11 # This file implements regression tests for SQLite library. The

12 # focus of this file is testing the operation of the library in

13 # "PRAGMA journal_mode=WAL" mode.

14 #

15 # More specifically, this file contains regression tests for the

16 # sqlite3_wal_hook() mechanism, including the sqlite3_wal_autocheckpoint()

17 # and "PRAGMA wal_autocheckpoint" convenience interfaces.
