A sample C++ autograder repo to show how diff-based autograding works. The corresponding assignment can be found at https://github.com/ucsb-gradescope-tools/sample-cpp-assignment.
Editing bash scripts (e.g. diffs.sh) on Windows will convert the line endings to Windows style, causing the script to be unusable by the Docker container. Either edit the files in a Unix/Mac environment or use a tool to de-convert the line endings BEFORE uploading your autograder.zip.**
On MacOS, g++ automatically links to clang++. Hence, if you are
doing anything involving clang or clang++, it might work on MacOS,
then fail to work once you load the script to Gradescope. Be sure in
that case that your apt-get.sh includes an install of the appropriate
clang++ toolchain.
Any extra files (e.g. a Makefile) that should be in the same directory as the student submission while the submission is being built. In this repo, the EXECUTION-FILES directory has the Makefile from the assignment repo.
When converting an assignment from submit.cs, any files that were "build files" on submit.cs go into this directory, along with the Makefile for the assignment.
Any extra files (e.g. data files) that should be in the same directory as the student submission while the submission is being executed. In this repo, the EXECUTION-FILES directory has input.txt file from the provided-files directory in the assignment repo.
A reference solution which will be used to generate the expected outcome for all tests. Like student solutions, this solution will be run with all files from EXECUTION-FILES in the same directory.
A bash script that creates the expected test output using the reference solution. Leave this unchanged when creating your own autograder.
A bash script for installing any necessary dependencies for the assignment, e.g. g++.
A bash script describing the tests to be run. See this page for further documentation.
A bash script for generating the results of the student submission. At the top of this file, you must specify what student files should be copied from /autograder/submission for testing. For example, the grade.sh in this repo begins with:
cp /autograder/submission/helloWorld.cpp . cp /autograder/submission/helloStderr.cpp .
etc.
