# This file implements regression tests for SQLite library.

# This file test deferred foreign key constraint processing to make
# sure that when a statement not within BEGIN...END fails a constraint,
# that statement doesn't hold the transaction open thus allowing
# a subsequent statement to fail a deferred constraint with impunity.
