Expected/desired behavior:

It should work 😄

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem along with a gist/jsbin of your webpack configuration.

Just updated webpack from 2.2.0-rc.3 to 2.2.0-rc.4 and this is happened. All source code is here: https://github.com/egoroof/browser-id3-writer

What is the expected behavior?

It should work 😄, but I already answered for it before, edit the template!

What is the motivation / use case for changing the behavior?

To get users happy.

p.s. webpack made a lot of refactoring in rc and also introduced breaking change, that's not sweet...

@egoroof - Update to Karma-Webpakc 2.0.1

Be sure to read the note on the breaking change :)

[egoroof]

It's fixed now, thanks!

@d3viant0ne Thanks for the lib Joshua,

I still got this error with my environment :

Webpack version:
3.6.0
karma-webpack version:
2.0.5
Karma version:
1.7.1
Please tell us about your environment:
Windows 8
Browser: [Chrome 55]

Which actually just because i miss registering karma-webpack as plugins on the karma configuration.
But according the readme, it's still miss the plugins section, If you desire, i will make a PR for that
