This is my automatic grading program for web sites that I am building initially for my Fall 2013 SI664 course. One day I will make it more general - but for now - it just needs to work for one class :)

For now this is simply prototype code that I am putting together - it is not ready to use at all. This is under construction.

If you want to see this autograder actually working, you can play online:

You could also play with my more advanced Python autograder:

• https://lti-tools.dr-chuck.com/pythonauto/lms.php
• https://github.com/csev/pythonauto

This will be built using two basic technologies: (1) IMS Learning Tools Interoperability for the LMS integration and grade flow and (2) Goutte to do the actual unit tests to evaluate the sites and compute the grades. Here are some relevant URLs:

Goutte and BrowserKit:

As part of this code development, I am re-working the IMS LTI code to be (a) scalable, multi-tenant-aware, and more elegant and (b) start laying the ground work for supporting IMS LTI 2.0 when it comes out.
