+# Some simple warm-body tests with a single database file in rollback 
+# mode:
+#
+#   quota-2.1.*: Test that SQLITE_FULL is returned if the database would
+#                exceed the configured quota.
+#
+#   quota-2.2.*: Test that SQLITE_FULL is not returned and the database
+#                grows if the callback extends the quota when the database
+#                attempts to grow beyond the configured quota.
+#
+#   quota-2.3.*: Open and close a db that is not part of any quota group. At
+#                one point this was causing mutex refs to be leaked.
+#
+#   quota-2.4.*: Try to shutdown the quota system before closing the db
+#                file. Check that this fails and the quota system still works
+#                afterwards. Then close the database and successfully shut
+#                down the quota system.
