Enzyme: How do you use mount/jsdom without mocha?

Created on 15 Dec 2015 · 8Comments · Source: enzymejs/enzyme

Hi. I've loaded jsdom like this:

jsdom.env({
    html: '<html><body></body</html>',
    done: () => runTests()
});

And just to be through I tried const document = jsdom.env... and const window = jsdom.env ...

The runTests method had this statement: mount();

But ever time I run it, I get the following error: "It looks like you called mount() without a jsdom document being loaded. ' + 'Make sure to only use mount() inside of a `describeWithDOM(...)"

Your documentation says I don't need to use describeWithDOM if I'm not using mocha.

I consider Stack Overflow a good place to find help for something you want to do with the library which is not a shortcoming of the library itself, but your own knowledge.

To me this seems like a legit question to post as an issue, because the library is indeed tied to Mocha, which might be something that should be fixed or at least documented.

I figured it out. You can close this or leave it to help others. What I needed to do was load jsdom as a global object in my node test script:

import jsdom as 'jsdom';
const doc = jsdom.jsdom('<!doctype html><html><body></body></html>');
const win = doc.defaultView;
global.document = doc;
global.window = win;

It might be good to post these things on stack overflow as it's a first resource for most developers these days.

"the library is indeed tied to Mocha"

The documentation implies that you can use it without mocha. Which is what I do, so far without problems, except for not knowing how to get jsdom working. Now that I've done that, everything is going well.

@silvenon @mgeduld We agree this is a legitimate issue. We are working on a 2.0 release that will gut out all ties to mocha, and also include guides/documentation on getting enzyme up and running in every popular testing framework. I apologize for the issues thus far, but I'm glad you've gotten it up and running!

@mgeduld your jsdom hack worked 👌 for me, thanks!

Not sure why, but your code wasn't working for me.

My version:

import {JSDOM} from 'jsdom'
const dom = new JSDOM('<!doctype html><html><body></body></html>')
global.window = dom.window
global.document = dom.window.document
