sqlite/test/tester.tcl
drh 4987c5c3c2 Testrunner.tcl enhancements: (1) Attempt to build the SQLite tcl extension 
if it is not already available.  (2) testrunner target "devtest" is added as
an alias for "mdevtest".  (3) Try to keep summary information at the end of
a test below 80-characters per line.  (4) Update the Makefile.in so that
the "clean" target removes the tcl extension built by item 1 above.

# 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").
