################################################################################
# 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 for table creation.
#
# Table with only unique key.
# Table with NULL key.
# Table with Unique NULL key.
# Table with a normal key. (Not unique)
#
# 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.
#
# Test:
# 0. The test requires two servers: M1 and M2.
# 1. Setup group of two members. Bring both the members ONLINE.
# 2. On M1:
# - Create table t1 with only unique key.
# - Create table t2 with possible NULL value for the key.
# - Create table t3 with unique NULL key.
# - Sync it to the group.
# 3. Testing all the three tables that will fail with following DML operations:
# - Test the INSERT instruction. It must fail.
# - Test the UPDATE instruction. It must fail.
# - Test the DELETE instruction. It must fail.
# - Sync data to the group.
# 4. Stop GR on M1. Stop GR on M2.
# 5. Testing all the three tables again with following DML operations on M1:
# - Test the INSERT instruction. It must succeed.
# - Test the UPDATE instruction. It must succeed.
# - Test the DELETE instruction. It must succeed.
# 6. Clean up.
