Motivation

We need a reliable way of testing that the OS installs and configures correctly. By using a virtual machine and installing the ktc custom iso, we can then run tests within the VM to assert it is configured correctly and behaving correctly.

This approach needs to be high fidelity and make it easy to write new tests.

Solution

Using Deno package @antman/sim-test makes simulation tests easy to write.

Running a VM using virt-install and connecting via virsh requires ensuring isatty returns true as both these programmes expect a tty. The easiest way to do this was to spawn a pseudo terminal using python.

Added testing utilities to make simplify developing additional tests in future. I think this is a good basis to start with that leaves plenty of room to improve things in future.
