seems like a line delete slipped here above

while it is good to check for known error conditions, this one seems
very specific and could mutate easily. I.e. if the pidfile has a
different PID, the error message will not be the same as the one you
describe. This is better checked via a search expression.

You're checking the expected message first, that makes this second
check below for the unexpected message to be highly unlikely to happen
at this point.
I believe that checking just for the expected message would account for
the objective of the test.
