Error when executing Unit Test for AnjularJS

Iam new to AngularJS. Iam attempting to write a UTP using Karma. The code goes like this:

(function () {
    'use strict';

describe('Document Service', function () {
    var SEARCH_URL = '/documents';
    var DETAILS_URL = '/documents/111111';
    var DOC_HISTORY_URL ='/documents/history';

    var Document_global;
    var Document;

    beforeEach(function() {
        module( 'lens.globals' );
        module( 'lens.util' );
        module( 'lens.integration' );
        module( 'lens.models', function( $provide ) {
            $provide.value( 'Config', mockConfig );
        });
        module( 'ngLodash' );
        module( 'ui.router' );
        module( 'lens.document', function( $provide ) {
            $provide.value( 'Labels', mockLabels );
            $provide.value( 'PubSub', mockPubSub );
        });
    });

    beforeEach( inject( function ( _Document_global_, _Document_ ) {
        injectCoreServices();

        Document_global = _Document_global_;
        Document = _Document_;
    }));

     -------- 
 describe( 'Document Service() DocHistory', function () {
            it( 'Should send the client security check query to the server', function () {
                var bResult = false;
                $httpBackend.expectGET( DOC_HISTORY_URL + '?id=11111' ).respond( true );
                Document.getHistory( 11111 ).then( function ( response ) {
                    bResult = response;
                });
                $httpBackend.flush();
                expect( bResult ).to.be.true;
            });

        });
    });
})();

I run the test using grunt the command is Grunt test. ButI get the below error:

The endpoint URL of the web service it is trying to connect is CORRECT. Can anyone please tell me if i'm doing everything the correct way.
