All projects in this course will be autograded after you submit your code through the handin website. For all projects you can submit as many times as you like until the deadline. Every project's release includes its autograder for you to run yourself. This is the recommended, and fastest, way to test your code, but keep in mind you need to submit into the handin system to get your grade registered.
To get you familiarized with the autograder, we will ask you to code, test, and submit solutions for three questions. You will submit your files on the last tab in this sequence (scroll up and click on the right most tab).
You can download all of the files associated the autograder tutorial as a zip archive: tutorial.zip (note this is different from the zip file used in the UNIX and Python mini-tutorials, python_basics.zip). Unzip this file and examine its contents:
[cs421-ta@nova ~]$ unzip tutorial.zip [cs421-ta@nova ~]$ cd tutorial [cs421-ta@nova ~/tutorial]$ ls VERSION addition.py autograder.py buyLotsOfFruit.py grading.py projectParams.py shop.py shopSmart.py testClasses.py testParser.py test_cases textDisplay.py tutorialTestClasses.py
This contains a number of files you'll edit or run:
addition.py:
source file for question 1
buyLotsOfFruit.py:
source file for question 2
shop.py:
source file for question 3
shopSmart.py:
source file for question 3
autograder.py: autograding
script (see below)
and others you can ignore:
test_cases:
directory contains the test cases for each question
grading.py:
autograder code
testClasses.py:
autograder code
tutorialTestClasses.py:
test classes for this particular project
projectParams.py: project
parameters
The command python autograder.py
grades your solution to all three problems. If we run it before
editing any files we get a page or two of output:

To register your grades, make sure to follow your instructor's guidelines to receive credit on your project.
For each of the three questions, this shows the results of that question's tests, the questions grade, and a final summary at the end. Because you haven't yet solved the questions, all the tests fail. As you solve each question you may find some tests pass while other fail. When all tests pass for a question, you get full marks.
Looking at the results for question 1, you can see that it has failed three tests with the error message "add(a,b) must return the sum of a and b". The answer your code gives is always 0, but the correct answer is different. We'll fix that in the next tab.
