Package Exports

mocha-webpack/package.json

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (mocha-webpack) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

mocha-webpack

Precompiles your server-side webpack bundles before running mocha. Inspired by karma-webpack alternatives usage, but this is for NodeJS!

Looking for a test runner for the browser? Use karma-webpack instead.

Work in progress...

Features

easy testing of webpack code in node with mocha
reruns modified tests on file change

Usage

mocha-webpack --webpack-config webpack.config-test.js --watch --colors test_index.js

// webpack.config-test.js
var nodeExternals = require('webpack-node-externals');

module.exports = {
  target: 'node', // in order to ignore built-in modules like path, fs, etc.
  externals: [nodeExternals()], // in order to ignore all modules in node_modules folder
  devtool: "#source-map"
};

// test_index.js

// This gets replaced by webpack with the updated files on rebuild
var __webpackManifest__ = [];

// require all modules ending in ".test" from the
// src directory and all subdirectories
var testsContext = require.context("./src", true, /\.test$/);

function inManifest(path) {
  return __webpackManifest__.indexOf(path) >= 0;
}

var runnable = testsContext.keys().filter(inManifest);

// // Run all tests if we didn't find any changes
if (!runnable.length) {
  runnable = testsContext.keys();
}

runnable.forEach(testsContext);
