autograding CS labs

[melodyc_lam]

Hi, ya'll. I'm trying to develop an autograding program for CS labs written in Java in my CS class, instead of just manually inspecting code in Speedgrader. I know there are other autograding programs out there and other alternatives to autograding with Canvas (like GitHub Education + Travis CI), but I'd like to develop my own as a good exercise in programming.

I was wondering if anybody has tried making one for Java code. I know K-State has a Java wrapper for the API but it's not complete and won't have 100% parity with the REST API that Canvas supplies. The other alternative is to use Python and maybe call the JTest suite using OS calls.

The general workflow for this project is to

1) download submissions as a ZIP file

2) unzip file and run JTest suite on each student's file

3) gather results into a text file, parse text file and change grades based on results (missing/won't compile = 0, failed test = 1/2 credit, etc, etc).

Thanks in advance!!

Any updates on this endeavor? I'd like some autograding capabilities for my Python course and Java course.

I am also interested in using such a tool for my C and Java courses. Are there any updates?

If you can use an LTI, look at Web-CAT (https://web-cat.org). It is based on test-driven development, where students can be evaluated on how well they code and how well they test their code, as well as against JUnit tests written by the instructor. Web-CAT can pass back completed grades to Canvas. It supports a variety of languages including Java, C++ and Python. We use it for our Java CS1 and CS2 courses, as well as our data structures courses, so it supports a wide variety of exercise types. Ping me direct if you want to know more.
