Setting up

Hey guys,

II'm trying to configure webpack using mocha tests for nodejs project with mocha loader, but can not understand manual that you have here,
Can somebody describe step by step how to configure it

Thx

Very surprising no docs have been added / issue responded...... and yet this module still works!

I found this SO answer that describes what to do: https://stackoverflow.com/questions/32385219/mocha-tests-dont-run-with-webpack-and-mocha-loader

[jasonswearingen]

actually, I'm wrong. This module does not work. it is broken

Specifically, this code seems to be for an old version of mocha, because it breaks everything: https://github.com/webpack-contrib/mocha-loader/blob/master/src/start.js

I actually figured out you don't actually need this mocha loader, at all.

webpack should delete this loader and just paste a snippet for getting mocha working

here is my working code, based on the SO answer I linked above

//test-main.js

//bootstrap mocha, as per: https://mochajs.org/#running-mocha-in-the-browser
require( "mocha" )
mocha.setup( "bdd" )


//load up all test files following general advice from: https://stackoverflow.com/questions/32385219/mocha-tests-dont-run-with-webpack-and-mocha-loader
{
	const foundTestsRequire = require.context( "..", true, /.*\.test\.js?$/ )
	//console.log( `keys found = ${ foundTestsRequire.keys().length }` )
	for ( const key of foundTestsRequire.keys() ) {
		console.log( key )
		foundTestsRequire( key )
	}
}

//run tests
mocha.run()
