Jest doesn't exit after tests completed

This happens for various tests even though:
```js
afterAll(async () => {
await podProvider.stop();
await appServer.stop();
});
```
are called.

Jest says: ``This usually means that there are asynchronous operations that weren't stopped in your tests. Consider running Jest with `--detectOpenHandles` to troubleshoot this issue.`` Though when adding the flag, there is no additional information provided.

Start by locating the test suites where `afterAll` calls `podProvider.stop()` and `appServer.stop()`, then trace setup/teardown around those helpers. Check Jest config and any shared test bootstrap files for other long-running servers, DB clients, timers, or sockets that are not closed. Re-run the suite with `jest --detectOpenHandles` as the issue already suggests, then verify no extra handles remain. Issue is done when the suite exits normally and Jest no longer shows the async operations warning.
