Which of these “properties” of testing using stubs and drivers are correct?
a) Using drivers and stubs is a lot of work for not much gain. b) Using drivers and stubs avoids trying to debug a large program all at once. c) Testing the pieces is difficult to do in any significant way. You need the entire program to run a meaningful test. d) Drivers run the pieces individually. They are temporary.
