CSE 231 Problem Set 06 Each problem in the problem set will start with the following two classes: Problem 34.1: Dummy Create a dummy double for the Velocity class. Problem 34.2: Stub Create two stubs for the Velocity class: One that returns DX,DY of 1.1,2.2, and a second that returns a DX,DY of 11.1, 22.2. Problem 34.4: Spy Create a spy double for the Velocity class. This double will count the number of times that Velocity::getDx () or Velocity: :getDy () are called. Note that this spy double will be a stub that always returns DX,DY=1.1,2.2. Problem 34.5: Spy Utilization Add the following unit test to the TestPosition class: Note that you will also have to call this method from run(). Please modify the above method to include your spy form 34.4. Note that you should add an assert to ensure the expected number of calls to getDx( ) and getDy( ) were performed
