How to Use Rhino Mocks/Mocks, Dynamic Mocks, Partial Mocks

The difference between these three types of Rhino Mocks mocking solutions has always been a little confusing to me. So, here's my best shot at some concise definitions:


 * A normal mock object will throw an exception when a method, which has no explicit expectation defined, is called on the mock instance.
 * A dynamic mock, instead of throwing an exception, will return null or 0 for any unexpected method calls.
 * A partial mock, like a dynamic mock, will not throw an exception if a method is called when there is no expectation defined for the method; but, instead of returning 0 or null, a partial mock will call the actual implementation method (i.e., not the mock) on the object and return that value. This lets you selectively mock specific methods on an object.
