banana-populator.js

test("After /bananas returns a json struct, banana-selector should be populated", function() {
	var fakeBananaJson = [{id:5, color:"yellow"},{id:2, color:"green"}]
	var fakeAjax = function( params ) {
		params.success( fakeBananaJson );
	}
	var populator = new tdd.BananaPopulator({
		ajax: fakeAjax
