+     * Observe the CommandSucceededEvent event for the find command and extract the cursor's ID and namespace from the response document's cursor.id

+     *
+     * Assert that the cursor ID and target namespace in the outgoing command match the values from the find command's CommandSucceededEvent.
+     * When matching the namespace, note that the killCursors field will contain the collection name and the database may be inferred from either
+     * the $db field or accessed via the CommandStartedEvent directly.
+     *
+     * Finally, assert that the killCursors CommandSucceededEvent indicates that the expected cursor was killed in the cursorsKilled field.
+     *
+     * Note: this test assumes that drivers only issue a killCursors command internally when destroying a cursor that may still exist on the server.
+     * If a driver constructs and issues killCursors commands in other ways (e.g. public API), this test MUST be adapted to test all such code paths.
