After upgrading our project from karma v0.13.22 to v.1.0.0 we get following error:
You need to include some adapter that implements __karma__.start method!

Here is a the repo: https://github.com/SerkanSipahi/app-decorators

Reproducing error:

git clone https://github.com/SerkanSipahi/app-decorators.git
cd app-decorators
// change in package.json karma to 1.0.0
make install
make compile
make test

Anyone have an idea What causes this error ?
