BadTestException If the involved instance in the Act is not an INotifyPropertyChanged instance.

If the INotifyPropertyChanged event is raised for any property.

This Assertion ensures that:
  1. Before the Act -

    Nothing special.

  2. During the Act -

    Ensures the PropertyChanged event is not raised for any property.

  3. After the Act -

    If the event is raised, a SmartTestException is thrown.

In this example, the Smart Assertion verifies that the PropertyChanged event is not raised for any property of mc.
public void MyMethodTest()
    var mc = new MyClass();
    RunTest( ValidValue.IsValid,
             () => mc.MyMethod(),
             SmartAssert.NotRaised_PropertyChanged() );
