! 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.
