High-level testing for onion service configuration parsing
As a followup to #699 (closed), I want to implement tests for our configuration formats like those in arti::cfg.rs
.
There is a wrinkle here that onion services themselves do not exist by default, so the default configuration is just "", so I'm not sure the right way for us to test them via our existing mechanisms.
@Diziet, please let me know how you think I should approach this. That is, what tests do you think I should write, and about what parts of the code should I tweak?
