# 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. |
