# This test intends to prove that members can survive reset master commands.
# These commands end up causing the members to purge their relay logs even when
# the member has some provisioned data.
# This test has 3 phases:
#  1) Insert some data and sync both members
#  2) Reset both members, insert some data on member one
#     Provision member two and start replication
#     Check that all data from phase 1 disappeared and the members are in sync.
#  3) Restart group replication on member 2, testing that no data remains
#     from phase 1
#
# Test:
# 0. The test requires two servers: M1 and M2.
#
# Phase 1: Insert some data and sync both members.
# 1. Bootstrap start a group on M1 and insert some data. Start GR on M2.
#    Validate both members have the same GTID set.
#
# Phase 2: Reset the group and provision a server.
# 2. Stop GR and reset master on both members.
# 3. On M1, add some data and bootstrap start group replication.
# 4. On M2, fake the member being provisioned. Start group replication.
# 5. Test that the group works by adding some data.
# 6. Validate both members have the same data.
#
# Phase 3: Restart group replication on M3.
# 7. Stop and start GR on M2.
# 8. Add some data on M2.
# 9. Validate both members have the same data.
#
# 10. Clean up.
