Checklist

General

Motivation and Context

This test is currently flaky: https://bamboo.ase.in.tum.de/browse/ARTEMIS-AEPTMA-DA-683/test/case/758873562
The problem is, that when the test tries to locate the users by their name, it seems they are not in the table, although the participation with Team Name does exist.
On bamboo it does not find the user sometimes:

    • I pushed a fix in commit <commit_id>, please review it.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and generate unit testing code.

213-214: Acceptable temporary fix for flaky tests, but consider future improvements

Commenting out the student username verification is a reasonable approach to fix the flaky tests, as team participation is still verified through:

  • Team name verification
  • Build plan checks
  • Repository commit history validation

However, to maintain comprehensive test coverage in the future, consider:

  1. Adding a more stable way to verify student participation
  2. Implementing retry logic with appropriate wait conditions
  3. Adding logging to help diagnose the root cause of the flakiness

Would you like assistance in implementing any of these improvements?
