General

• Language: I followed the guidelines for inclusive, diversity-sensitive, and appreciative language.
• I chose a title conforming to the naming conventions for pull requests.

Server

• I strictly followed the principle of data economy for all database calls.
• I strictly followed the server coding and design guidelines.
• I documented the Java code using JavaDoc style.

Motivation and Context

As part of the server modularization, we "facade" the service/repository declaration and method calls to module-external classes via a module API provided by the respective module.

Description

These changes add the module API for text exercises.

Out of scope: Adding a PROFILE_TEXT to disable the module on server start. This requires a lot of frontend changes and testing.

Steps for Testing

Basically try to test all the functionality of text exercises regarding submissions, courses, and import/export.

1. Log in to Artemis
2. Create a text exercise
3. Update the exercise
4. Make a submission
5. Create an example submission
6. Import the student submission as example submission
7. Export the example submissions
8. Import the exercise into a new course
9. Delete the exercise in both courses

Exam Mode Testing

1. Log in to Artemis
2. Create a regular text exercise
3. Create an exam
4. Create a text exercise in the exam
5. Import the created text exercise from 2 into the exam
6. Participate in the exam and make submissions

🟩: Works well
🟨: Works partially
🟥: Doesn't work

I tested the following:
🟨 Creating a text exercise
🟨 Edit the text exercise
🟨 Create an example submission (When changing the Assessment Training, then clicking on Update example submission, the view only gets updated when I reload the page, can we make it so that on clicking update submission, the view also gets updated. Also when I add an assessment when the Assessment Training is Assess Correctly, then change to Read and Confirm then back to Assess Correctly, the assessment is gone. Also the assessment is also gone when I click on Update example Submission then reload without changing anything. This is probably not related to this PR, I think I would mention this in an issue)


🟥 Import the student submission as example submission (I made a submission with test user 1 and another with test user 20 but when trying to import submissions, it says that it can't find the students' submissions)


🟥 Export the example submissions (I couldn't find the button to export example submissions)
🟨 Import the exercise into a new course
🟩 Delete the exercise in both courses

When clicking into create new or edit or import a text exercise, I had these problems. However the creation or the changes while edit as well as the import still works, for the import I have to reload the page and then go back to the Exercises Overiview to see the newly imported exercise

🟩 Create an exam
🟩 Create a text exercise in the exam
🟩 Import the created text exercise from 2 into the exam
🟨 Participate in the exam and make submissions: When I try to submit it early I got a Bad Request, however it still goes through
