DESCRIPTION         top

       The Perl script performs stress-testing of

           than or equal to N was encountered. Set to 1 to abort on any

       •   --check-tests-file

           Periodically check the file that lists the tests to be run.
           If it has been modified, reread the file. This can be useful
           if you update the list of tests to be run during a stress

       •   --cleanup

           Force cleanup of the working directory.

       •   --log-error-details

           Log error details in the global error log file.

       •   --loop-count=N

           In sequential test mode, the number of loops to execute
           before exiting.

       •   --mysqltest=path

           The path name to the mysqltest program.

       •   --server-database=db_name

           The database to use for the tests. The default is test.

       •   --server-host=host_name

           The host name of the local host to use for making a TCP/IP
           connection to the local server. By default, the connection is
           made to localhost using a Unix socket file.

       •   --server-logs-dir=path

           This option is required.  path is the directory where all
           client session logs will be stored. Usually this is the
           shared directory that is associated with the server used for

           The default is 3306.

       •   --server-socket=file_name

           For connections to localhost, the Unix socket file to use,

       •   --sleep-time=N

           The delay in seconds between test executions.

       •   --stress-basedir=path

           This option is required.  path is the working directory for
           the test run. It is used as the temporary location for result
           tracking during testing.

       •   --stress-datadir=path

           The directory of data files to be used during testing. The
           default location is the data directory under the location
           given by the --stress-suite-basedir option.

       •   --stress-init-file[=path]

           file_name is the location of the file that contains the list
           of tests to be run once to initialize the database for the
           testing. If missing, the default file is stress_init.txt in
           the test suite directory.

       •   --stress-mode=mode

           This option indicates the test order in stress-test mode. The
           mode value is either random to select tests in random order
           or seq to run tests in each thread in the order specified in
           the test list file. The default mode is random.

       •   --stress-suite-basedir=path

           This option is required.  path is the directory that has the
           t and r subdirectories containing the test case and result
           files. This directory is also the default location of the
           stress-test.txt file that contains the list of tests. (A
           different location can be specified with the
           --stress-tests-file option.)

       •   --stress-tests-file[=file_name]

           Use this option to run the stress tests.  file_name is the
           location of the file that contains the list of tests. If
           file_name is omitted, the default file is stress-test.txt in
           the stress suite directory. (See --stress-suite-basedir.)

       •   --suite=suite_name

           Run the named test suite. The default name is main (the
           regular test suite located in the mysql-test directory).

       •   --test-count=N

           The number of tests to execute before exiting.

       •   --test-duration=N
