This doesn't always work. If you want to test integration of async components within a container, you need to be able to mock the async loading of them. We need better documentation here on how you do that. Simply flipping to sync require isn't really properly testing that scenario.

@andreyluiz why dont you use require('../components/Forgot')
in your tests instead of Forgot
. So you wont have this problem in your test env?

Managed to test by using the same server side rendering logic and cheerio to parse the output.
import React from 'react';
import asyncBootstrapper from 'react-async-bootstrapper';
import cheerio from 'cheerio';
import { AsyncComponentProvider, createAsyncContext } from 'react-async-component';
import { expect } from 'chai';
import { renderToStaticMarkup } from 'react-dom/server';
import Container from './index';
describe('Some Container', () => {
it('should resolve on the server', (done) => {
const asyncContext = createAsyncContext();
const component = (
<AsyncComponentProvider asyncContext={asyncContext}>
<Container />
</AsyncComponentProvider>
);
asyncBootstrapper(component)
.then(() => {
const html = renderToStaticMarkup(component);
const $ = cheerio.load(html);
expect($('div').children().length).to.equal(2);
// etc...
done();
})
.catch(error => {
done(error);
});
});
});

Kent C Dodds also has an integration test friendly library react-testing-library
. I would recommend looking at that one too 👍
