Hey - I've found 1 issue, and left some high level feedback:
- For the toggle button, consider exposing its open/closed state to assistive tech (e.g.,
aria-pressedoraria-expanded+aria-controls) instead of a staticaria-label="Toggle notifications", so screen readers can tell whether the panel is currently open. - Using
aria-live="polite"directly on the numeric badge may not provide enough context for screen readers; consider wrapping the count in a live region with descriptive text (e.g., "You have X unread notifications") or adding an offscreen label so announcements are meaningful. - Several behavior-focused tests for NotificationCenter (unread count updates, receiving notifications, mark-as-read, dismiss) were removed; if those flows are still supported, it may be worth keeping or adapting those tests to ensure the WebSocket-driven behavior remains covered under the new setup.

## Overall Comments
- For the toggle button, consider exposing its open/closed state to assistive tech (e.g., `aria-pressed` or `aria-expanded` + `aria-controls`) instead of a static `aria-label="Toggle notifications"`, so screen readers can tell whether the panel is currently open.
- Using `aria-live="polite"` directly on the numeric badge may not provide enough context for screen readers; consider wrapping the count in a live region with descriptive text (e.g., "You have X unread notifications") or adding an offscreen label so announcements are meaningful.
- Several behavior-focused tests for NotificationCenter (unread count updates, receiving notifications, mark-as-read, dismiss) were removed; if those flows are still supported, it may be worth keeping or adapting those tests to ensure the WebSocket-driven behavior remains covered under the new setup.
## Individual Comments
### Comment 1
<location path="src/components/notification/NotificationCenter.tsx" line_range="102" />
<code_context>
<Badge
variant="destructive"
className="absolute -top-1 -right-1 h-5 w-5 rounded-full p-0 text-xs flex items-center justify-center"
+ aria-live="polite"

{unreadCount}
</code_context>
<issue_to_address>
**suggestion (bug_risk):** Reconsider using `aria-live` on the badge alone; screen readers may announce only a bare number.
On some screen readers, this pattern causes only the number change to be announced, without any “unread notifications” context. Consider instead using a visually hidden live region that includes descriptive text (e.g. “4 unread notifications”), or updating the toggle button’s `aria-label` to include the count so announcements remain understandable.
Suggested implementation:
```typescript
size="icon"
className="relative"
onClick={() => setIsOpen(!isOpen)}
aria-label={
unreadCount > 0
? `${unreadCount} unread notifications`
: "No unread notifications"
}
>
<Bell className="h-5 w-5" />
{unreadCount > 0 && (
<>
<Badge
variant="destructive"
className="absolute -top-1 -right-1 h-5 w-5 rounded-full p-0 text-xs flex items-center justify-center"
>
{unreadCount}
</Badge>
<span className="sr-only" aria-live="polite">
{unreadCount} unread notifications
</span>
</>
)}
```
1. This assumes you already have a global `sr-only` utility class available (common with Tailwind). If not, you should add one (e.g. in your global CSS) that visually hides content but keeps it available to screen readers.
2. If the button’s label semantics need to emphasize its “toggle” behavior, you can adjust the `aria-label` string to something like `"Toggle notifications, ${unreadCount} unread"` while keeping the live region as implemented above.

Bug: The unread notification count Badge is conditionally rendered, preventing screen readers from announcing the first notification because the aria-live region is not in the DOM beforehand.
Severity: MEDIUM
Suggested Fix
Instead of conditionally rendering the Badge, keep it in the DOM and use CSS to hide it when the count is zero (e.g., display: none or a visibility class). This ensures the aria-live region is always present, allowing screen readers to announce content changes, including the transition from zero to one.

Potential issue: The `Badge` component, which displays the `unreadCount`, is
conditionally rendered only when `unreadCount > 0`. The `aria-live="polite"` attribute
is on this `Badge`. For an ARIA live region to announce changes, it must be present in
the DOM before the content update occurs. When the first notification arrives, the count
changes from 0 to 1, causing the `Badge` to be inserted into the DOM for the first time.
Screen readers do not announce the creation of a new live region, only content changes
within an existing one. Consequently, the most critical announcement—the arrival of the
first notification—will be missed by screen reader users. The announcement will only
function correctly for subsequent notifications (e.g., when the count changes from 1 to
2).

Bug: The aria-live attribute on the notification Badge is implemented incorrectly by being nested within a button and conditionally rendered, breaking accessibility for screen readers.
Severity: MEDIUM
Suggested Fix
To fix this, move the aria-live region to a separate, visually hidden element outside the <button>. This element should be rendered unconditionally so that it's always present in the DOM, allowing screen readers to reliably announce changes to the unread count.
Prompt for AI Agent

Location: src/components/notification/NotificationCenter.tsx#L98-L103
Potential issue: The notification badge's `aria-live` attribute is implemented in a way
that violates WAI-ARIA accessibility best practices, leading to unreliable announcements
for screen reader users. The `aria-live` region is placed inside an interactive
`<button>` element, which can cause unpredictable behavior. Furthermore, the badge
component is conditionally rendered only when `unreadCount > 0`. An `aria-live` region
must be persistently in the DOM before its content changes to be announced reliably.
Because the element is created at the same time the count appears, the initial change
from zero is likely to be missed by screen readers.

This PR improves the accessibility of the NotificationCenter component by adding mandatory ARIA labels to all icon-only buttons and ensuring the unread notification count is announced to screen readers. It also fixes a regression in the testing infrastructure that was preventing unit tests from running.
