Question

我无法弄清楚为什么Jasmine声称没有监视我正在监视的函数，尤其是因为调用时它正在登录buildLinksObj而不是在删除.and.callThrough（）时调用感觉我之前写过很多类似的代码没有任何问题。我正在使用Jasmine 2.9

我收到的错误消息是：

1) addToLinks should call buildLinksObj if its given an object with children 
     it should add the personalized links to PageApp.meta.analytics.links
     Expected spy buildLinksObj to have been called.
    at UserContext.<anonymous> (http://localhost:9877webpack:///tests/specs/common/FetchPersonalContent.spec.js:854:0 <- tests/app-mcom.js:104553:48)

这是我的代码的例外：

FetchPersonalContent.js

const buildLinksObj = (responseObj = {}, targetObj, PageApp) => {
  console.log('it logs in buildLinksObj') // This is logging!
}

const addToLinks = (responseArr, personalizedLinks) => {
  responseArr.forEach((media) => {
    const type = media.type;
      const typeObj = media[type];
      buildLinksObj(typeObj, personalizedLinks, PageApp);
      if (typeObj && typeObj.children) {
        console.log('has children!')
        console.log('typeObj.children is: ', typeObj.children);
        typeObj.children.forEach((child) => {
          console.log('has a child')
          buildLinksObj(child, personalizedLinks, PageApp);
          console.log('buildLinksObj was definitely called. what the heck?')
        });
      }
    });
}

export {buildLinksObj, addToLinks, FetchPersonalContent as default,
};

FetchPersonalContent.spec.js

import * as FetchPersonalContent from '../../../src/FetchPersonalContent'; // my path is definitely correct

describe('it should add the personalized links to PageApp.meta.analytics.links', () => {
  it('addToLinks should call buildLinksObj if its given an object with children ', () => {
    spyOn(FetchPersonalContent, 'buildLinksObj').and.callThrough();
    FetchPersonalContent.addToLinks([{
    "personalId": 30718,
    "type": "carousel",
    "carousel": {}
  }], {});
    expect(FetchPersonalContent.buildLinksObj).toHaveBeenCalled();
  });
});

非常感谢您的帮助！

我感觉规范文件中的FetchPersonalContent.buildLinksObj与FetchPersonalContent.js文件中的buildLinksObj指向的实例不同。

为什么需要export {FetchPersonalContent as default}？我假设您在问题中共享了FetchPersonalContent.js的完整内容。

可能的解决方案：

您可以尝试从FetchPersonalContent语句中删除export。

或

代替

export {buildLinksObj, addToLinks, FetchPersonalContent as default,
};

您可以直接export文件中的常量FetchPersonalContent.js。
