mocha-phantomjs的安装与运用

[FunnyZ]

你好！我尝试使用npm install mocha-phantomjs --save-dev，之后便是：

npm WARN deprecated npmconf@0.0.24: this package has been reintegrated into npm and is now out of date with respect to npm
npm WARN deprecated node-uuid@1.4.7: use uuid module instead

是不是现在不用mocha-phantomjs进行headless browser测试了？刚学的小白，有很多不明白，请赐教。
