Development: Fix exam assessment e2e tests failing

[SimonEntholzer]

Checklist

General

• This is a small issue that I tested locally and was confirmed by another developer on a test server.
• I chose a title conforming to the naming conventions for pull requests.

Motivation and Context

The exam assessment e2e tests broke due to the logic changes in the student exam creation in #9123, as there is now a race condition, when the student exams are generated automatically. The playwright tests registered users before creating exercises, which lead to the student exams showing up without any exercises to the user.

Description

Simply registering the students after creating the exercises, solves the issue.

Steps for Testing

Prerequisites:
Run the playwright e2e test and make sure no tests fail.

Walkthrough

The changes in this pull request enhance the assessment process in the ExamAssessment.spec.ts and ExamDateVerification.spec.ts files by adding a line to register a student for an exam within the respective test cases. This ensures that studentOne is registered after the exam is created, maintaining the integrity of the exam setup. The overall structure and logic of the tests remain intact, with the addition of feedback mechanisms and time management using dayjs. Playwright continues to be utilized for browser interactions.

73-73: Excellent addition to resolve the race condition.

This line ensures that the student is registered for the exam after the exam and exercise group are created, but before generating individual exams. This change directly addresses the issue mentioned in the PR objectives, where students were unable to see exercises in their exams due to a race condition.

---

110-110: Consistent application of the fix across test cases.

This change applies the same solution as in the previous test case, ensuring that the student is registered for the exam at the correct point in the setup process. This consistency is crucial for maintaining the integrity of the test suite and addressing the race condition issue across different scenarios.

---

73-73: Overall, these changes effectively address the race condition issue.

The two identical additions in different test cases provide a consistent solution to the problem of students not seeing exercises in their exams. These changes align perfectly with the PR objectives and should resolve the failing e2e tests.

To ensure the effectiveness of these changes:

Run the following script to verify that these are the only instances where student registration is added, and that they are placed correctly in the test setup process:

This will help confirm that the fix has been applied consistently and correctly across all relevant test cases.

Also applies to: 110-110

Line range hint 1-478: Consider adding a specific test for the race condition.

While the change effectively addresses the reported issue, it might be beneficial to add a specific test case that verifies the resolution of the race condition. This would ensure that future changes don't inadvertently reintroduce the problem.

Consider adding a test case that:

1. Creates an exam with multiple exercises
2. Registers a student
3. Generates individual exams
4. Verifies that the student can see all exercises associated with their exam

This would provide an extra layer of confidence in the fix and serve as documentation of the resolved issue.

349-349: LGTM! This change addresses the race condition issue.

The addition of await examAPIRequests.registerStudentForExam(exam, studentOne); at this point in the prepareExam function effectively resolves the race condition mentioned in the PR objectives. By registering the student after creating the exam and exercise, but before generating individual exams, we ensure that the student will have access to all relevant exercises when the exam is generated.

This change aligns perfectly with the PR's goal of modifying the order of operations in the test setup to prevent scenarios where registered students were unable to see exercises associated with their exams.
