# Organization of tests in this file:
#
# vtab1-1.*: Error conditions and other issues surrounding creation/connection
# of a virtual module.
# vtab1-2.*: Test sqlite3_declare_vtab() and the xConnect/xDisconnect methods.
# vtab1-3.*: Table scans and WHERE clauses.
# vtab1-4.*: Table scans and ORDER BY clauses.
# vtab1-5.*: Test queries that include joins. This brings the
# sqlite3_index_info.estimatedCost variable into play.
# vtab1-6.*: Test UPDATE/INSERT/DELETE on vtables.
# vtab1-7.*: Test sqlite3_last_insert_rowid().
#
# This file uses the "echo" module (see src/test8.c). Refer to comments
# in that file for the special behaviour of the Tcl $echo_module variable.
#
# TODO:
# * How to test the sqlite3_index_constraint_usage.omit field?
# * vtab1-5.*
#
# vtab1-14.*: Test 'IN' constraints - i.e. "SELECT * FROM t1 WHERE id IN(...)"
#
# vtab1-18.*: Check that the LIKE optimization is not applied when the lhs
# is a virtual table column.
#
