// Basic usage
var res = new MockRes();

// With callback for 'finish' event
var res = new MockRes(function() {

res.on('error', function(err) {

	// as is true for any stream.
});

// Read status code
res.statusCode; // 200 by default

// Read body as string

// Read body as parsed JSON
res._getJSON(); // { chicken: true }

// Pipe body somewhere
