# 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:
#
# is_relative_file
# test_pwd
# get_pwd
# copy_file FROM TO
# delete_file FILENAME
# drop_all_tables ?DB?
# drop_all_indexes ?DB?
# forcecopy FROM TO
# forcedelete FILENAME
#
# Test the capability of the SQLite version built into the interpreter to
# determine if a specific test can be run:
#
# capable EXPR
# ifcapable EXPR
#
# Calulate checksums based on database contents:
#
# dbcksum DB DBNAME
# allcksum ?DB?
# cksum ?DB?
#
# Commands to execute/explain SQL statements:
#
# memdbsql SQL
# 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?
# verify_ex_errcode TESTNAME EXPECTED ?DB?
# do_test TESTNAME SCRIPT EXPECTED
# do_execsql_test TESTNAME SQL EXPECTED
# do_catchsql_test TESTNAME SQL EXPECTED
# do_timed_execsql_test TESTNAME SQL EXPECTED
#
# Commands providing a lower level interface to the global test counters:
#
# set_test_counter COUNTER ?VALUE?
# omit_test TESTNAME REASON ?APPEND?
# 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?
# permutation
# presql
#
# Command to test whether or not --verbose=1 was specified on the command
# line (returns 0 for not-verbose, 1 for verbose and 2 for "verbose in the
# output file only").
