go-autograder

A template for building Gradescope autograders for Go projects.

Getting started

This autograder works by running all Go tests in a student's submission, parsing the results from stdout, and generating a results.json file in Gradescope's specified format. Only tests that you specify in autograder.config.json are parsed and sent to Gradescope.

When the autograder runs, the student's submission will be copied into /autograder/source/submission. You can make any necessary changes to a student's submission -- such as copying in test suite files -- before the autograder runs by adding shell commands to run_autograder in the indicated area.

File hierarchy

• autograder.config.json - A JSON file that specifies config options for your autograder suite. Here is where you will define the names of tests and associated point values.
• setup.sh - A setup (Bash) script that installs all your dependencies. Gradescope uses Docker running on Ubuntu 18.04 images, so you can use apt, or any other means of setting up packages. By default, it simply uses apt-get to install Go.
• run_autograder - An executable script, in any language (with appropriate #! line), that compiles and runs your autograder suite and produces the output in the correct place.
• src/test_runner - A Go module containing the code responsible for running go test on a student's submission, parsing the results from stdout, and returning a results.json file in Gradescope's specified format.

autograder.config.json

This JSON file is where you will configure your autograder for your particular assignment. In this file, you must specify the names of the tests you want to use for grading, along with associated point values.
