# server-core/test-utils

*`packages/server/src/test-utils`*

## Purpose

Shared server-core test utility exports.

## Public surface

### [`AwaitNotificationError`](https://github.com/chughtapan/moltzap/blob/main/packages/server/src/test-utils/helpers.ts#L47)

*TypeAlias*

```ts theme={null}
export type AwaitNotificationError =
  | AwaitNotificationTimeoutError
  | AwaitNotificationClosedError;
```

): Effect.Effect<NotificationDelivery<D>, AwaitNotificationError>
```

Stream-based one-shot waiter. Consumes `client.subscribe(def)` via
`Stream.runHead`, failing with `AwaitNotificationTimeoutError` on timeout
and `AwaitNotificationClosedError` when the transport closed before a
matching frame arrived. Distinguishing close from timeout keeps a dead
connection from masquerading as a missing notification.
