Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type SmartAssertPlaceHolder. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).
BadTestException If exceptions are not public properties of the instance involve in the Act.
SmartTestException If any public property, of the instance involved in the Act, except the exceptions have changed.
This Assertion ensures that:
  1. Before the Act -

    If names in exceptions are not public properties of the instance involved in the Act, a BadTestException is thrown.

  2. After the Act -

    If a public property changed during the Act (except exceptions), a SmartTestException is thrown.

In this example, the Smart Assertion verifies that no public property of mc, except MyProperty and OtherProperty changed while calling MyMethod.
public void CopyFromTest()
    var mc = new MyClass();
    RunTest( ValidValue.IsValid,
             () => mc.MyMethod(),
             SmartAssert.NotChangedExcept() );
