Unit tests for Udacity CS373 homeworks

Requirements

  • git (to clone the repo ;) )
  • python-2.x (tested with 2.7.2, but probably works with 2.6 too)
  • text editor of your choice

Quick usage

  1. Clone the repo (if you haven't done already):

    $ git clone git://github.com/DirtYiCE/cs373-tests.git
    $ cd cs373-tests
    
  2. Make sure you have set $EDITOR to your favourite text editor, then issue:

    $ ./test.py <homework_number> edit
    

    Where <homework_number> is in format like 1.4 for the 4th question in the first homework. You can also copy <homework_number>/base_code.py to <homework_number>/code.py (if exists, otherwise just create a new file), then open it with your editor.

    It may be an empty file, do not worry. It will set the given variables to the given values before executing your code. You actually only have to write the part after the "do not modify anything before" lines, and you also don't have to print it (just place in the correct variable). If you're not sure, open <homework_number>/template.py and search for # !code!. Your code will be executed like you placed your code there.

    For example, given a task to add two numbers together, you would get something like this to edit:

    a = 4.0
    b = 5.0
    
    # ENTER CODE BELOW
    
    c = 0.0
    
    
    
    # You must print it with the following code:
    
    print(c)
    

    Then, when you run ./test.py <num> edit, you only have to enter

    c = a + b
    

    And it will work like you just inserted it after c = 0.0.

  3. When you think you should test your code, with the examples given in the homework assigment, run:

    $ ./test.py <homework_number>

    If all test passes, you will see an OK at the end of output. Otherwise it will tell you which tests failed, the expected and your output.

  4. When you are done, simply paste your code into the correct place in the web interface. Alternatively, you can use

    $ ./test.py <homework_number> format
    

    to print your code (to the stdout) with all the required header and footer stuff. If you use run instead of format, it will run the code in python, just to check if everything is right.

    You will probably want to run the code before saving it (in the browser), just in case Udacity's python handles somehing differently.

Available commands

General syntax is:

$ ./test.py <homework_number> [command] [arguments]

command defaults to test when not specified. Available commands:

  • edit: open your solution (<homework_number>/code.py) with $EDITOR
  • zap: deletes your solution
  • test: run the tests. Arguments you pass will be handled by python unittest.
  • format: place headers and footers around your solution, then print to stdout.
  • run: executes the output of format

*/template.py files are from Udacity. */testcase.py also tend to contain some Udacity code. Other files were written by me, and you're free to do whatever you want do with them. They are available under the terms of WTFPL, if you like that better.

Notes

This program doesn't contain the solution to the homework, nor tells you if they're correct. It justs tests that the example inputs given in the assigment produces the same output as in the video. It only saves you from manually typing the inputs then comparing the numbers (which is quite error prone). Otherwise, it gives you no advantage.
