Typemock
The Training Management application includes unit testing with mock objects. There are a variety of tools available that support this approach. The Training Management application uses a commercially available tool named Typemock Isolator. This is a valuable tool because you can use it to create mock instances of classes that have internal constructors. You can also use it to specify the behavior of class methods even though the class is sealed.
