Test for click event using Jasmine test suite
提问by Ancient
I am using jasmineto test my application and right now no button exists in my code
but i want to write a test in which i can check that whether a click event is fired or not.
You can simply think that i want to fire click event without button .
我正在jasmine用来测试我的应用程序，现在我的代码中不存在按钮，
但我想编写一个测试，在其中我可以检查是否触发了单击事件。
您可以简单地认为我想在没有按钮的情况下触发点击事件。
Here is what i did
这是我所做的
scenario('checking that click event is triggered or not', function () {
given('Sigin form is filled', function () {
});
when('signin button is clicked ', function () {
spyOn($, "click");
$.click();
});
then('Should click event is fired or not" ', function () {
expect($.click).toHaveBeenCalled();
});
});
Thanks in advance .
提前致谢 。

What I generally tend to do is create a stuband assign the event to the stub. Then trigger the click event and check if it was called
我通常倾向于做的是create a stub将事件分配给存根。然后触发点击事件并检查它是否被调用
describe('view interactions', function () {
beforeEach(function () {
this.clickEventStub = sinon.stub(this, 'clickEvent');
});
afterEach(function () {
this.clickEvent.restore();
});
describe('when item is clicked', function () {
it('event is fired', function () {
this.elem.trigger('click');
expect(this.clickEventStub).toHaveBeenCalled();
});
});
});
