Error: You need to include some adapter that implements __karma__.start method!

[kmarecki]

I've upgraded karma from 0.13.22 to 1.1.1 and my tests don't work anymore.

I've looked which files are being loaded during startup and it seems that karma-systemjs/lib/adapter.js is missing in the newer version of Karma.

I've got similar result, but only when systemjs.includeFiles option is present.
On '0.13.22' is ok.

Seems to work fine for karma '1.1.2'.

I got this error when karma did not find any files and when using includeFiles .
I tried to load 'jspm_packages/npm/angular2@2.0.0-beta.17/bundles/angular2-polyfills.js' in includeFiles, but that didn’t work. Adding it as inline script in karmas regular files array fixed it for me.
