+From c5e5b8415e9c91d132678dcfccde8df848ee70c8 Mon Sep 17 00:00:00 2001

+Subject: [PATCH] test: Implement self-test functionality
+
+This allows to run 'test' unattended by setting environment variable
+SELFTEST=on. Instead of printing the settings libkeepalive should have
+changed, it uses the input values still present in environment to assert
+them being set correctly.
