#***********************************************************************
#
# Regression testing of FOR EACH ROW table triggers
#
# 1. Trigger execution order tests.
# These tests ensure that BEFORE and AFTER triggers are fired at the correct
# times relative to each other and the triggering statement.
#
# trigger2-1.1.*: ON UPDATE trigger execution model.
# trigger2-1.2.*: DELETE trigger execution model.
# trigger2-1.3.*: INSERT trigger execution model.
#
# 2. Trigger program execution tests.
# These tests ensure that trigger programs execute correctly (ie. that a
# trigger program can correctly execute INSERT, UPDATE, DELETE * SELECT
# statements, and combinations thereof).
#
# 3. Selective trigger execution
# This tests that conditional triggers (ie. UPDATE OF triggers and triggers
# with WHEN clauses) are fired only fired when they are supposed to be.
#
# trigger2-3.1: UPDATE OF triggers
# trigger2-3.2: WHEN clause
#
# 4. Cascaded trigger execution
# Tests that trigger-programs may cause other triggers to fire. Also that a
# trigger-program is never executed recursively.
#
# trigger2-4.1: Trivial cascading trigger
# trigger2-4.2: Trivial recursive trigger handling
#
# 5. Count changes behaviour.
# Verify that rows altered by triggers are not included in the return value
# of the "count changes" interface.
#
# 6. ON CONFLICT clause handling
# trigger2-6.1[a-f]: INSERT statements
# trigger2-6.2[a-f]: UPDATE statements
#
# 7. & 8. Triggers on views fire correctly.
