# Since in the new DD the column mysql.trigger.definer is defined as NOT NULL
# it is impossible to create a trigger with undefined definer value.
# Therefore, the following test doesn't make sense for new DD and it is disabled.
# This test wasn't removed just as reminder and to provide rationality
# why it doesn't make sense.

# Tests for WL#2818:
#   - Check that triggers created w/o DEFINER information work well:
#     - create the first trigger;
#     - manually remove definer information from corresponding TRG file;
#     - create the second trigger (the first trigger will be reloaded; check
#       that we receive a warning);
#     - check that the triggers loaded correctly;
