# The intent of this test is to verify if the validations that were
# created within the Group Replication plugin in the runtime process
# are fully functional.
#
# It will test the invalid scenarios:
# - Table with no primary key
# - Table without InnoDB storage engine
# - Table without both
# - Table with 'CASCADE' referential key
# - Table with 'SET NULL' referential key
#
# It will cycle all cases in which the runtime validation is verified.
#
# Afterwards the plugin will be stopped and one of the cases will be tested in
# order to assess that the verification is no longer accomplished.
#
# One will test in a valid table that dynamic variables that can change in
# runtime will also cause a failure in validation if they have incorrect values.
#
# Table t4 in the test case was added because of BUG#21909427 DMLS ON
# BLACKHOLE TABLES ARE ALLOWED IN GR, as BLACKHOLE storage engine tables are
# considered to be transactional.

# Tables t5, t6, t7 and t8 in the test case were added because of
# BUG#21918361 GR CAN GENERATE INCONSISTENCIES IF THERE ARE MULTIPLE FK
# DEPENDENCIES. The decision is to block DML updates if the table contains
# foreign key with 'CASCADE' clause.
#
# Test:
# 0. The test requires one server.
#
# 1. With member being ONLINE.
#  - Create table without primary key.
#  - Create table with non-transactional(MyISAM) engine.
#  - Create table without primary key and with non-transactional(MyISAM) engine.
#  - Create table without InnoDB storage engine.
#  - Create auxiliary table with primary key and with InnoDB engine.
#  - Create table with 'ON UPDATE CASCADE' foreign key.
#  - Create table with 'ON DELETE CASCADE' foreign key.
#  - Create table with 'ON DELETE SET NULL' foreign key.
#  - Create table with 'ON UPDATE SET NULL' foreign key.
#
# 2. Testing all tables that will fail with following DMLs:
#    INSERT,  UPDATE,  INSERT...SELECT,  DELETE,  LOAD DATA,  REPLACE,
#    REPLACE...SELECT,  DELETE_MULTI,  UPDATE_MULTI
#
# 3. Test global variables that might change in runtime and which values are
#    not allowed in GR. Following settings are tested with DML operation on
#    auxiliary table:
#    binlog_checksum=CRC32,  binlog_format=STATEMENT,
#    transaction_write_set_extraction=OFF
#
# 4. Stop GR on member. Now, check following must succeed or fail with other
#    errors that not related to GR:
#    INSERT,  UPDATE,  INSERT...SELECT,  DELETE,  LOAD DATA,  REPLACE,
#    REPLACE...SELECT,  DELETE_MULTI,  UPDATE_MULTI
#
# 5. Clean up.
