# This file implements regression tests for SQLite library. The
# focus of this file is testing the operation of the library in
# "PRAGMA journal_mode=WAL" mode.
#
# More specifically, this file contains regression tests for the
# sqlite3_wal_hook() mechanism, including the sqlite3_wal_autocheckpoint()
# and "PRAGMA wal_autocheckpoint" convenience interfaces.
