express-mock-request

express-mock-request is a utility function to make it easy to write tests for Node.JS Express applications.
In fact, it was extracted from the Express test-suite here. I
wanted to use it in my own application and I so I extracted it into this module and removed the mocha specific testing code.

#### How to use:

First, install using npm:

npm install express-mock-request

Then require it in your test file like so:

``javascript
var request = require('express-mock-request');
`

Let's say you want to test this simple express app to make sure it returns the proper status, body, and headers:

`javascript
var express = require('express')
var app = module.exports = express();

app.get('/', function(req, res) {
res.send("ok", {'Content-Type': 'text/html'}, 200);
});

// Only start listening on 8080 when this file is run directly i.e.: node app.js
if(!module.parent) {
app.listen(8080);
}
`

You could write your test like so:

`javascript
var request = require('express-mock-request');
// require the express application, notice how we exported the express app using module.exports above
var app = require('../app');

// This example uses nodeunit
exports.testGet = function(test){
request(app).get('/').expect(function(response) {
// response is the response from hitting '/'
test.equal(response.body, "ok");
test.equal(response.statusCode, 200);
test.equal(response.headers['content-type'], "text/html");
test.done();
});
}
``

You can see more examples in the express test suite here.
