Question

我试图使用jasmine / karma / phantomJS在我的角度应用中测试一个简单的服务。

茉莉花版：2.4.1 角度/角度模拟：1.5.7 幻影：2.1.1

QueryParameters.service.tests.js :( QueryParameters.service.js是app.service模块的一部分，实际上是工厂，而不是服务）

describe('myApp.QueryParametersService', function() {

  var QueryParametersService;

  beforeEach(module('myApp'));
  beforeEach(module('app.service'));
  beforeEach(inject(function ($injector) {
    QueryParametersService = $injector.get('QueryParametersService');
  }));

  var testObject = {
    name : 'Hans',
    age  : '27'
  };

  it('Should output correct querystrings', function() {
    expect(QueryParametersService.toQueryParams(testObject)).toBe('?name=Hans&age=27');
  });

});

QueryParametersService.js：

(function() {
  'use strict';

  angular.module('app.service')
    .factory('QueryParametersService', QueryParametersService);

  QueryParametersService.$inject = [];

  function QueryParametersService() {

    var service = {
      toQueryParams : toQueryParams
    };

    return service;

    function toQueryParams(queryObject) {
      <removed code here>
    }
  }
})();

在Gruntfile.js中：

karma: {
      unit: {
        options: {
          frameworks: ['jasmine'],
          singleRun: true,
          browsers: ['PhantomJS'],
          files: [
            '<%= yeoman.client %>/bower_components/angular/angular.js',
            '<%= yeoman.client %>/bower_components/angular-mocks/angular-mocks.js',
            '<%= yeoman.client %>/app/app.js',
            '<%= yeoman.client %>/app/filters/filter.module.js',
            '<%= yeoman.client %>/app/directives/directive.module.js',
            '<%= yeoman.client %>/app/services/service.module.js',
            '<%= yeoman.client %>/app/services/tests/*.js'
          ]
        }
      }
    }

我的主模块（在app.js中）声明如下：

  angular.module('myApp', [
    'angular-thumbnails',
    'angularUtils.directives.dirPagination',
    'app.directive',
    'app.filter',
    'app.service',
    'color.picker',
    'ngCookies',
    'ngFileUpload',
    'ngImgCrop',
    'ngMaterial',
    'ngMessages',
    'ngResource',
    'ngSanitize',
    'ui.router',
    'validation.match',
  ])

运行测试时得到的错误：

PhantomJS 2.1.1 (Mac OS X 0.0.0) myApp.QueryParametersService Should output correct querystrings FAILED
        /<filepath>/client/bower_components/angular/angular.js:4632:53

PhantomJS 2.1.1 (Mac OS X 0.0.0): Executed 1 of 1 (1 FAILED) ERROR (0.002 secs / 0.009 secs)

我在哪里错了？

正如@jchen86指出的那样，QueryParametersService.js并未包含在配置中（我认为当我包含整个服务模块时它会被包含在内）。通过更改gruntfile以包含服务文件夹中的所有js文件来解决此问题：

'<%= yeoman.client %>/app/services/*.js'

使用angular-mocks / jasmine进行测试服务 - TypeError：undefined不是对象
