# Tests to run: test' script, test' description, ...
# Test' script is in form
#
# script_name[.ntm][ T]
#
# script_name is name of file in ./sqls
# .ntm means that script will be used for some initialization
# and should not be timed: runtests.pl opens /dev/null as STDERR
# in this case and restore STDERR to result file after script done.
# Script shouldn't notice either he is running for test or for
# initialization purposes.
# T means that all queries in this test (initialization ?) are to be
# executed in SINGLE transaction. In this case global variable $XACTBLOCK
# is not empty string. Otherwise, each query in test is to be executed
# in own transaction ($XACTBLOCK is empty string). In accordance with
# $XACTBLOCK, script is to do DBMS specific preparation before execution
# of queries. (Look at example in sqls/inssimple for MySQL - it gives
# an idea of what can be done for features unsupported by an DBMS.)
