Integration tests

[PabloKowalczyk]

Hello, how to write integration tests for components? Some examples in the documentation would be very helpful.
Thanks :)

You can use something like jsdom

I'm trying to configure Mocha with Webpack, but something is failing when i do import Btn from 'App/components/btn';. IDK this is the Monkberry or Mocha error. Call stack:

 RUNTIME EXCEPTION  Exception occurred while loading your tests

Check if your loaders is on.

[PabloKowalczyk]

Seems they are, SCSS loader works as expected. Requiring plain JS also works, but if any file import *.monk template then it starts to fail.
My module config:

[ { test: /\.jsx?$/,
       exclude: /(node_modules|bower_components)/,
       use: [Array] },
     { test: /\.css$/, use: [Array] },
     { test: /\.(png|jpg|jpeg|gif|ico|svg|webp)$/,
       loader: 'file-loader',
       options: [Object] },
     { test: /\.(woff|woff2|ttf|eot|otf)$/,
       loader: 'file-loader',
       options: [Object] },
     { test: /\.s[ac]ss$/, use: [Array] },
     { test: /bootstrap\.native/,
       loader: 'bootstrap.native-loader',
       options: [Object] },
     { test: /\.monk$/, loader: 'monkberry-loader' } ] }

EDIT
After some investigation i found out where the problem is. In generated output file for test there is a line btn.prototype = Object.create(Monkberry.prototype);, for some reason Monkberry.prototype is undefined. As a side note, Webpack's target is node, not web.
I was trying to debug it with console.log(Monkberry); but the output { Compiler: [Function: Compiler] } tells me nothing. Hope this will help you to find problem.

Hey, any progress with this issue? Maybe repo with bug will be helpful?

[antonmedv]

Sorry, haven’t time for this repo now.
