Within a test case, many system variables can be set by using statements such as these:
SET sql_warnings=1; SET sql_mode='NO_AUTO_VALUE_ON_ZERO';
But sometimes you need to restart the server to use command-line
options that are specific to a given test case. You can specify
these options in a file named
When a file named
exists, mysql-test-run.pl examines it for extra
options that the server needs to be run with when executing the
test_name test case. If no server has
yet been started or the current server is running with different
options, mysql-test-run.pl restarts the server
with the new options.
As a special case, the option
will be interpreted by mysql-test-run.pl, which
will then block the server from producing any core files or crash
dumps during this test. This may be useful for tests that
intentionally crash the server.
Another special case is
which can be used to set a different, longer timeout for a
particular test case. The given timeout in minutes will be used
for this test if it's longer than the default. This option was
added in MySQL 5.1.52.
Files in the
mysql-test/t directory with
names ending in
-slave.opt are similar, but
they are used for slave servers in replication tests.
Sometimes it's also necessary to execute some external commands
before starting the server, such as creating a directory. If you
add a file named
it will be executed by mysql-test-run.pl before
it starts the server; a similar file may be created for the slave
in replication tests.
.sh file is executed through
/bin/sh, it cannot be used on Windows, and any
tests using such a file will automatically be skipped if you run
on Windows. For this reason, this mechanism may be replaced with a
more portable one in some future release of MySQL.
