Question

Assignment Scope       

For this assignment students will experience changing requirements resulting in modifying the original design. This is real world experience and is intentionally incorporated into projects every semester to expose students to the need to be flexible in software engineering. After initial project design of a project, when software engineers delve into writing the source code, it frequently exposes gaps in previous assumptions.

Additionally, software engineers will write some test code for the backend development that eventually will not be used in the final project or also known as thrown away. We do this to make sure our backend logic works before we add a user interface. We will also incorporate this methodology for this assignment of the project.

Finally, software engineers always perform regression testing after modifying source code. Regression testing is a type of software testing which verifies that software which was previously developed and tested still performs the same way after it was changed or interfaced with other software. Changes may include software enhancements, patches, configuration changes, etc.

The goal is to simulate the foundation of the components of the game MasterMind by creating a Codemaker, Codebreaker, and the Game; this includes:

1. Allow the code breaker to attempt guessing the secret code.

2. Have the code maker respond to the code breaker’s attempt.

a. If the correct color is in the correct position, the code maker’s response should include a red peg

b. If the correct color is in the wrong position, the code maker’s response should include a white peg

c. If the color is not correct no pegs are used

d. Red pegs are presented first, then the white pegs

3. Limit the number of attempts to 10 guesses, if the code breaker guesses the code, they win the game, if the code breaker does not guess the code within 10 guesses, they lose the game.

To accomplish this, write the follow source code:

1. Reference the tasks below for the specifics of the source code requirements.

2. Compress a project and submit to Webcourses

3. Decompress compressed project and verify it is a Netbeans project

b. Add the codebreaker’s guess at this index to the Set that stores the evaluated pegs

2. Use an enhanced for loop using the codebreaker’s attempt as the collection object

a. Check if the secret code ArrayList contains the current element of the codebreaker’s attempt (Hint: class ArrayList has a handy method .contains())

i. Loop through the max pegs as defined in our Constants.java class

1. Check if the secret code ArrayList is NOT equal to the codebreaker’s attempt at the specific index AND the secret code ArrayList contains the codebreaker’s attempt at the specific index AND the pegs evaluated Set does NOT include the current codebreaker’s attempt at the specific index

a. If true, then increment the white pegs counter

b. Add the current index of the codebreaker’s attempt to the ArrayList that stores the evaluated pegs

i. For each red peg, add to the member variable codemakerResponse Color.RED

ii. For each white peg, add to the member variable codemakerResponse Color.WHITE

iii.Red is always first, then white!

iv. Use an enhanced for loop to output to the console the codemaerker’s response

Game class

a. Call method play()

Expected outcome

Test Case 1

Run application – start the game

JOptionPane.showMessageDialog() displays similar to figure 1

Test Case 2

Run application – codemaker generates secret code

The console window should be similar to figure 2

Java does NOT automatically translate its Color objects to a String value, rather it prints the RGB code of the color.                   

Test Case 3

Run application – codebreaker prompted for their guess

The console window should be similar to figure 3

Test Case 4

Run application – codebreaker entries acknowledged

The console window should be similar to figure 4

Test Case 5

Run application – codemaker response

The console window should be similar to figure 5
