How to run tests with sinon?

Hi, I am trying to run a test package and noticing that webpack still seems to bundle things in node_modules even though I am using the following karma/webpack config: https://gist.github.com/fb66622fa8284c76e6d9

An example test file:

'use strict';

var React = require('react/addons');
//var sinon = require('sinon');

React gets bundled, without issue even though I’d think that excludes would ignore it. The issue is when I uncomment the sinon test, I get several critical issues:

WARNING in ./~/sinon/lib/sinon.js
Critical dependencies:
39:25-32 require function is used in a way, in which dependencies cannot be statically extracted
 @ ./~/sinon/lib/sinon.js 39:25-32

WARNING in ./~/sinon/lib/sinon/behavior.js
Critical dependencies:
353:25-32 require function is used in a way, in which dependencies cannot be statically extracted
 @ ./~/sinon/lib/sinon/behavior.js 353:25-32

Am I just doing things wrong by expecting mocha tests to run like they would on the server?

@josmardias use karma-sinon or karma-sinon-chai

If you need your unique setup, you can simple require sinon within webpack, and use modules: noparse: [ /sinon\.js/ ] within your webpack config (that worked for me). Documentation for module.noParse

Thanks @ColCh I ended up doing that and its working great. Here’s an example if anyone wants to see it. https://github.com/bitwise/status
