# BUG#20141
# The following tests ensure that if user-defined variables are used in SF/Triggers
# that they are replicated correctly. These tests should be run in both SBR and RBR
# modes.
# This test uses a procedure that inserts data values based on the value of a
# user-defined variable. It also has a trigger that inserts data based on the
# same variable. Successful test runs show that the @var is replicated
# properly and that the procedure and trigger insert the correct data on the
# slave.
#
# The test of stored procedure was included for completeness. Replication of stored
# procedures was not directly affected by BUG#20141.
