14 # This file implements regression tests for SQLite library. The
15 # focus of this script is btree database backend
17 # In particular, this file tests a small part of the Delete logic
18 # for the BTree backend. When a row is deleted from a table, the
19 # cursor is suppose to be left pointing at either the previous or
20 # next entry in that table. If the cursor is left pointing at the
21 # next entry, then the next Next operation is ignored. So the
22 # sequence of operations (Delete, Next) should always leave the
23 # cursor pointing at the first entry past the one that was deleted.
24 # This test is designed to verify that behavior.
