Motivation and Context

Description

This PR adds a programming language template for JavaScript.

The template runs tests using Jest. Student code and test code is transpiled with Babel to enable the use of ES6 modules.

The dependencies are cached in the docker image.

Steps for Testing

Prerequisites:

• NodeJS installed
• 1 Instructor
• 1 Course
• 1 Student

Setup

1. Log in as Instructor to Artemis
2. Navigate to Course Administration
3. Create a new Programming Exercise
4. Select Javascript as the programming language
5. Fill out the required fields and click on Generate
6. The Template Result should build and fail with 10 test cases
7. The Solution Result should build and pass with 10 test cases

Local Test

8. Clone the Test Repository into test/
9. Clone the Solution Repository into test/assignment/
10. Enter the test/ directory
11. Run npm ci
12. Run npm test
13. The tests should pass

Exercise Participation

14. Log in as a Student
15. Navigate to the exercise
16. Start the exercise

Works on Ts4, no idea though why it does not deploy sometimes.

Nice addition ☺️ Could not test all CI template (e.g., GitLab) but they all seem logical 👍
