Cleanup globals after tests about tests

[zackify]

I had noticed a few of these issues when I made #6. I don't see what problems would be caused with global variables, at least so far. The only things that are global is React, window, and document. So I'm a little unsure about what you want cleaned up after a test runs.

As for the canUseDom, I found it's the only way when using jsdom inside of the library because for some reason imports aren't always loaded in order (or something else weird is happening). This library is meant to run inside of node v4+ not in the browser.

Hope that helped answer some things. Btw, thank you so much for wanting to use this library :) It makes testing so much faster for me, and I would gladly add anything to it that would help you too!

Thanks for your quick reply!
You are right, the tests run in node 4.

However, I'm using axios to make http requests for example and I'd like to test requests made within my app in my test suite too.
So in the browser, axios is using XMLHttpRequest and in node, they use the http library.
If you look at their code, they test for presence of XMLHttpRequest, which jsdom puts in the global.

It's totally possible to work around this by unsetting specific globals for certain tests but it does not feel like the perfect solution intellectually.

I you want to have a look at the project I'm working on:

• The offensive line I want to get rid of in a perfect world
• Using legit-tests for beautiful tests ❤️

Thanks for the links to your tests I see what you mean. The only thing I'm confused on now is that in the test you're doing to make an http request you're not including legit tests but I'm guessing it was included in another test and the globals are still there? If so then I see the problem.

Also, I think you'll like what I just added #9 :)

Edit: that changeValues function looks really nice, you should send a PR with it as bundled middleware!

[zackify]

@geowarin can you specify what you need done? I'm going to close this in a few days if there's no reply

Hi @zackify !
I have no perfect solution for the moment.
Not being tied to a testing framework means that you have no hook to do proper cleaning.

Maybe you could optionally let the user do the jsdom init?

#9 is fantastic!
I'll push the changeValues middleware as soon as you review #19 😄

I've just seen #14. It seems that we are moving towards an optional jsdom init, then.

I'm thinking even though it's as easy as not including the dom.js file, I
might make this a different file "legit-tests/nodom" or something?
