■ 搭建karma测试环境
  → 创建app和test文件夹
  →npm install karma --save-dev
  →npm install karma-jasmine --save-dev
  →npm install karma-chrome-launcher --save-dev
  →karma init
  →不断回车,在What is the location of your source and test files?中填写:
  app/**/*.js
  test/**/*.js
  ■ 第一个测试
  → 在test下创建test.js文件
  describe("true", function(){
  it("Should be true", function(){
  expect(true).toBeTruthy();
  });
  });
  → karma start karma.confi.js
  ■ 安装Angular相关
  → npm install angular
  → npm install angular-mocks
  → npm install angular-resource
  → 在karma.confi.js中添加对Angular相关文件的依赖
  files: [
  'node_modules/angular/angular.js',
  'node_modules/angular-mocks/angular-mocks.js',
  'node_modules/angular-resource/angular-resource.js',
  'app/**/*.js',
  'test/**/*.js'
  ],
  → karma start karma.confi.js
