玩笑测试：TypeError: (0 , _rtb.disableAllAds) is not a function

Question

A few questions on StackOverflow are like this one, but the suggestions haven't fixed my particular problem. I don't use react, only pure JS and I'm not able to continue my testing bc of this. Any help is appreciated. I'm also still new to Jest testing. This is the actual error I get (I get it on the first function so the 2nd will prob throw the error too) What I don't get is it says it's not a function but it clearly is:

● Test suite failed to run

    TypeError: (0 , _rtb.disableAllAds) is not a function

       99 |
      100 | // check for noads and dhb to disable RTB and ads
    > 101 | export const disableAds = disableAllAds(qsc);
          |                           ^
      102 | export const disableHb = disableAllHb(qsc);

A look into my files: In my index file:

import {
  disableAllAds,
  disableAllHb,
} from "../src/rtb";

export const disableAds = disableAllAds(qsc);
export const disableHb = disableAllHb(qsc);

Then in rtb.js:

import {
  disableHb,
} from '../index';

export const disableAllAds = (qsc) => (qsc.noads === true || (typeof window !== 'undefined' && window.noads === 'true')) ? true : false;
export const disableAllHb = (qsc) => (qsc.dhb === true || (typeof window !== 'undefined' && window.disableHB === 'true')) ? true : false;

And my test file - tests/rtb.test.js:

import {
  disableAllAds, 
  disableAllHb, 
} from '../src/rtb';

I get this error even before I touch the test file if I have my Jest --watch on. I'm not sure why this is but I need help figuring this out so I can continue writing my tests.

Thanks a lot for the help!

Answer 1

I can not make sure but that seems like 'circular dependency' issue to me.

Are you importing rtb from index and index from rtb?
