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.
