# Tests for WL#2818:
#   - Check that triggers are executed under the authorization of the definer.
#   - Check DEFINER clause of CREATE TRIGGER statement;
#     - Check that SUPER privilege required to create a trigger with different
#       definer.
#     - Check that if the user specified as DEFINER does not exist, a warning
#       is emitted.
#     - Check that the definer of a trigger does not exist, the trigger will
#       not be activated.
#   - Check that SHOW TRIGGERS statement provides "Definer" column.
#   - Check that if trigger contains NEW/OLD variables, the definer must have
#     SELECT privilege on the subject table (aka BUG#15166/BUG#15196).
#
#  Let's also check that user name part of definer can contain '@' symbol (to
#  check that triggers are not affected by BUG#13310 "incorrect user parsing
#  by SP").
