#-------------------------------------------------------------------------
# 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_test TESTNAME SCRIPT EXPECTED
# do_execsql_test TESTNAME SQL EXPECTED
# do_catchsql_test TESTNAME SQL EXPECTED
#
# Commands providing a lower level interface to the global test counters:
#
# 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?
# permutation
# presql
#
# Set the precision of FP arithmatic used by the interpreter. And
# 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
# very large database files.

# -tclprep TCL script to run to prepare test.
# -sqlprep SQL script to run to prepare test.
# -tclbody TCL script to run with IO error simulation.
# -sqlbody TCL script to run with IO error simulation.
# -exclude List of 'N' values not to test.
# -erc Use extended result codes
# -persist Make simulated I/O errors persistent
# -start Value of 'N' to begin with (default 1)
#
# -cksum Boolean. If true, test that the database does
# not change during the execution of the test case.
