# Check the layout of information_schema.triggers and the impact of
# CREATE/ALTER/DROP TABLE/VIEW/SCHEMA ... on it.
#
# Note:
#    This test is not intended
#    - to show information about the all time existing triggers
#      (there are no in the moment) within the databases information_schema
#      and mysql
#    - for checking storage engine properties
#      Therefore please do not alter $engine_type and $other_engine_type.
