# This test verifies that server reports warnings upon start for persisted group
# replication variables, if plugin is not loaded. Later post installation,
# variable_source is shown as PERSISTED.
#
# Test:
# 0. The test requires one server.
# 1. Persist configuration on server1. Uninstall group replication plugin.
# 2. Restart server1 without plugin-load, it must NOT bootstrap the group.
#    Verify proper warnings are generated.
# 3. Install plugin and verify that variable_source is shown as PERSISTED and
#    group is bootstrapped.
# 4. Restart server1 with plugin-load. Verify group is bootstrapped.
# 5. Clean up.
