JS测试框架Karma安装使用

1.安装NodeJS

可以在http://nodejs.org/download/ 下载，我下载的是windows版本。

 

2.安装karma

  新建一个目录如：E:\JavaScript\karma

  E:\JavaScript\karma>npm install karma --save-dev

  E:\JavaScript\karma>npm install karma-jasmine karma-chrome-launcher --save-dev   //安装chrome插件

 其它相关插件需要的话也可以安装，如：

 npm karma-firefox-launcher #firefox浏览器插件  
 npm karma-junit-reporter #junit 测试报告插件  
 npm karma-coverage #单元测试覆盖率插件  

  验证是否安装成功：

  E:\JavaScript\karma>karma start
  INFO [karma]: Karma v0.12.17 server started at http://localhost:9876/
  INFO [Chrome 36.0.1985 (Windows 7)]: Connected on socket McpCZbkxpU1Qg-mtrrdj wi
  th id manual-1692

  可以在本机访问URL： http://localhost:9876,页面显示如下：
