angular.mock.inject方法的问题

Question

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 .

    minErr/<@C:/Users/userone/Documents/myAppPkg/myApp/WebApiRole/bower_components/angular/angular.js:63:12

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_;
    }));

can any one help me out with this . ?

Answer 1

You should update the "karma-chrome-launcher" and "karma-firefox-launcher" in node_module. This may be solve the issue.

If you think the issue because of then one can use function.

But I think your unit test script is not getting chance for loading and execution.So,this will not reason for above error.

Thanks.

Answer 2

I found out the solution for this problem. Turns out i have missed some dependencies in the karma.conf.js . When you missed dependencies , the $inject method does not get executed . What i did was , from the index.html , copied all the dependencies (from bower componants folder and node_modules folder) and put them in the karma.conf.js under files .

for example , i have copied all the file dependencies from index.html and put it under files
