From 4cdabcddc5bd5b469c55090c9e51f4e1bf386d75 Mon Sep 17 00:00:00 2001 From: Paul Elder Date: Sat, 13 Jul 2019 04:29:12 +0900 Subject: test: logging: add logging process test Add a test to test that logging works in isolated child processes. Only logSetFile is tested, because stdout and stderr are closed for isolated child processes, and syslog and the none logging destinations are expected to be the same as non-isolated processes.
