# This test will update in parallel, in the same member, N transactions
# with N different clients.
#
# The success of this test is determined by its termination. Any failure
# in the parallelism of a transaction shall make some transactions be
# rollback.
#
# Test:
# 0. The test requires one server.
# 1. With member ONLINE, create 20 clients connections. Create initial data.
# 2. Update the same row on server 1 in parallel by all clients.
# 3. Assert that the row has the expected value, the total number of updates.
# 4. Disconnect clients connections.
# 5. Clean up.
