I'm new to Rust and am far less along than you are, as evidenced by this project. I noticed that in the few files I spot checked, there aren't many/any tests. Without any context or opinion, I'm curious whether unit and integration testing are hard for a project like this.

Good point. As you say Kerla lacks unit tests I focused on running a SSH server as soon as possible.

IMO, writing and running tests in the kernel space is pretty easy thanks to Rust’s flexible testing feature [1].
