+#
+# 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.
