#instance_spy(doubled_class) ⇒ Object #instance_spy(doubled_class, name) ⇒ Object #instance_spy(doubled_class, stubs) ⇒ Object #instance_spy(doubled_class, name, stubs) ⇒ Object

Constructs a test double that is optimized for use with have_received against a specific class. If the given class name has been loaded, only instance methods defined on the class are allowed to be stubbed. With a normal double one has to stub methods in order to be able to spy them. An instance_spy automatically spies on all instance methods to which the class responds.
