I want to test the content of my material-ui datagrid but only the first 3 columns (out of 8) are rendered in the test. I can test the content of these 3 columns, no problem with that.
Everything renders correctly on a web browser.
My best guess is that's it due to the width and height of the rendered datagrid as these warnings say, but I haven't been able to find a solution in the docs.
Material-UI: useResizeContainer - The parent of the grid has an empty width.
You need to make sure the container has an intrinsic width.
The grid displays with a width of 0px.
You can find a solution in the docs:

It could also be due to the mount function : (According to the material-ui docs, you should use enzyme's mount function as argument for the createMount function, but I am using react 17 and the official enzyme adapter is not out yet. I tried with @wojtekmaj/enzyme-adapter-react-17 but it didn't change anything. I am currently using 'render' from @testing-library/react)
const mount = createMount({mount:render})
Here is a simpler version of my component :
import React from "react";
import { DataGrid } from '@material-ui/data-grid';
import Button from "@material-ui/core/Button";
const Gridtest = (props) => {
const columns = [
{field: 'id', headerName: 'ID', type: 'number',headerAlign: 'left', width: 130 },
{field: 'tenant_id', headerName: 'Tenant ID', type: 'number',headerAlign: 'left', width: 130 },
{field: 'user_reference', headerName: 'Customer user reference', type: 'string',headerAlign: 'left', width: 250 },
{field: 'provider_name', headerName: 'Provider name', type: 'string',headerAlign: 'left', width: 220 },
{field: 'provider_id', headerName: 'Provider ID', type: 'number',headerAlign: 'left', width: 130 },
{field: 'expiration_date', headerName: 'Expiration date', type: 'dateTime',headerAlign: 'left', width: 220 },
{field: 'last_start', headerName: 'Last start date', type: 'dateTime',headerAlign: 'left', width: 130 },
{field: 'Action',
headerName: 'Action',
headerAlign: 'left',
width: 100,
renderCell: (params) => {
return (
<div>
<Button variant="contained" size="small" color="primary" disableRipple
onClick={() => null}>
Details
</Button>
</div>
)
},
},
];
const rows = [
{
"id": "10190",
"tenant_id": "12201",
"user_reference": "Xuser_ref",
"provider_name": "Xprovider",
"provider_id": "122",
"expiration_date": "2020-04-07T17:36:40+02:00",
"last_start": "2020-07-06T17:36:40+02:00"
},
{
"id": "23541",
"tenant_id": "96542",
"user_reference": "Yuser_ref",
"provider_name": "Yprovider",
"provider_id": "856",
"expiration_date": "2010-07-07T17:36:40+02:00",
"last_start": "2010-09-06T17:36:40+02:00"
}]
return(
<main>
<div style={{ display: 'flex', height: '100%',width: '100%', flexGrow: 1 }}>
<DataGrid style={{height: '100%', width: '100%'}} autoHeight rows={rows} columns={columns} pageSize={5} checkboxSelection={false} hideFooterSelectedRowCount/>
</div>
</main>
)};
export default Gridtest;
The test file for my simpler component (the test succeeds) :
import {screen, render, act, findByTestId} from '@testing-library/react'
import React from 'react'
import '@testing-library/jest-dom/extend-expect'
import Gridtest from '../../src/Gridtest'
import { createMount } from '@material-ui/core/test-utils';
describe('grid test', () => {
const mount = createMount({mount:render})
test('grid render', async () => {
await act(async () => {
mount(
<Gridtest />
);
});
expect(await screen.findByRole('grid')).toBeInTheDocument()
expect(await screen.findAllByRole('columnheader')).toHaveLength(3)
screen.debug(await screen.findByRole('grid'))
})
})
screen.debug(await screen.findByRole('grid')) returns :
