The path flow is the same as for the sample, the file just goes to
tools/testing/selftests rather than samples/.

Not much, really. I think the requirement is to exit with a non-zero
return code on failure, which you already do. 0 means success; 1 means
failure; 2 means skip, IIRC.

The main work in your case would be that the selftest needs to do its
checking and exit, so the stimuli must be triggered automatically.
(You can use a bash script to drive the events.)
