This is the 2 The Scenario
Your task will be to process output from a maze-generating program in order to create a
smoother, more appealing output for terminal display. The maze-generating program has
already been created for you; your task is solely to modify the output. Currently, the program
generates a simple maze and displays the maze in a format made up only of ‘+’, ‘-‘ and ‘|’
characters. While this is suitable for simple display, it is not the most intuitive to read for a
human and your task is to improve on this using Box-Drawing Characters (which are discussed
in more detail in section 2.1).
As an example, here is the kind of input you can expect (on the left) and how your program
should output the maze (on the right):Note that the primary display for this will be on the terminal. You may 2.1 Maze Structure
The Wikipedia article, but you will only need a
small subset of characters for this assessment. A maze may be made up of the following
characters (and their associated codes):
■ Full lines:
▸ ┃ (U+2503)
▸ ━ (U+2501)
■ Half lines (i.e. for open ends of walls):
▸ ╸ (U+2578)
▸ ╻ (U+257B)
■ Corners:
▸ ┏ (U+250F)
▸ ┛ (U+251B)▸ ┓ (U+2513 - Only used for the outside, top-right border)
▸ ┗ (U+2517 - Only used for the outside, bottom-left border)
■ Intersections:
▸ ┻ (U+253B)
▸ ┣ (U+2523)
If you happen to be familiar with mazes, this might not seem like a complete set, as the lines
are ever only being drawn up and right. However, the algorithm for creating the maze will
never generate a case where other characters (such as ╋ or ┳) would be used. Only the
characters listed above will be used.
The maze is structured as a 2D array, where each ‘cell’ is either linked or not linked to one of
its neighbours. As an example, if the program were to generate a “maze” where each cell was
linked to every neighbour it would generate (and your expected output would be):
… if no cell were linked, the following maze would be generated (and your expected output
would be):In order to determine which is the appropriate character, you will need to inspect a cell in this
2D array and look at each of its neighbours.
A full horizontal line can be determined in the following case, because the corner character
(‘+’) has walls (‘-‘) on the left and right, but not up or down:
NoteHINT: It is suggested that you read from the source maze and write to an output maze:
do not overwrite the source maze, as you will lose/overwrite information that may be
valuable for both earlier and later cells.
2.2 Maze Generating Program
As part of this assessment, you will be provided with a simple program that generates output
as outlined above. You are encouraged to use this program to become familiar with the
output and to use cases generated by this program to assist in testing (but they are NOT
suRuby. You do not need to learn this
language to use the program. There are four source code ■ binary_tree_demo.rb
■ binary_tree.rb
■ grid.rb
■ cell.rb
To run the program, you use the following command on either the lab machines or VMWare
Horizon:
ruby -I. binary_tree_demo.rb
The program will output the maze to the terminal and exit. You may wish to save the output to
a ruby -I. binary_tree_demo.rb > maze_output.txt
(Any name can be specimaze_output.txt)
3 The Tasks
For this assignment, you will create documentation for, and be assessed on, these tasks:
■ Version Control
■ Modularity Design
■ Modularity Implementation
■ Test Design■ Test Implementation
■ Summary of Work
ALL these tasks will primarily be assessed through your documentation. All code that you
create will, however, need to also be submitted to verify your work has been done.
3.1 Version Control
As part of this assignment, you are to apply version control to keep track of your work.
■ Create a short plan, identify what branches you will need, why you need them, and
when the branches will be merged.
■ Create a Git local repository for use throughout this assessment. The repository name
should be in the format of __ISE_Repo
▸ e.g. Brower_Arlen12345678_ISE_Repo
■ Commit all code and documents you create in the assessment
▸ You are expected to use meaningful commits; while there is no hard rule about
what each commit should contain, you are expected to show your ability to use
version control meaningfully. Marks are not awarded for number of commits.
■ Include evidence of your use of version control, such as an image of the log
Any other discussion or explanation on your use of version control should also be included in
the documentation.
Warning
Do not use GitHub, BitBucket, or any other similar online repositories. Doing so runs the
risk of potential collusion investigations. Similarly, do not upload your code to online
repositories even after the assignment due date; other students may have extensions or
deferred assessments.
3.2 Modularity Design
With the given scenario, you are to identify the most suitable modules you will need for your
software to achieve the required functionality, considering the good modularity principles
discussed in lectures/worksheets. You are to:■ Write down module descriptions for each module you decide to implement.
Descriptions should include:
▸ A meaningful name
▸ A clear and detailed explanation on the intended task of the module
▸ Imports, if any
▸ Export, if any
■ Explain your design decisions and how they conform to good modularity principles
Note
It’s rare that you will get the design 100% ideal from the very start. Design is often
iterative. This is actually a very good, interesting thing to include in your documentation
for this assessment. If you 3.3 Modularity Implementation
You are to implement the software using your designs, review the code you have written, and
refactor it. As part of this task, you should:
■ Implement the modules designed in the previous section
▸ You may use Java or Python for your implementation
▸ Your code must run on the lab machines or VMWare Horizon
■ Create a short review checklist to determine if you have followed good modularity
principles. You are expected to cover all basic guidelines covered in lecture 7.
■ Review your code using the prepared checklist, identifying any issues. You must use the
format suggested in worksheet 7 to record your results. Each module must be
reviewed.
■ If you have identi▸ If you refactor your code, explain how it is improved;▸ If you do not refactor your code, justify your decision
■ After refactoring, revise your preliminary descriptions of your modules.
■ At every stage, you should be making changes and committing those changes to the
repo whenever you have made a step you are satis3.4 Test Design
You are to design tests using both black box and white box methodologies.
■ Black box test design:
▸ For each module, according to module descriptions, design suitable test cases.
▸ Describe how you decide upon your test values for each test case
▸ Test cases should each also describe their expected output or behaviour
■ White box test design:
▸ Identify at least two modules where white-box testing will be bene▸ Design test cases to cover functionality of the selected modules using white box
testing
▸ You must test at least two di▸ Describe how you decide upon your test values for each test case
▸ Again, be comitting these test cases to the repo as you write and are satis3.5 Test Implementation
Implement your test designs in either Python or Java. You may use test ■ Identify the actual results for each test case
■ Identify any failures, and attempt to improve your code
▸ Be sure to document this process, as it again makes for useful discussion for this
assessment3.6 Summary of Work
You are to produce a table clearly showing your overall module design and the ■ Each module should have one row
■ For each module, you should identify if the following work has been done:
▸ Whether or not the module is complete;
▸ Whether or not the module’s tests have been designed;
▸ Whether or not the module’s tests have been implemented;
▸ Whether or not the module’s tests are successful
Additionally, your submission must include a short video roughly two minutes in length
demonstrating that your code is working. More information on this video is included in section
5 of this document.
4 Documentation
