Answer 1

I find the best way to deal with this is using a factory pattern. You can create a class say ServiceFactory and it has a single method create() it can accept an argument which is used to dynamically choose which concrete class to instantiate.

It has a case statement based on the argument.

It will use App::make(ServiceOne::class) or App::make(ServiceTwo::class).depending on which one is required.

You are then able to inject this into your controller (or service which depends on the factory).

You can then mock it in a service unit test.
