Current versions ^1.9.0 have testing issues out of the box: #130; however, I was able to work with version 1.6.1. But when testing 'Add Folder', I either cannot seem to get the form to submit, or it leads to an error which I think might be related to it submitting:
import React, {useState} from 'react';
import { render, screen, waitFor } from '@testing-library/react';
import userEvent from '@testing-library/user-event'
import FileBrowser from 'react-keyed-file-browser'
const filesInit = [
{
key: 'file1.txt',
size: 12288,
modified: new Date(),
url: 'https://localhost/file1.txt'
},
{
key: 'folder1/file2.txt',
size: 12288,
modified: new Date(),
url: 'https://localhost/folder1/file2.txt'
}
]
const mockOnCreateFolder = jest.fn()
const TestBrowser = ({ editable }) => {
const [files, setFiles] = useState(filesInit)
return (
<FileBrowser
files={files}
setFiles={setFiles}
onCreateFolder={mockOnCreateFolder}
/>
)
}

', async () => {
render(<TestBrowser />)
userEvent.click(screen.getByText(/Add Folder/i))
const nameInput = await screen.findByRole('textbox')
// Nothing seems to submit the form?!?
// 1) should submit from '{enter}'
userEvent.type(nameInput, '{selectall}Test Folder{enter}')
// 2) '{enter}' seperate
// userEvent.type(nameInput, '{enter}')
// 3) direct submit
// const form = nameInput.parentNode
// fireEvent.submit(form)
// 4) '{enter}' on the form
// const form = nameInput.parentNode
// userEvent.type(form, '{enter}')
// 5) create and click a submit button
// const form = nameInput.parentNode
// const submit = document.createElement('INPUT')
// submit.setAttribute('type', 'submit')
// form.appendChild(submit)
// userEvent.click(submit)
// doesn't get called or error :(
await waitFor(() => expect(mockOnCreateFolder).toHaveBeenCalled())
});
Scenarios 1-3 fail for not calling onCreateFolder, 4-5 are maybe submitting, but produce the following error

educated guess on the error: looks like it uses some refs when the name input is shown (new folder, rename) and seems there are issues with jsdom/jest/testing-library and refs being null...
