Can't do $httpBackend.passThrough() with unit tests/karma

[Ryan Zec]

I am running angular 1.1.4

So I have the following karma configuration file:

    basePath = '../htdocs';

    files = [

        JASMINE,

        JASMINE_ADAPTER,

        //bunch more includes, note I am using angular-mocks

    ];

    autoWatch = false;

    browsers = ['Chrome','Firefox','Safari'];

    singleRun = true;

and here is an example of a unit test file

    describe('Desktop Controller', function(){

        var scope, $controller, controllerOptions, $httpBackend, callback, unitTestMocker;

    

        beforeEach(module('of'));

        beforeEach(module('unitTestMocker'));

    

        beforeEach(inject(function($injector, $rootScope) {

            $httpBackend = $injector.get('$httpBackend');

            callback = jasmine.createSpy();

            scope = $rootScope.$new();

            $controller = $injector.get('$controller');

            unitTestMocker = $injector.get('unitTestMocker');

            controllerOptions = {

                $scope: scope

            };

    

            $httpBackend.when('GET', /\.html$/).passThrough();

        }));

    

        afterEach(function() {

            $httpBackend.verifyNoOutstandingExpectation();

            $httpBackend.verifyNoOutstandingRequest();

        });

    

        it('should have basic elements', function() {

            unitTestMocker.setValidLoadSessionResponse();

            var controller = new $controller('DesktopCtrl', controllerOptions);

            unitTestMocker.flush();

    

            //make sure the session data got loaded

            expect(scope.session.get('user').firstName).toEqual('Good');

            expect(scope.session.get('user').lastName).toEqual('User');

        });

    });

The issue is that I get the error passThrough() is not a method and that would only happen according to the angular source code if $browser does not get set.  I though that running the unit tests like I am (specifying the specific browsers) would get the $browser defined since I though the test were executed in actual browsers.  Should I not have access to passThrough() in unit tests with karma?
