Description
Hi, I was trying to test the dialog component but it's not working.
Here is my component code
import Toast from '@/utils/Toast';
import PropTypes from 'prop-types';
import Dialog from 'rc-dialog';
import React from 'react';
import enhanceMessage from './enhanceMessage';
function ErrorDialog({ dismissError, error, breakoutFullText }) {
const { message, code, name } = error || {};
const enhancedMessage = enhanceMessage(message, code, breakoutFullText, name);
const styles = {
dialogContent: {
display: ' flex',
flexDirection: 'column',
justifyContent: 'center',
alignItems: 'center',
},
};
if (code === 53105) {
Toast.info(breakoutFullText);
return true;
}
return error !== null ? (
<Dialog
title="Error"
className="main-dialog"
style={{ height: 200, width: 400, top: '20%' }}
onClose={() => dismissError()}
visible={error !== null}
destroyOnClose
animation="zoom"
maskAnimation="fade"
footer={
<button type="button" className="btn button" key="close" onClick={dismissError}>
OK
</button>
}>
<div style={styles.dialogContent}>
<h3>{name === 'NotFoundError' ? 'No camera found' : enhancedMessage}</h3>
<div>
{code && code !== 53105 && (
<pre>
<code>
Error Code:
{code}
</code>
</pre>
)}
</div>
</div>
</Dialog>
) : null;
}
Here is my test code
import ErrorDialog from '@/components/TwilioVideoMeeting/ErrorDialog/ErrorDialog';
import { shallow } from 'enzyme';
import Dialog from 'rc-dialog';
import React from 'react';
describe('Testing the ErrorDialog component', () => {
const message = 'Fake Error message';
it('should display error message but not error code is the later does not exist', () => {
const error = { message };
const wrapper = shallow(<ErrorDialog dismissError={() => {}} error={error} />);
expect(wrapper.find(Dialog).text()).toContain(message);
expect(wrapper.find('code').exists()).toBe(false);
});
});
It throws following error
the ErrorDialog component › should display error message but not error code is the later does not exist
expect(received).toContain(expected) // indexOf
Expected substring: "Fake Error message"
Received string: "< />"
Any Help would be appreciated

Research direction
Start with the ErrorDialog component and its test at the paths shown in the issue, then inspect how the imported rc-dialog component is rendered by Enzyme shallow. Reproduce the reported text output and determine whether the test or component behavior is incorrect. Done means the test reliably observes the expected message and code absence, or the issue is clarified with the required project change.
