Have you tried my other suggestion; doing an actual debug session with an lldb-mi client (emacs/vim/vs code/eclipse)? Of that doesn't work, I'm afraid you may have to do some detective work here to figure out how to add test coverage for this code path. I ssume that you already tried to create a synthetic test that suspends a process and then queries the status through the MI interface?

To check my changes I need to get HandleProcessEventStateSuspended called, so could someone help me with a sequence of lldb-mi commands which will call HandleProcessEventStateSuspended.
