I'm using Mocha and Sinon to test that a click event listener has been added to a button on initialization. The click event is triggered on the button in the test but the spy isn't seeing it.
I can also attach a click event listener inside the test - the spy will catch this but the event is fired twice.
So I'm guessing it's a reference problem - accessing the correct reference to main.myMethod - and spy on that.
Anyone have any idea what I need to do to get this working?
var main = (function() {
function init() {
$("#btnGo").on('click', myMethod);
}
function myMethod() {
console.log("myMethod() was called");
return true;
}
init();
return {
init: init,
myMethod: myMethod
}
})();
if (typeof module !== "undefined" && module.exports !== null) {
module.exports = main;
}
/*Test*/
var expect = require("chai").expect;
var sinon = require('sinon');
var jsdom = require("jsdom");
global.document = jsdom.jsdom('<body></body>');
global.window = document.defaultView;
before(() => {
$ = require("jquery");
global.$ = $;
});
describe("Main.init()", function() {
it("should attach a click event listener to the button.", function() {
$("body").html("<button id='btnGo'>Go</button>");
var main = require("../src/main.js"),
spy = sinon.spy(main, "myMethod");
$('#btnGo').trigger("click");
sinon.assert.called(spy);
});
});
