jQuery chain testing with sinonJS

If you want to test something like this:

$('.selector').siblings('.siblings').toggleClass('hidden');

You can easily try this:

// Fake jQuery methods
var jQueryMethods = { toggleClass: empty, siblings: empty };

// First the methods that can be chained
sinon.stub(jQueryMethods, 'toggleClass').returns(jQueryMethods);
sinon.stub(jQueryMethods, 'siblings').returns(jQueryMethods);

// Then all jQuery function
sinon.stub(window, '$').returns(jQueryMethods);

And now you have full test-ready faked jQuery methods!
