I have been learn cpp for some months and started doing a project of making a chat server with a custom event loop using epoll for learning purposes.

But current i am not really sure on how to make these lower level code like interacting with os more testable and also on how to test it. I would like to have some tips/resources on this.

The trial and error method has been a bit frustrating 😅

Also ways to check and reduce unnecessary allocation would also be nice.
