# Unit testing relies on using doubles to test the object in isolation

"why do we need a double when we have the RN class now (in a separate file)?" -> You want to test each class isolated from all other classes. (This also goes with our conversation about class encapsulation) So you use doubles to stand in for other objects that the class that you are testing 'needs'.
