This really needs some attention as soon as we are done with the CVE's, keychord, and modal feature.

I think we need integration tests for the daemon. Given how much we interact with the system, I don't think unit tests would be really helpful.

Ideally, we would run our integration tests in a VM/container to ensure swhkd behaves as expected (e.g., grabs devices properly, does not miss events...). This might be tricky to implement, though.

Yep it seems tricky indeed, do you have any possible solutions in mind?

I have been using spread in another project. It does not seem easy to set up, but it is easy to use after the initial setup. I am not sure how compatible this would be with GitHub actions, though.

We could also very well develop our own ad-hoc scripts to set up VMs/containers and test from there. This may be rather costly to implement.

Cool! I'll take a look at spread.
