ntf [![Build Status](https://secure.travis-ci.org/shutterstock/ntf.png)](http://travis-ci.org/shutterstock/ntf)
===

ntf is a network testing framework written in [Node.js](http://nodejs.org/).

See [the ntf homepage](http://code.shutterstock.com/ntf/) for more details about
the ntf framework.

## Getting Started

Install ntf

npm install ntf
    npm install ntf -g

Create a file named `ntfjs.org.js`

var ntf = require('ntf')
      , test = ntf.http('http://ntfjs.org')

exports.homepage = test.get('/', function(test) {
      test.statusCode(200)
      test.body('ntf')
      test.done()
    })

Run the tests

ntf ntfjs.org.js
