Karma Plugins

See the Karma Documentation for additional details on custom - in this case, preprocessor - plugin development.

Dependency Injection in Karma

Dependency Injection in Karma is handled by Node-DI, but that library is deprecated. See the author's readme notes in the repo. Just something to be aware of as this dependency may change in Karma in the future. And, it defines $inject, which is something on which this plugin relies.

Logger

Logger is another dependency of Karma. See log4js
