Add unit tests

[matheuss]

We need some tests:

• Spectron should be used
• AVA should be used

https://github.com/electron/electron-api-demos/blob/master/tests/index.js is a pretty good Spectron example to start from.

I tried AVA for a bit but it was quite slow to start up every time because it's doing so much transpilation.

Thanks for the link @zeke – will be needed since I never used Spectron 😅

Yeah, AVA takes some time to start – but it's awesome 😌 cc @sindresorhus

@zeke That should only be the first run. We cache everything. Unless you're using babel-register, which circumvents our cache, but I don't see why babel-register would be used here. Node.js 6 also improved require time significantly, so should help. We're working on a promising solution: avajs/ava#1052.

@sindresorhus sweet! I will give AVA another go.

I would like to start working on this. Maybe I can start doing tests in chunks and make pull requests for them?

[matheuss]

Sounds amazing @hyalkaf 😄 You could write the first ones and then send a [WIP] PR and then just keep adding the others 😄

[fokusferit]

Any progress here ? 😄

Otherwise I would try to start on it. Is the decision on AVA now final or Spectron ?

[sindresorhus]

@fokusferit No progress. Feel free to take it on. AVA + Spectron. Example here: https://github.com/electron/spectron/blob/master/README.md#with-ava
