I am trying to run a simple jest and enzyme test against a react component and test throws: ReferenceError: React is not defined. I followed all simple tutorials on jest and react testing but all of them resulted in the same exception. I used npm test and result was the same as yarn test, React not defined. I am confused. Any help would be appreciated.
Checkbox.test.jsx: simple test
import { shallow } from 'enzyme';
import sinon from 'sinon';
import Checkbox from './Checkbox';
describe('<Checkbox />', () => {
it('should render three <Checkbox /> components', () => {
const wrapper = shallow(<Checkbox />);
expect(wrapper.prop('title')).toEqual('Events — Event Radar');
});
});
Console log
$ yarn test

Import React in your test and the error should disappear:
import React from 'react';
I tried removing this import in one of my tests and I got the same error you mentioned.
I hope this helps.

I am getting the error "TypeError: (0 , _firestore.getFirestore) is not a function" When trying to run a Jest integration test with my app's Login page. It seems that Jest is unable to recognise it as a function despite the rest of my Expo app being able to recognise it just fine.
I am wondering if this is because My firebase config file uses Web Version 9 as required by Expo and if there are any solutions or alternatives to this.
Thanks
import { initializeApp } from 'firebase/app';
import { getFirestore } from "firebase/firestore";
// Firebase API
const firebaseConfig = {
};
const app = initializeApp(firebaseConfig);
export const db = getFirestore(app);
I have tried import { firestore } from "firebase/firestore", import "firebase/firestore",
export const db+ app.firestore().
None of them works.

I am trying to upgrade react-router-dom v5 to v6.
I removed , change to .
Now when I create simple functional component, pass to my , it works.
<BrowserRouter>
<Routes>
<Route
path="/"
key="homepage"
component={<MyComponent />}
/>
</Routes>
</BrowserRouter>
but when I try my real routes I get a lot of errors similar this:

Somebody know what is wrong? I can't figure it out. Maybe react-router-dom need other version of some other package?
Thanks in advance
react-router-dom#6 is completely written in typescript, so you can remove "#types/react-router": "^5.1.14" and "#types/react-router-dom": "^5.3.3" from the project's dependencies as they are no longer necessary and may possibly mess with any linters and transpilers your project uses.
npm uninstall -S #types/react-router #types/react-router-dom
You've also a conflicting version of react-router installed and it should be removed. react-router-dom re-exports all of react-router for convenience.
npm uninstall -S react-router
The only other issue I see is in the code. The react-router-dom#6 Route component API changed significantly from v5; there is no longer any component, and render and children function props, all replaced by a single element prop taking a ReactNode value, a.k.a. JSX.
Example:
<BrowserRouter>
<Routes>
<Route
path="/"
key="homepage"
element={<MyComponent />}
/>
</Routes>
</BrowserRouter>
Unfortunately same problem after update my code and uninstall react-router library.
After 4 hours of debugging I find out problem is in import of files.
When I import file by this way:
index.tsx
import {profileAction} from './model';
// import {profileAction} from './model/action'; // when I change import to this it works
and model/index.tsx looks
export * from './action';
export * from './action-type';
export * from './api';
export * from './state';
export * from './sagas';
and model/action.ts looks:
export const profileAction = {...}
then I ever get error like this:
index.tsx:66 Uncaught TypeError: Object(...) is not a function
at Module.<anonymous> (index.tsx:66:1)
at ./src/app/profile/component/profile-gallery-filter-form/index.tsx (index.tsx:94:1)
at __webpack_require__ (bootstrap:856:1)
at fn (bootstrap:150:1)
i haven't a clue why my imports are broken. Since update react-router-dom all imports works fine.
I created a new React Native project and used Jest testing, it goes very well. But when I try it in an existing app it couldn't work, instead it gave me the following error.I suspect it is a configuration error that caused this problem:
Error
SyntaxError: Unexpected token 'export'

I had tried many accepted answers on StackOverflow and internet but no luck on solving this problem.These are some of the links I can remember of, there might be a little unrelated because I faced the same problem with other modules apart from #react-navigation:

Can anyone help me to identify my mistakes? Thanks a lot.
For some reason my ide is printing out 'Unexpected token <. Remember, adjacent JSX elements must be wrapped in an enclosing parent tag' for the following react code. I don't understand why it's printing that error since the component it's referring to is wrapped in an enclosing parent tag the <TableBody> tag specifically.
/* #flow */
import React from 'react'
import TableBody from '#material-ui/core/TableBody'
import Roster from './roster.jsx'
import type { MembersType } from '../../typeDefs/MembersType.js'
type RanksType = {
_id: string | number,
rankName: string,
members: Array<MembersType>
};
export default (props: {

<Roster <---specifically refering to this element

I had a very similar issue.
Firstly delete (rename) your .babelrc file which you use (remove where ever you set it).
If storybook can't find that file, then it will use its own settings. This worked for me to prove that it was that file that caused the issue.
If this is the same for you then create a new .babelrc file, and place it into the storybook folder. Storybook will now use this and your project can continue to use the existing one.
The tricky part is finding the config setting in you existing .babelrc file that is breaking storybook - for me it was the react-hot-load/babel, but you don't have that listed.
My file ended up with only #babel/plugin-proposal-class-properties and #babel/plugin-proposal-rest-spread for plugins.
I just want to use enzyme to test my react components.
Blow is my test code. Do nothing but only import some dependencies.
import React from 'react';
import { shallow } from 'enzyme';
import List from '../../../src/pages/index/components/List';
describe('List components test', () => {
});
When I exec command npm run test, the termial will call error message like this
I search this problem with google, I find similar problem in github, https://github.com/airbnb/enzyme/issues/47, but I have tried everything metion in this issue, it still error all the time( like setting external for webpack)
So, how can I solve this problem?
my dependencies's version is blow
