Ability to inject dependencies

[julianlconnor]

Is it possible to inject module dependencies into stitched files for client side testing purposes?

E.g.,
// bar.js

var foo = require('../foo');

module.exports = function() {
  return foo();
};

// bar.test.js

var bar = require('bar');

// I want to mock foo.
describe('bar', function() {
   it('calls foo', function() {
      // how would you go about doing this?
   });
});

My solution was to add a method onto window that would allow you to do this following:
// bar.stub.test.js

var mock = sinon.mock();
var bar = requireAndInject('bar', { '../foo', mock);

// I want to mock foo.
describe('bar', function() {
   it('calls foo', function() {
      mock.once();
      bar();
      mock.verify();
   });
});

I can submit a pull request if deemed helpful. This seems to be the only solution for browser testing rendr apps.
