# This test validate that if we have two sessions and one set gtid_next to the
# next automatic gtid, if both session execute a transaction in parallel one
# of the transactions will rollback.
#
# Test:
# 0. Test requires two servers.
# 1. Establish another connection to server, to execute transactions in
#    parallel.
# 2. Create a table and set a manual gtid_next equal to next automatic gtid.
#    Start a transaction.
# 3. Using the other connection execute a transaction.
# 4. Connect to first session and commit pending transaction. Server will
#    rollback it due to already used gtid.
# 5. Clean up.
