I'm trying to mock react-bootstrap <Modal> component with jest. Here's a simple component using it:
// mymodal.js
import React from 'react'
import {Modal, Button} from 'react-bootstrap'
const MyModal = ({ visible, hide, title, onOk }) =>
<Modal show={visible} onHide={hide}>
<div className='simple-modal'>
<Modal.Header closeButton>{title}</Modal.Header>
<Modal.Body>
<div>I'm body</div>
</Modal.Body>
<Modal.Footer>
<Button className='invert-primary' onClick={hide}>
Cancel
</Button>
<Button bsStyle='primary' onClick={onOk}>
Ok
</Button>
</Modal.Footer>
</div>
</Modal>
export default MyModal
And here's basic snapshot test for it:
// mymodal.test.js
import renderer from 'react-test-renderer'
import * as React from 'react'
import MyModal from './mymodal'
jest.mock('react-bootstrap', () => {
function Modal(props) {
return <div>{props.children}</div>
}
Modal.Header = 'Modal.Header'
Modal.Body = 'Modal.Body'
Modal.Footer = 'Modal.Footer'
return({
Modal: Modal,
Button: 'Button',
})
})
describe('MyModal component', () => {
test('should render a modal', () => {
const modal = renderer.create(<MyModal
visible={true}
hide={() => ''}
title='Title' />)
expect(modal.toJSON()).toMatchSnapshot()
})
})
And here's snapshot:
// Jest Snapshot v1
exports[`MyModal component should render a modal 1`] = `
<div>
<div
className="simple-modal"
>
<Modal.Header
closeButton={true}
>
Title
</Modal.Header>
<Modal.Body>
<div>
I'm body
</div>
</Modal.Body>
<Modal.Footer>
<Button
className="invert-primary"
onClick={[Function]}
>
Cancel
</Button>
<Button
bsStyle="primary"
onClick={undefined}
>
Ok
</Button>
</Modal.Footer>
</div>
</div>
`;
I'm quite happy with the snapshot result, but I'd like to get better output for the <Modal> component itself so that the snapshot would contain also component's name (currenlty <div>) and props (currently no props shown).
How should the mocking be done to achieve this?
