# Multi Master recovery test
# This test focus on the recovery feature of multi master groups.
# The basic functioning of this test consists in loading some data to a group
# and then verify if a new joining member contains also this data after recovery.
# Three specific scenarios are tested:
#   1) A brand new member joins the group and recovers
#   2) The donor on 1) leaves and returns being now a joiner.
#   3) The joiner in 1) leaves and returns, doing a second round of recovery.
#
# Test:
# 0. The test requires three servers: M1, M2 and M3.
# 1. Test the recovery of new members:
#  - Bootstrap start GR on M1. Add some data for recovery.
#  - Start GR on M2 and M3. Check after recovery all members must see each other
#  - Validate data is present on all the members.
#  - Test group responds to requests well.
#  - All members must have the same GTID set.
#  - Check if the data is the same on joiner(M2) and donor(M1).
# 2. Test recovery on a member that left and now returns:
#  - Stop GR on M1, who never went through recovery.
#  - Add some data on M2 for recovery.
#  - Start GR on M1. Validate data.
#  - Test group responds to requests well. Sync group.
#  - Check if the data is the same on M1 and M2.
# 3. Testing a second recovery round on a member:
#  - Stop GR on M2.
#  - Add some data on M1 for recovery.
#  - Start GR on M2. Validate data.
#  - Test group responds to requests well.
#  - Check if the data is the same on M1 and M2.
# 4. Clean up.
