The following table displays 11 graphs and their construction:

Task 1: Each of these graphs contains regions, some counting as complete, some as incomplete. Turn each of these cases into a test case for complete-region. You will naturally use insert-tile to construct these graphs, so you will test this function implicitly. [POINTS: 6]

Task 2: Next turn each of the completed regions of these graphs into a test case for score. [POINTS: 6]

Task 3: Finally, use the graphs to test potential-locations-for-tile. [POINTS: 6]

In order to test the functions that find followers in a completed region and find places where players can place followers, I have found it convenient to develop a function that adds followers to graphs, regardless of whether it is legal or not to place them there at the moment:

   (define graph-tile<%>
    (interface (tile<%>) ;; the interface for the graph 
      ...  
      place-follower ;; Position Follower -> Void
      ;; effect: occupy the specified position on _this_ tile with the follower
      ;; ASSUME: the tile position is available 
      ... 
      ))

Using this function/method, you can modify the above graphs as follows:

image of graph	construction of graph
	place RED follower at (0,1) INNER
	place RED follower at (0,1) INNER
	place BLUE follower at (0,-1) INNER
	place RED follower at (0,0) NORTH
	place BLUE follower at (0,-1) INNER place BLUE follower at (0,-2) SOUTH
	place RED follower at (0,0) NORTH place RED follower at (1,0) NORTH place blue follower at (0,-1) INNER
	place RED follower at (0,0) NORTH place RED follower at (2,-1) INNER
	place BLUE follower at (-1,0) EAST
	place BLUE follower at (-1,0) EAST place RED follower at (1,0) EAST
	place BLUE follower at (-1,0) EAST place RED follower at (1,0) EAST place RED follower at (2,0) WEST
	place BLUE follower at (0,0) EAST
	place BLUE follower at (0,0) EAST place BLUE follower at (2,0) EAST place RED follower at (2,0) WEST place BLACK follower at (2,0) SOUTH
	place BLUE follower at (0,+1) EAST

Task 4: Use the first set of graphs and the above to test the function that finds all the followers on the given region. That is, first extract the recently completed regions, then find all the followers on these regions. [POINTS: 6]

For potential-locations-for-followers, you can reuse the above, making sure that your methods don't reuse positions. Also, use generate the graphs below for additional scenarios:

	place RED follower at (0,0) EAST
	place RED follower at (0,0) EAST
	place BLUE follower at (2,1) INNER
	place RED follower at (1,0) NORTH

Task 5: Use these last two sets of graphs above to test the function potential-locations-for-followers, which figures out where followers can be placed. [POINTS: 6]

Product: Mail a tar bundle with your revised implementation and the client test in a single directory. Formulate one test suite per method or function; document the test suites and test cases so that readers know what they test. -- Explain in a README file whether the construction of the client test discovered any errors, and if so, what kind.
