# WL#10412: GR: notify listener services on relevant group events
#
# This test case checks that the correct notifications are
# triggered to the listeners registered in the service registry.
#
# For that it relies on a table that is updated by a listener
# through the SQL service API.
#
# This file covers the scenarios for regular bootstrap, join, leave, recovering.
#
# |------------+----+---------------------------------------------+------------+--------|
# | Tested | | Scenario\Where | | |

# |------------+----+---------------------------------------------+------------+--------|
#
# Legend:
# - QL - Quorum Lost event
# - VC - View Changed event
# - RC - Role Changed event
# - SC - State Changed event
#
# To test the cases above, the test sets up a group of
# 2 servers in multi-master mode and proceeds to testing
# the different scenarios. These are highlighted in the
# test file.
