Module not found in jest tests about auto-animate HOT 12 CLOSED

I fixed this via https://jestjs.io/docs/manual-mocks#mocking-node-modules
*Note my jest config includes roots: ["<rootDir>/jest"]

jest/__mocks__/@formkit/auto-animate/react.js

const useAutoAnimate = () => [null];
export { useAutoAnimate };

from auto-animate.

If you're not using the hook this fixed it for me after looking at

Insert the following under the file __mocks__/@formkit/auto-animate/index.ts

const autoAnimate = jest.fn((el: Element) => ({
  parent: el,
  enable: jest.fn(),
  disable: jest.fn(),
  isEnabled: jest.fn(),
}));

export default autoAnimate;

from auto-animate.

@Clm-Roig, forgot about that, it also requires mock of global.ResizeObserver in src/setupTests.ts:

// src/setupTests.ts

global.ResizeObserver = jest.fn().mockImplementation(() => ({
  observe: jest.fn(),
  unobserve: jest.fn(),
  disconnect: jest.fn(),
}))

from auto-animate.

I had the same issue, resolved via:

1. switch to autoAnimate with useRef instead of useAutoAnimate:

import {
  RefObject,
  useEffect,
} from "react"
import autoAnimate from "@formkit/auto-animate"

// https://github.com/formkit/auto-animate/issues/11
export const useAutoAnimate = (ref: RefObject<HTMLElement | null>) => {
  useEffect(() => {
    ref.current && autoAnimate(ref.current)
  }, [ref])
}

2. set/extend jest settings in package.json (source facebook/create-react-app#11946 (comment)):

"jest": {
  "transformIgnorePatterns": [
    "[/\\\\]node_modules[/\\\\](?!(@formkit/auto-animate)).+\\.(js|jsx|mjs|cjs|ts|tsx)$"
  ]
},

Step 2 should fix the new error from step 1:

export { autoAnimate as default, getTransitionSizes, vAutoAnimate };
    ^^^^^^

SyntaxError: Unexpected token 'export'

from auto-animate.

Oh yes I saw this solution when doing my research, but I hoped there will be something else more elegant... Anyway, thank you very much for your time, it works like a charm!

Yes, this is working, my question is more embracing, thinking about newcomers and how is the experience of you facing an error right away and don't have any docs about this error or "official" docs about how to integrate these two libraries.

Thanks for the hint @StK88 ! I tried what you suggested, with and without the "custom" useAutoAnimate hook but I got this error (in test environment only):

ReferenceError: ResizeObserver is not defined

from auto-animate.

Hi all, I tried all, the current solution is not working for me on TS, also not but using allowJs true, any idea?

from auto-animate.

I'm getting the same issue with Vue and Vitest.
ReferenceError: ResizeObserver is not defined

Adding this to the test file creates different issues:

 window.ResizeObserver = vi.fn().mockImplementation(() => ({
   observe: vi.fn(),
   unobserve: vi.fn(),
   disconnect: vi.fn(),
 }))
import { useAutoAnimate } from "@formkit/auto-animate/vue";
describe("testsuite", () => {...

Justin, can you give your opinion about this matter?

I questing this because I think Auto Animate it's an incredible library, and the "main marketing" slogan it's that a library that has "zero-config".

And not for me, but for a lot of devs, Jest is one of the most used js testing libraries, and because of that, I think that's an important issue to discuss.

If the library can't do anything about it, I think that's a good idea to have a disclaimer on the official page about how to integrate the library and what's configs need to use with Jest.

And if have anything to do to turn Auto Animate into a "zero config" with Jest, anyone is working on it or anyone can help?

@ArthurPedroti Does this not work for you? #29 (comment)

from auto-animate.

Honestly im not sure what we can do about this. ResizeObserver is increasingly part of the general web stack, but sadly it is not included in JSDom — jsdom/jsdom#3368. I don’t think we should mock resize observer ourselves.

Perhaps a note in the docs would be appropriate. Happy to accept a PR for that! In the meantime im closing this issue since it is related to module definitions which are unrelated and I believe have improved. 👍
