unfortunately you have to define on your own if you run it on node environment
Can someone provide more information about this? I made a stack overflow question about the same issue: https://stackoverflow.com/questions/45684811/jest-referenceerror-is-not-defined

I get this same error when I run jest test:
it('renders without crashing', () => {
const div = document.createElement('div');
ReactDOM.render(<App />, div);
});
Someone suggested this, but didn't work for me
const WebSocket = require('ws')
global.WebSocket= WebSocket
it('renders without crashing', () => {
const div = document.createElement('div');
ReactDOM.render(<App />, div);
});
As far as the undefined websocket issue goes: you should define your own websocket in the class constructor like this:
const asteroid = require('asteroid');
const WebSocket = require('ws');
const Connection = asteroid.createClass()
const portal = new Connection({
endpoint: 'ws://localhost:3000/websocket',
SocketConstructor: WebSocket // <-------------- HERE
})
I have also commented this on the stack overflow issue: https://stackoverflow.com/a/45697156/6573438
@holmrenser what fixed it for me was actually installing your PR: https://github.com/mondora/asteroid/pull/122
The changes to SocketConstructor weren't necessary for me.
ReferenceError: WebSocket is not defined
at Asteroid.init (node_modules/asteroid/lib/base-mixins/ddp.js:46:67)
which is caused by (I think) trying to access the global.WebSocket which Jest doesn't have
Your PR declares it, removing the need to search for it in the global
PS @holmrenser would you like to update your answer on SO and I'll approve it?
When trying to create a new connection the following error pops up:
