# This test validates that no issue exists when a member auto joins an existing
# group during installation.
#
# To test this:
#   0) The test requires two servers: M1 and M2.
#   1) Bootstrap group replication on member 1.
#   2) Restart server 2 with start_on_boot=1 (to enable it for the install)
#      Stop group replication and reset the applier channel.
#   3) Insert some data on server 1 and stop the applier to block recovery on
#      server 2.
#   4) Uninstall and Install the plugin on member 2 (auto start enabled on 2)
#   5) Verify that no transaction can be executed while server 2 recovers.
#   6) Check all is fine after unblocking recovery.
#   7) Clean up.
