Looks good, although I am not sure what defining the Controller class in tests does with autoloading.. I'll check it and get back to you.

We use it use in our project with a lot of dependencies and there is no problem with the autoloader. But rather, try it for sure.

@lookyman pull request was updated, added a fix. Service "" is not registered in the container.
