Moodle JUnit Exercise Corrector (MoJEC) Plugin
A Moodle plugin to assist teachers correcting JUnit exercises.
This plugin allows students to submit their Java exercises, let them be tested against a set of JUnit tests (that have been priorly provided by the teacher) and receive immediate feedback on the test results.
For this to work, the plugin communicates with an external webservice providing essentially the following services on the given paths:
- POST /v1/unittest: Expects the assignment id and a zip file containing the unit test files as http post parameters.
- POST /v1/tasks: Expects the assignment id and a zip file containing the java files that should be tested as http post parameters. Extracts the zip file, compiles the java files and runs the tests (provided via /v1/unittest). Returns the results in form of JSON.
- DELETE /v1/unittest?assignmentId={id}: Triggers the deletion of the test files.
See here for an implementation of the webservice: MoJEC Backend
Installation/Configuration
- Install this plugin by using the Moodle web installer, or by extracting the plugin archive to {Moodle_Root}/mod/assign/submission/mojec and visting the admins notifications page.
- Visit the plugin's settings and configure the base URL of the web service to use.
The required web service can be found at: https://github.com/HFTSoftwareProject/MoJEC-Backend and https://hub.docker.com/r/hftstuttgart/mojec-backend/ - Done!

you can find example unit tests and example files-to-test at: https://github.com/HFTSoftwareProject/MoJEC/tree/master/exampleData
I just tested it with those files and the docker container from: https://hub.docker.com/r/hftstuttgart/mojec-backend/
I pulled this docker container with:
docker pull hftstuttgart/mojec-backend
and start it with:
docker run -p 8080:8080 -d --name mojec-backend hftstuttgart/mojec-backend:latest
Then it should be available on port 8080.
You should also be aware of this issue: https://github.com/HFTSoftwareProject/MoJEC-Backend/issues/6
Which means you are not allowed to organize the unit tests within a package structure. You need to use the "default" package. The files-to-test can be put into packages.
But this shouldn't cause a problem when uploading the test files but when running the tests i.e. when uploading tasks.
