From c5e5b8415e9c91d132678dcfccde8df848ee70c8 Mon Sep 17 00:00:00 2001
From: Phil Sutter <psutter@redhat.com>
Date: Fri, 25 Nov 2016 11:38:02 +0100
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.
