# Test case to verify that concurrent transactions with intersecting
# write set, on foreign key referencing not null unique key, do conflict.
#
# Test:
# 0. The test requires two servers: M1 and M2.
# 1. Create a table on server1.
# 2. Checking the negative case in which there is a conflict.
# 3. Checking the positive case in which there is no conflict.
# 4. Check the data sanity.
# 5. Clean up.
