-# The focus of the tests in this file are to verify that the
-# underlying TEXT or BLOB representation of an sqlite3_value
-# changes appropriately when APIs from the following set are
-# called:
-#
-#     sqlite3_value_text()
-#     sqlite3_value_text16()
-#     sqlite3_value_blob()
-#     sqlite3_value_bytes()
-#     sqlite3_value_bytes16()
