# The commands provided by the code in this file to help with creating
|
|
# test cases are as follows:
|
|
#
|
|
# Commands to manipulate the db and the file-system at a high level:
|
|
#
|
|
# copy_file FROM TO
|
|
# drop_all_table ?DB?
|
|
# forcedelete FILENAME
|
|
#
|
|
# Test the capability of the SQLite version built into the interpreter to
|
|
# determine if a specific test can be run:
|
|
#
|
|
# ifcapable EXPR
|
|
#
|
|
# Calulate checksums based on database contents:
|
|
#
|
|
# dbcksum DB DBNAME
|
|
# allcksum ?DB?
|
|
# cksum ?DB?
|
|
#
|
|
# Commands to execute/explain SQL statements:
|
|
#
|
|
# stepsql DB SQL
|
|
# execsql2 SQL
|
|
# explain_no_trace SQL
|
|
# explain SQL ?DB?
|
|
# catchsql SQL ?DB?
|
|
# execsql SQL ?DB?
|
|
#
|
|
# Commands to run test cases:
|
|
#
|
|
# do_ioerr_test TESTNAME ARGS...
|
|
# crashsql ARGS...
|
|
# integrity_check TESTNAME ?DB?
|

|
|
# do_execsql_test TESTNAME SQL EXPECTED
|

|
#
|
|
# set_test_counter COUNTER ?VALUE?
|
|
# omit_test TESTNAME REASON
|
|
# fail_test TESTNAME
|
|
# incr_ntest
|
|
#
|
|
# Command run at the end of each test file:
|
|
#
|
|
# finish_test
|
|
#
|
|
# Commands to help create test files that run with the "WAL" and other
|
|
# permutations (see file permutations.test):
|
|
#
|
|
# wal_is_wal_mode
|
|
# wal_set_journal_mode ?DB?

# wal_check_journal_mode TESTNAME?DB?

|
|
# configure SQLite to take database file locks on the page that begins
|
|
# 64KB into the database file instead of the one 1GB in. This means
|
|
# the code that handles that special case can be tested without creating
