I'm trying to write Jasmine tests and I need a review and some advice on spying on events and their behavior.// my example source code;(function () {  var app = {    exampleModuleName: {      navigateTo: function () { /* do something */ }    },    navigation: {      init: function () {        this.routeHandler = this.handleRouteTo.bind(this);        // bind all events        this.bind();      },      bind: function () {                    $(document).on('click', '.js-route-to', this.routeHandler);      },      teardown: function () {        $(document).off('click', this.routeHandler);      },      handleRouteTo: function (event) {        event.preventDefault();        this.routeTo($(event.currentTarget).data('target'));      },      routeTo: function (target) {        var module = app[target];        if (module && $.isFunction(module.navigateTo)) {            module.navigateTo();        }      },    }  };}());And that is my uncompleted spec file.// my test codedescribe('App Navigation', function () {  describe('initiation the navigation module', function() {    it ('spy on behavior', function () {        var spy = spyOn(app.navigation, 'init');        app.navigation.init();        expect(spy).toHaveBeenCalled();    });    // which tests are missing to be sure about well tested properties and methodes?   });  describe('test routeTo handler', function() {    var nav = app.navigation;    beforeEach(function () {        this.routeHandler = nav.handleRouteTo.bind(this);    });    it ('should be defined', function () {        expect(this.routeHandler).toBeDefined();    });    it ('click at a link', function () {        var node = $('<a href= class=js-route-to data-target=exampleModuleName>some text</a>');        expect(node.length).toBe(1);        spyOn(nav, 'handleRouteTo');        node.click();        // why is it failed?        expect(nav.handleRouteTo).toHaveBeenCalled();    });  });});Please take a look and let us talk about this example. I want to learn more about testing.
