Question

我试图理解grunt-karma插件和茉莉花框架来编写首次业力测试。当我运行业力测试（咕噜测试）时，我看到初始化模块，范围的错误。我究竟做错了什么？谢谢你的帮助。

gruntfile.js

 karma: {
        unit: {
          configFile: 'karma.conf.js'
        }
      }

grunt.registerTask('test',['karma:unit']);

karma.conf.js

files: [
  'scripts/bower_components/angular/angular.js',
  'scripts/bower_components/angular-mocks/angular-mocks.js',
  'config/config.js',
  'scripts/app.js',
  'scripts/controllers/*.js',
  'test/unittest/personController.test.js'
],

app.js

var app = angular.module('myApp', ['services.config']);

personController.js

app.controller('personCtrl', ['$scope', function($scope) {
    $scope.firstName = "John";
    $scope.lastName = "Doe";
    $scope.fullName = function() {
        return $scope.firstName + " " + $scope.lastName;
    };
}]);

config.js（service.config）

'use strict';

angular.module('services.config', [])
  .constant('configuration', {
    getAllBooks: '@@getAllBooks'
});

personController.test.js

describe('Testing AngularJS SampleApp [app]', function (){

    //myApp will be loaded once instead of mentioning in every it() function 
    beforeEach(module('myApp'));

    describe('1.Testing SampleApp Controllers', function(){

        var scope;
        var ctrl;

        //loading controller once inside describe instead of every it() function
        beforeEach(inject(function($controller,$rootScope){
                scope = $rootScope.$new();
                ctrl = $controller('personCtrl',{$scope:scope});
            }));

        afterEach(function(){
            //clean-up code 
        });

        it('should initialize the scope', function(){
            expect(scope.firstName).toBeDefined('John');
            expect(scope.lastName).toBeDefined('Doe');
        });

    });
});

和

    TypeError: Cannot read property 'firstName' of undefined

问题：
1.从grunt file.js引用karma.con.js的最佳方法是什么？我在一些博客中读过，我们也可以覆盖grunt文件中的所有karma.conf.js属性，而不是引用文件？
2.在xxx.test.js文件中访问控制器范围的最佳方法是什么？

Answer 1

我能够解决问题，感谢estus指出问题，我应该意识到。

personController.test.js

beforeEach(module('services.config'));
beforeEach(module('myApp'));

我没有加载services.config中使用的myApp模块。然后我得到TypeError的错误：angular.element.cleanData不是一个函数。我必须确保angular和angular-mocks的版本相同。

带走了 1.在加载应用程序之前加载所有相关模块
2.添加angualr，angualr-mocks以及所有脚本文件的链接 3.确保安装兼容的角度和角度模拟版本
