# This file implements regression tests for SQLite library. The
|
|
# focus of this file is generating semi-random strings of SQL
|
|
# (a.k.a. "fuzz") and sending it into the parser to try to
|
|
# generate errors.
|
|
#
|
|
# The tests in this file are really about testing fuzzily generated
|
|
# SQL parse-trees. The majority of the fuzzily generated SQL is
|
|
# valid as far as the parser is concerned.
|
|
#
|
|
# The most complicated trees are for SELECT statements.
