Allow proxying requests randomly about dyson HOT 3 CLOSED

I've opened a new issue to suggest a more general feature that would also cover this use case.

@pjacekm I'm curious to why you want to introduce randomness, that is unpredictability, in the behaviour of the mock layer. For testing, that you want systematic and interpretable, you need the mocks to be predictable and deterministic. Are you using dyson in the context of some kind of stress test maybe?

Regarding this issue, I must disagree on the idea to use an arbitrary score system to express probability rather than a 0-1 ratio that is the universal standard in this respect.

Why not override the render function, you can do any kind of custom stuff in there:

module.exports = {
    path: '/path',
    render: function(req, res) {
        if(Math.random() > .5) {
            res.status(500).send('Random error');
        } else {
            res.set('Content-Type', 'application/json');
            res.send(200).send(res.body);
        }
    },
    template: {}
};

or

var request = require('request');

module.exports = {
    path: '/path',
    render: function(req, res) {
        if(Math.random() > .5) {
            res.status(500).send('Random error');
        } else {
            req.pipe(request('http://real.org/path')).pipe(res);
        }
    },
    template: {}
};

Thank you for your comments and suggestions. I was able to meet with our team, and we agreed on the fact that randomness would introduce unpredictability, which is not good. Closing the issue.
