11 # This file implements regression tests for SQLite library.
12 #
13 # The focus of the tests in this file are to verify that the
14 # underlying TEXT or BLOB representation of an sqlite3_value
15 # changes appropriately when APIs from the following set are
16 # called:
17 #
18 # sqlite3_value_text()
19 # sqlite3_value_text16()
20 # sqlite3_value_blob()
21 # sqlite3_value_bytes()
22 # sqlite3_value_bytes16()
