[chrisknedl]

Checklist

General

• I tested all changes and their related features with all corresponding user types on a test server.
• 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

• Important: I implemented the changes with a very good performance and prevented too many (unnecessary) database calls.
• I followed the coding and design guidelines.
• I added multiple integration tests (Spring) related to the features (with a high test coverage).
• I documented the Java code using JavaDoc style.

Client

• Important: I implemented the changes with a very good performance, prevented too many (unnecessary) REST calls and made sure the UI is responsive, even with large data.
• I followed the coding and design guidelines.
• Following the theming guidelines, I specified colors only in the theming variable files and checked that the changes look consistent in both the light and the dark theme.
• I added multiple integration tests (Jest) related to the features (with a high test coverage), while following the test guidelines.
• I documented the TypeScript code using JSDoc style.
• I added multiple screenshots/screencasts of my UI changes.
• I translated all newly inserted strings into English and German.

Changes affecting Programming Exercises

• I tested all changes and their related features with all corresponding user types on Test Server 1 (Atlassian Suite).
• I tested all changes and their related features with all corresponding user types on Test Server 2 (Jenkins and Gitlab).

Motivation and Context

Closes #1402.

Description

A new object AssessmentNote is added to results. This object has a OneToOne mapping with the creator, a createdDate and string to represent the note itself. The result has a OneToMany relationship with the AssessmentNote, which is in fact an artificial OneToOne relationship, but the other annotation is needed to make lazy fetching work. The assessment notes have no reference to their owning result.

Note: There are many changes on the client-side since the way the save/submit of the assessment was handled is/was implemented slightly differently per exercise type. This PR additionally makes this as uniform as possible in the scope of this PR. There may be a possible future refactoring opportunity to deduplicate some of the previous implementations. This is out-of-scope for this PR, though.

Steps for Testing

Prerequisites:

• 2 Instructors
• 1 Student

1. Log in to Artemis
2. Navigate to Course Administration
3. Create a new programming exercise with
   • due date in the far future
   • manual assessment
   • online code editor enabled
4. Make a submission as a student
5. Change the due date to something like 3 minutes in the future
6. After the due date has passed, go to the assessment dashboard of the course

Testing session steps start here!

7. Start assessment for the exercise
8. Enter some text in the text box at the very bottom of the page
9. You should now be able to save, but not submit the assessment
   • Note: feedback, but empty assessment note can be submitted. I.e., there always has to be at least one feedback to be able to submit (previous behaviour as well), saving should be able after any changes.
10. Leave and re-enter the assessment view, the text should still be there after saving
11. Log in with another instructor, go to the ‘Course Management‘ → ‘Exercise’ → ‘Scores’ button on the exercise details page in order to view the assessment, and confirm that the note is still the same.

Another round of reapprovals needed: Again, only imports changed, though, due to #8492.

See 73bfd75 for changes.
