;
  var language = _mocks.Get<ILanguageSettings>();
  _menu.btnDutch.RaiseClick();
  language.AssertWasCalled(x => x.Language = Enumerations.Languageoptions.nl);
}```
And now I’m testing the right thing.
