Today's Lab Work

Work on Assignment 2. At a minimum, you should be able to complete part 1 (Exercise 7.14) and part 2 (Exercise 7.18), and make a reasonable amount of progress on part 3 (Exercises 7.20 and 7.22).

Where feasible, develop JUnit test classes to your code. For example, in Exercise 7.18 you will be writing two methods that return String objects. Writing tests for these methods is simple. (In fact, because these methods are so simple, do we really need to write tests for them? What are the pros and cons of doing this?) Much of the code you'll write for Exercises 7.20 and 7.22 is a good candidate for automated unit testing. On the other hand, perhaps Exercise 7.14 is best tested interactively, because a Game object obtains input from a player (by using the Parser object), and the look() method outputs results to the console. This suggests that determining if this part of program is correct is best handled by having a player invoke the command and observe the resulting behaviour.
