Having `afterEach(cleanup)` in the test setup file breaks exported `screen` module on Bun test
-
@testing-library/react
version:15.0.7
- Testing Framework and version:
Bun test v1.1.21
- DOM Environment:
@happy-dom/[email protected]
Relevant code or config:
test.setup.ts
import { GlobalRegistrator } from '@happy-dom/global-registrator';
import { cleanup } from '@testing-library/react';
import { expect, afterEach } from 'bun:test';
import * as matchers from '@testing-library/jest-dom/matchers';
GlobalRegistrator.register();
declare module 'bun:test' {
interface Matchers<T> extends matchers.TestingLibraryMatchers<any, void> {}
interface AsymmetricMatchers extends matchers.TestingLibraryMatchers<any, void> {}
}
expect.extend(matchers);
afterEach(cleanup);
Component.spec.tsx
import { act, render, screen } from '@testing-library/react';
import { TextAreaInput } from './TextAreaInput.component';
import { describe, it } from 'bun:test';
describe('TextAreaInput', () => {
it('Should show in the DOM', async () => {
const { getByRole } = await act(() => render(<TextAreaInput />));
// Works fine!
getByRole('textbox')
// throws an error
screen.getByRole('textbox');
// TypeError: For queries bound to document.body a global document has to be available... Learn more: https://testing-library.com/s/screen-global-error
});
});
What you did:
I'm just trying to test a component using the screen
exported by react testing library using Bun test.
What happened:
everything was smooth, until I tried to use the screen
exported from the react testing library it threw an error about "global document has to be available",
upon inspecting, removing afterEach(cleanup)
from the test setup file or writing afterEach(cleanup)
in each test file will make it works,
Reproduction:
just run bun test --preload test.setup.ts
Problem description:
using the screen
exported while having the cleanup code in the test setup will break the test
Suggested solution:
just use the returned screen from the render
function.
