# This test evaluates that group replication can detect SQL thread failures of
# its applier channel.
#
# The test guide is:
# 0. A two member group with started plugins
# 1. Create a table t1 on server 1 and replicate
# Also insert a value in the table without logging to the binlog
# 2. Insert a value on server 2 that will clash with data on server1
# 3. Check that server1 applier fails and the plugin goes to error mode.
# 4. Remove the value, restart the plugin and do a cleanup
