25 # Organization of tests in this file:
26 #
27 # vtab1-1.*: Error conditions and other issues surrounding creation/connection
28 # of a virtual module.
29 # vtab1-2.*: Test sqlite3_declare_vtab() and the xConnect/xDisconnect methods.
30 # vtab1-3.*: Table scans and WHERE clauses.
31 # vtab1-4.*: Table scans and ORDER BY clauses.
32 # vtab1-5.*: Test queries that include joins. This brings the
33 # sqlite3_index_info.estimatedCost variable into play.
34 # vtab1-6.*: Test UPDATE/INSERT/DELETE on vtables.
35 # vtab1-7.*: Test sqlite3_last_insert_rowid().
36 #
37 # This file uses the "echo" module (see src/test8.c). Refer to comments
38 # in that file for the special behaviour of the Tcl $echo_module variable.

40 # TODO:
41 # * How to test the sqlite3_index_constraint_usage.omit field?
42 # * vtab1-5.*
