Complex example from README.md file is not passing with jest + jsdom

[spamshaker]

• @testing-library/react version: 10.4.3
• Testing Framework and version: Jest: 26.1.0
• DOM Environment: jest-environment-jsdom, jsdom:16.2.2

Relevant code or config:

https://github.com/testing-library/react-testing-library/blob/master/README.md#complex-example

What you did:

1. forked to https://github.com/spamshaker/dom-testing-library-template
2. added two files base on example README.md#complex-example
   here (spamshaker/dom-testing-library-template@1ee1ff0)
3. Got couple of errors which are fixed step by step in the pull request [react-testing-library] Fix for complex example running issue spamshaker/dom-testing-library-template#1

What happened:

Cannot run mentioned example with basic configuration + code contains some bugs which fails tests

Reproduction:

clone exact commit spamshaker/dom-testing-library-template@1ee1ff0
npm i
npm run test

Problem description:

This complex example is not passing in jest jsdom due to couple of issues

Suggested solution:

replace README.md#complex-example code by files from PR
https://github.com/spamshaker/dom-testing-library-template/pull/1/files
or include reference to repo that resolves those issues and allows to run and pass unit tests

I don't think the Babel config is needed, CRA's defaults for Jest should be fine. I'm also not sure issues there are with dom-testing-library-template vs react-testing-library. Could you please open separate PRs in both repos to address some of these issues (assuming there are issues with both) so we can have a more focused review?

I played with it a bit and it looks fine.
Locally RCA works great except from few errors which fixed by #806.

about the Code Sandbox, I guess this happens because the complex example uses msw/node so it won't work there.
https://codesandbox.io/s/dom-testing-library-template-forked-2se34?file=/src/__tests__/login.test.js
[MSW] Failed to execute `setupServer` in the environment that is not NodeJS (i.e. a browser). Consider using `setupWorker` instead.
for more details, as the error points to, take a look on mswjs/msw Browser section

@nickmccurdy, @spamshaker IMO we can close this one, the complex example in README was updated by @lidoravitan and the codesandbox with msw won't work since it needs NodeJS environment to run.. wdyt?

It seems like most issues here have either been solved or given suggested fixes. I'll close this but if @spamshaker still has issues feel free to reply.
