react-dom/test-utils Deprecation Warnings
ReactDOMTestUtils.act() warning
act
from react-dom/test-utils
has been deprecated in favor of act
from react
.
Before:
import {act} from 'react-dom/test-utils';
After:
import {act} from 'react';
Rest of ReactDOMTestUtils APIS
All APIs except act
have been removed.
The React Team recommends migrating your tests to @testing-library/react for a modern and well supported testing experience.
ReactDOMTestUtils.renderIntoDocument
renderIntoDocument
can be replaced with render
from @testing-library/react
.
Before:
import {renderIntoDocument} from 'react-dom/test-utils';
renderIntoDocument(<Component />);
After:
import {render} from '@testing-library/react';
render(<Component />);
ReactDOMTestUtils.Simulate
Simulate
can be replaced with fireEvent
from @testing-library/react
.
Before:
import {Simulate} from 'react-dom/test-utils';
const element = document.querySelector('button');
Simulate.click(element);
After:
import {fireEvent} from '@testing-library/react';
const element = document.querySelector('button');
fireEvent.click(element);
Be aware that fireEvent
dispatches an actual event on the element and doesn’t just synthetically call the event handler.
