Test with jest

[InsideGH]

Hi all,

My testcases with an open Modal breaks when I step up react-semantic from version v.0.81.3 -> v.0.82.0.

The test case:

import React from 'react'
import renderer from 'react-test-renderer'
import Success from 'app/Success'

const showProps = {
show: true,
onClose: () => {}
}

test('renders open', () => {
const component = renderer.create(<Success {...showProps}/>)
let tree = component.toJSON()
expect(tree).toMatchSnapshot()
})

The error message (from inside react-test-renderer):
TypeError: parentInstance.children.indexOf is not a function

Any tips on how to get around this or fix it is much appreciated.

Thanks Peter.

In 0.82.0 we begin to use React.createPortal API. The described issue known and comes from react-test-render:

reactjs/react-modal#553
mui/material-ui#9243
facebook/react#11565

As I see resolution was merged facebook/react#12895 and will be shipped with [email protected] ✌️ You can check 16.4.3-alpha.0, however I don't recomend to use it in production.

The best is wait for issue resolution I think. We have similar issue in docs, #3020 😭
