node.js - Webstorm 10 + Karma + ES6 - Unit testing -

first let me start mentioning unit tests works using gulp.

i'm trying run unit tests via webstorm (v10) problem the karam.conf.js pointing compiled js files, , not original files... there way tell webstorm compile files first before runs tests?

here karam.conf.js: (please note pre-compiled files @ same location looks *.spec.js)

module.exports = function (config) {     'use strict';     config.set({          basepath: '',          frameworks: ['mocha'],          files: [             'bundledtests/test/**/*.spec.bundle.js'         ],          // reporters configuration          reporters: ['mocha'],          plugins: [           'karma-mocha-reporter',           'karma-mocha',           'karma-phantomjs-launcher',           'karma-chrome-launcher'         ],          //reporters: ['progress'],          port: 9876,         colors: true,         autowatch: true,         singlerun: false,         usepolling: true,         atomic_save: false,          // level of logging         // possible values: config.log_disable || config.log_error || config.log_warn || config.log_info || config.log_debug         loglevel: config.log_info,            browsers: ["chrome"] //'phantomjs',      }); }; 

any appreciated!

use karma-babel-preprocessor.

add preprocessors section karma.conf.js:

preprocessors: {   'src/**/*.js': ['babel'],   'test/**/*.js': ['babel'] }, 

mark paths need processed before running in tests.
