# Test case to verify that concurrent transactions with intersecting
# write set, the same not null unique key, do conflict.
#
# T1: WS={t1.a= 1}
#
# T2: WS={t1.a= 1}
#
# Outcome: T1 must abort, T2 must commit.
#
# Test:
# 0. The test requires two servers: M1 and M2.
# 1. With both members ONLINE. Create a table on M1.
# 2. Checking the negative case in which there is a conflict.
# 3. Checking the positive case in which there is no conflict:
# 4. Assert table consistency.
# 5. Primary key equivalent i.e. Unique key must be NOT NULL
# 6. Clean up.
