For starters, I don't really know what multiple webpack configurations is for. I'm looking into it only because of #76.

I basically just added my webpack configuration twice to webpack: in karma.conf.js and running some tests fails immediately:

$ ./node_modules/.bin/karma start --single-run

webpack: bundle is now VALID.

I recently bumped into this issue as well Path is a file error loading tests with Karma and Webpack.

Closing this as there are resolutions in both the StackOverflow question and it's comment ( specific to the error above ) and the complex config in the example directory.
