Testing Zuora in production

idea-1.md

1. Make up a simple proxy server (see below).
2. We give that a DNS entry Eg, next-signup-test-suite.ft.com
3. Create a single Zuora configuaration, valid for that host.
4. The proxy server forms a URL from a ft-heroku-backend header sent by each test suite + path of the original request and proxies that request to the temporary Heroku backend.
5. As long as the proxy server does not cache any requests we should be able to spin up as many concurrent branches as we need.

var https			= require('https');
var app				= require('express');

app.get('/:path*', function(req, res) {
	var url = 'https://' + req.get('ft-heroku-backend') + '/' + req.path;
	https.get(url, function(proxyRes) {
		proxyRes.pipe(res);
	});
});
