Grading

We will bias clarity over cleverness in evaluating your code. You should adopt a “teaching” mindset, always asking yourself, “How would I change what I have written to make it as easy as possible for someone else to understand my code without my direct assistance?” Refer to the standard Grading rubric if any portion of this rubric is unclear. _ Note that the standard rubric assumes a scale of 0-2 for each category_.

Category Weight Scoring Notes

Basic Preparation 2 0-1 Ready to go at the start of section

Cleverness 2 0-2 The hardest points on the rubric

Code Submission 4 0-2 Submitted correct content on time and to the correct location in the repository

Decomposition 4 0-2 Project is adequately decomposed to different classes and methods

Documentation 4 0-2 Comments for each class and each function are clear and are following style guides

Overview

This week, we will be focusing on refactoring your code from last week, adding good documentation, and also extending your library by adding two custom pieces and the controller component of MVC. Refactoring your library code and adding good documentation now – and throughout the assignment 1.X – will allow for easier and more efficient development in the coming weeks. By the end of the week, you should have a clean, easy-to-understand, and extensible library. For this assignment, you are required to use IntelliJ IDEA which has free and powerful refactoring tools available.

Assignment Format

This course is likely very different previous courses you have taken, in that we typically reuse your code from the previous week for each assignment. As such, don’t waste your time with messy code: focus on maintainability.

Read this entire page before beginning your assignment, and post on Piazza if anything is still unclear.

Part I: Refactoring & Polishing Test Suite

Agile Mantra “Make it work. Make it right. Make it fast.” · Kent Beck Read here and here for further discussion about this topic. You spent Assignment 1.0 making it work, now you will: · Refactor your code to make it right.

· Make it faster by using proper data structures. Before you begin refactoring, consider your test suite from Assignment 1.0. Did your moderator, the TAs, or your peers from discussion section suggest ways to improve the coverage of your test suite? Yes, yes you should have written your tests before implementing your functionality last week, but if for whatever reason, your test suite could be more thorough, spend some time enriching your test suite before you begin refactoring. Doing so will help you refactor more quickly, and to be more confident in the correctness of your refactorings. If you have not already done so, consider using the integrated code coverage features in IntelliJ IDEA to quantify how thorough your test suite truly is. You should refactor your code to eliminate any code smells (e.g. use communicative naming, decompose larger methods into smaller separate methods, etc), add missing tests, or other problems discussed in section.

Part II: Auto-generate Documentation Next, use Doxygen to auto-generate documentation for your library. You can find pre-packaged binaries here, or run the following command on the EWS machines or other Linux distros to get the latest build of Doxygen. I will assume this is run from the root directory of your project (i.e. from Assignment1.1/): wget http://ftp.stack.nl/pub/users/dimitri/doxygen-1.8.2.linux.bin.tar.gz && tar xf doxygen-1.8.2.linux.bin.tar.gz && cp doxygen-1.8.2/bin/doxygen ./ && rm doxygen-1.8.2.linux.bin.tar.gz && rm -rf doxygen-1.8.2

Then, to automatically configure and generate documentation for your project, simply run the following:

1. Run chmod a+rx doxygen && ./doxygen -g 2. Modify Doxyfile line 688, and change RECURSIVE from NO to YES 3. Run ./doxygen Doxyfile

If you have followed the instructions properly, your project directory should now contain autogenerated HTML & latex found under html and latex. Take a look at html/index.html in a browser to check it out!

This part should be relatively straightforward, and is intended to encourage you to expand on the documentation of your public methods and classes. Imagine you are handing this library to another developer, and that the PDF or HTML generated by Doxygen will be this programmer’s first contact with your library. Are there any thinly documented areas of the code? It should be more obvious using Doxygen which areas could use further explanation. If you do see these areas, expand on your documentation, and run Doxygen again to regenerate your documentation.

Please do not check your doxygen binary or generated documentation into SVN (the _latex, html, or doxygen files). This uses up a tremendous amount of space and resources in SVN, and will result in a deduction from Code Submission on the rubric. However, please ensure that Doxyfile, or whatever configuration file you use to generate your documentation, is committed to SVN. Without it, we cannot give you credit for the Doxygen-related requirements.

Part III: Two Custom Chess Pieces

If your code is properly refactored, this part should be a breeze. Your task is to create two custom chess pieces. All the usual chess rules apply to your custom pieces, for example, they are not allowed to move outside the board. For simplicity, your custom pieces do not have to

implement special moves, just as we ignored castling for king and rooks. You may find this article from wikipedia useful, but you are free to create your own movement.

Part IV: Static Graphical User Interface

Your task for this part is to implement a STATIC GUI. By static, we mean that your GUI should have ZERO USER INTERACTION. The only thing required for this week is to display the initial configuration of a chess board. Do not waste your time implementing chess moves, you may even lose points if you do. The point of this restriction is to give you a clearer understanding of the MVC architecture, by strictly separating the Model, View, and Control components. You implemented the chess model last week, this week’s focus is the view. Simply display a chess board with the normal set of chess pieces in their initial positions. Keep in mind, however, this does not mean you can simply display a static image in your JFrame.

GUI Builder Warning!

If you decide to use the UI builder IntelliJ for this assignment, be very careful.

Although the UI builder quickly generates Java GUIs, it produces very ugly code that will not meet the requirements for this assignment without modification. Most noticeably, it tightly couples the view with the controller, so significant refactoring of the autogenerated code will be required. In the staff’s opinion, it is more work to generate a UI automatically and refactor it properly than to build one from scratch.

Getting Started

GUI programming can be a potentially daunting experience. Below are some external resources to help get you going. Please start early and come to office hours or ask questions on Piazza if you are confused. These resources cover more than what you need for implementing a static GUI, but keep in mind NO USER INTERACTION this week. · MVC Wikipedia Article – The Wikipedia article on Model-view-controller architecture. · Sun JAVA GUI Tutorial – Sun’s tutorial on Java GUI programming. This is a great resource since it is straight from the source. · Model/View/Controller GUI – An introduction to the model view controller design scheme. Includes a Java GUI example. Especially relevant is section 3.1.2.0.1 Warning. · Crash Course in Java GUI – An introduction to Java GUI programming. The links on this site are actually powerpoint presentations. · Java GUI Examples – A number of examples using JFrame and JButton.

Part V: Manual Test Plan

GUI testing is difficult, especially just with unit tests. This week, in order to test your GUI, write a test plan including screenshots and specific steps for a human tester to follow – what a tester should do and what he/she should observe. Since your GUI this week is static, the test script should be very simple. You will be building on this test plan in the coming weeks.

Need help?

First, ask questions on Piazza. If you have a question, there is a pretty good chance someone else has the some one and an even better chance that someone else in the class or one of the TAs will be able to answer it for you. If you are still having a problem, email your moderator or one of the TAs to get advice. Remember, its best to ask questions early on so they have time to be answered. Don’t wait until the last second to get started then realize that you are confused. In general, we are flexible with interpretations of the assignment, as long as it does not trivialize any component of the assignment.
