如何使用jasmine AJAX来存根Ajax函数

Question

下面是我的代码：

function sendRequestData(url, urlParameters) {
if (url != null && urlParameters != null) {
    $.ajax({
        url : url,
        method : 'POST',
        headers : {
            'Accept' : 'application/json'
        },
        contentType : 'application/json',
        data : JSON.stringify(urlParameters),
        dataType : "json",
        success : function(data) {
            successCallBack(data)
        },
        error : function(data, status, errorThrown) {
            failCallBack(data, status, errorThrown)
        }
    });

我想要存根函数并检查响应。有没有什么我可以用jasmine-ajax插件来做的？

Answer 1

it("should receive a successful response", function() {
  spyOn($, "ajax").andCallFake(function(e) {
    e.success({});
  });
  spyOn(window, "successCallBack");
  spyOn(window, "failCallBack");

  sendRequestData('dummyURL', ['dummyParam1', 'dummyParam2']);
  expect(window.successCallBack).toHaveBeenCalled();  //Verifies this was called
  expect(window.failCallBack).not.toHaveBeenCalled();  //Verifies this was NOT called
});

如果失败，可以用e.error()替换callFake，并颠倒successCallBack和failCallBack的断言
