Problems mocking MockConnection error response

I’m testing http service in Angular2. I want to test the server, the server responds ‘Unauthorized Error’. In test I used this code:

this.backend.connections.subscribe(
            (connection: MockConnection) => {
                console.log("Connection");
                connection.mockError(<any>new Response(new ResponseOptions({status: 401, body: 'error'})));
            }
        );

In test I used handleError from angular.io..

It is the wrong decision. Tell me how to test this situation.
