Refactor

Once the functionality of code is known, the code can be tested or changed with understanding. This project will be using the SDL-Devil project.

In this assignment, you will build a test suite to verify that any changes made to a block of code do not break the code. Then, you will refactor the level statistics code in src/do_stat.c. As you make changes, you will need to test to verify that you have not introduced an incorrect refactor. You will need to create a script to diff your refactor output against the established output stats. Your test script should quickly identify if any errors are in the refactor.

Your goals:

1. Create a program to output level stats
2. Collect level stats before any other changes
3. Design a testing framework to validate your refactor
4. Refactor the stats code to a better state
   • Always make sure your refactor matches the original stat cases

I provide the fllowing:

• A set of levels to use for tests
• The results of my testing suite, so you can verify yours

A few notes:

• You must build the project for the x86 architecture (32bit). 64bit builds are not supported.
• There are many levels that fail to load properly. I have split the dataset into the following cases:
  • Descent 1 all levels
  • Descent 1 valid levels
  • Descent 1 error levels
  • Descent 2 all levels
  • Descent 2 valid levels
  • Descent 2 error levels
• You will need the SDL 1.2 libraries. The project is setup to check the root of the C drive for the libaries and includes.
• The project files are missing from the repo for some reason. Here they are. Extract to the sdldevil-code project directory.
• Windows will need the SDL.dll files in the same directory as the executable in order to run. So, copy the dll from C:/SDL-1.2.15/lib/x86/ to your build destination (probably vsproj/Debug/).

Rubric

Add harness to output stats	0 : No statistics	1 : Gets stats for a level
Test script to compare refactor output	0 : No script	1 : Comparison script
Script quickly indicates failures	0 : Report at end	1 : Immediate error abort
Test flexibiliti	0 : Hard coded	1 : Adapts to test data
Script correctly identifies errors	0 : Does not find errors	1 : Correctly finds errors
Levels of indention	0 : > 4 levels	1 : < 5 levels
Semantic meaning	0 : No semantic meaning	1 : All conditions have meaning
Complexity	0 : Hard to uunderstand code	1 : Code is simpler
Repetition	0 : Has repetition	1 : All repeated code abstracted out
