Issue with angular.mock.inject method

I am using folloing jasmine test case

'use strict';

describe('companyService', function() {

    var $httpBackend, companyService;

    beforeEach(angular.mock.module('myApp'));

    beforeEach(angular.mock.inject(function(_$httpBackend_ ,  _companyService_) {
        $httpBackend = _$httpBackend_;
        companyService = _companyService_;
    }));

    it('should return a promise for getCompany function', function() {
       // expect(typeof companyService.getCompany('foobar').then).toBe('function');
    }); 

});

i am getting the following error . as you can see above . i am not doing anything inside it block .

I assume this issue comes because of the angular.mock.inject method i have been using . because the execution does not enter the following block

beforeEach(angular.mock.inject(function(_$httpBackend_ , _companyService_) {
        $httpBackend = _$httpBackend_;
        companyService = _companyService_;
    }));
