【问题描述】：
我从编写单元测试开始我的冒险，所以请放纵一下。在我的应用程序中，我使用 jQuery、backbone.js 和 underscore.js 并用于测试 mocha.js 和 chai.js。我有问题，因为我不知道如何使用这个工具测试事件。 Fox 示例我有改变输入值的函数。它在更改复选框值后调用。

register.js 文件：
App.Views.Register = Backbone.View.extend({
events: {
'click input[name="terms"]' : 'changeTermsConfirmation',
'click [type=submit]': 'onSubmitForm'
},
initialize: function(options) {
this.$termsConfirmedAtHidden = this.$('input[name="terms_confirmed_at"]');
},
changeTermsConfirmation: function(e) {
if ($(e.currentTarget).is(":checked")) {
this.$termsConfirmedAtHidden.val(Math.floor(Date.now() / 1000));
} else {
this.$termsConfirmedAtHidden.val('');
}
},
onSubmitForm: function() {
if (!this.$el.find('input[name="terms"]').is(':checked')) {
analytics.track('auth_register_not_checked_terms');
}
}
});
register.spec.js 文件：
$(document).ready(function() {
describe('Register Form', function() {
App.registerView = new App.Views.Register();
describe('initialize() function', function() {
it('Should initialize this.$termsConfirmedAtHidden variable by HTML object', function () {
expect(App.registerView.$termsConfirmedAtHidden).to.be.a('object');
});
});
describe('changeTermsConfirmation() function', function() {
it('Should set value of $termsConfirmedAtHidden element', function () {
//how to test this function
});
});
});
});
我的问题是如何为“changeTermsConfirmation()”函数编写合理的单元测试。我会感谢其他人的笔记、使用提示。
