Doesn't work with custom jsdom #100
Description
dom-testing-libraryversion: 3.5.1reactversion: 16.4.1nodeversion: 10.4.1npm(oryarn) version: yarn 1.7.0
Relevant code or config:
Usual installation,
"testEnvironment": "node",
as jest configuration, then something like following in tests:
import { getByText } from 'dom-testing-library'
it('Suggests cities to search by', async () => {
const container = createJSDOM(...)
getByText(container, 'foobar')
})What you did:
Tried to use dom-testing-library with node environment in Jest + creating own jsdom instance in a helper and passing it to dom-testing-library.
What happened:
● Test suite failed to run
ReferenceError: window is not defined
at Object.<anonymous> (node_modules/mutationobserver-shim/dist/mutationobserver.min.js:3:1)
at Object.<anonymous> (node_modules/dom-testing-library/dist/wait-for-element.js:8:1)
at Object.<anonymous> (node_modules/dom-testing-library/dist/index.js:32:23)
Reproduction:
As above, enable node jest environment and try to use dom-testing-library with some custom container
Suggested solution:
check if shim is loaded on given container and install it only then? generally something to support no global window object in jest environment
