event.preventdefault和茉莉花

Question

我有一个带有单击侦听器的对象，然后尝试为其编写测试。我使用Jasmine expect(event).toHaveBeenTriggered()有问题，看来问题是e.preventDefault语句。

听众：

$(document).on("click", "input", function (e) {
    e.preventDefault();
    // do something
});

测试：

describe("SomeTest", function () {
    "use strict";
    beforeEach(function () {
        setFixtures("<input />");
    });
    it("should have been triggered", function () {
        var input = $('input');
        var spyEvent = spyOnEvent(input, 'click' );
        $( input ).click();
        expect( spyEvent ).toHaveBeenTriggered();
    });
});

有没有办法让toHaveBeenTriggered工作或禁用preventDefault进行测试？

toHaveBeenPreventedOn()和CC_7和toHaveBeenPrevented()

中有特殊的Matcher s

来自文档：

var spyEvent = spyOnEvent('#some_element', 'click')
$('#some_element').click(function (event){event.preventDefault();})
$('#some_element').click()
expect('click').toHaveBeenPreventedOn('#some_element')
expect(spyEvent).toHaveBeenPrevented()
