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：
