+# 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").
