Do we really need microservices in order to scale out an application horizontally?
yes, sometimes (maybe most of the time) people just copy solutions from big tech companies. but we can't blaim big tech companies for everything. I'm trying to understand maybe Actors also has some limitations and I don't just see it

in general yes, you are right. we can scale a monolith as well, but usually we say monolith and mean that all things happen in "memory" and in this case in order to scale a monolith you need to deploy a whole new instance of you monolith and additional environment. it is not really flexible as microservices.
but in another hard we have actors which can be designed (from project / source code point of view) as a monolith, but behavior as microservices. and you can easily scale just a peace of your app, not entire one

TDD: Mocking services
well... I'd defenetly suggest you to go with mocking framework.
Most of them are simple to understand and learn how to use it.
Additionally I think they force you to design your tests properly with good sections:
setup
action
assert
One really cool scenario I can see that if you have a logic when class A with method A has should call class B with method B, but calling method B will depend on some input params. And method B returns nothing (let's say it is a logger or something like this). And you need to write a test witch will check that that method B was called.
With mocking you can setup your test even for this scenario without creating a lot of new abstractions.
