### Issue 1 of 1
src/app/[username]/components/ErrorMessages.test.tsx:34-37
**Section Message Pairing Is Untested**

The multiple-error test checks each section and each message as separate text nodes. If the component renders the API section with the Database message and the Database section with the API message, all four assertions still pass, so this test misses the visible section-to-message mismatch.

```suggestion
    expect(screen.getByText("API:").closest("div")).toHaveTextContent("API: Failed to fetch data");
    expect(screen.getByText("Database:").closest("div")).toHaveTextContent("Database: Connection timeout");
```

Warning

Review limit reached

@is0692vs, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 49 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Code Review

This pull request adds a new test file ErrorMessages.test.tsx to verify the behavior of the ErrorMessages component under various conditions, such as empty, undefined, single, and multiple error states. Additionally, it updates vitest.config.ts to exclude the ErrorMessages.tsx component from coverage thresholds. There are no review comments, so I have no feedback to provide.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.

Section Message Pairing Is Untested

The multiple-error test checks each section and each message as separate text nodes. If the component renders the API section with the Database message and the Database section with the API message, all four assertions still pass, so this test misses the visible section-to-message mismatch.
