2N/A# This file implements regression tests for SQLite library. The

2N/A# focus of this file is testing for correct handling of I/O errors

2N/A# such as writes failing because the disk is full.

2N/A#

2N/A# The tests in this file use special facilities that are only

2N/A# available in the SQLite test fixture.
