# This test proves that the plugin will leave the group when it cannot enable
# the read mode in the server.
#
# Test:
#  0) The test requires two servers.
#  1) Bootstrap group with server 1.
#  2) Restart server 2 with start_on_boot=1 (to enable it for the install).
#  3) Insert some data on server 1.
#  4) Uninstall and Install the plugin on member 2 (auto start enabled on 2)
#     Use a debug point to make the read mode fail when connecting.
#  5) Verify that server 2 goes to ERROR state. Check that we cannot execute
#     transactions.
#  6) Check all is fine after restarting group replication on server 2.
#  7) Clean up.
