  },

vue.config.js

const nodeExternals = require('webpack-node-externals')
const path = require('path')
let isCoverage = process.env.NODE_ENV === 'coverage';

module.exports = {
    mode: 'development',
    externals: [nodeExternals()],
    devtool: 'inline-cheap-module-source-map',
    output: {
        // use absolute paths in sourcemaps (important for debugging via IDE)
        devtoolModuleFilenameTemplate: '[absolute-resource-path]',
        devtoolFallbackModuleFilenameTemplate: '[absolute-resource-path]?[hash]'
    },

    module: {
        rules: [
            {
                test: /\.js$/,
                loader: 'babel-loader',
                exclude: /node_modules/
            }
        ].concat(
            isCoverage ? {
                test: /\.(js|ts)/,
                include: path.resolve('src'),
                loader: 'istanbul-instrumenter-loader',
                options: { esModules: true }
            }: [],
            {
                test: /.js$/,
                exclude: /(node_modules|bower_components)/,
                loader: 'babel-loader',
            },
            {
                test: /\.ts$/,
                exclude: /(node_modules|bower_components)/,
                loader: 'ts-loader'
            }
        )
    },
    target: 'node',
    externals: [nodeExternals()],
    devtool: "inline-cheap-module-source-map"
}

My test folder structure looks like this:

My test code looks like this:

So far i tried running these commands:

"test-ci": "mocha-webpack --webpack-config vue.config.js --require test/setup.js test/**/*.js"
"cover": "cross-env NODE_ENV=coverage nyc --reporter=lcov --reporter=text npm run test-ci"

If i ran test-ci it will output this: WEBPACK Compiled successfully in 631ms But is just a blank page after then if i ran cover then the output come out as nothing being log by nyc:

What am i doing wrong here, been trying to figure this out for several hours now!
