           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 test.

       ·   --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

       ·   --mysqltest=path

           The path name to the mysqltest program.

           This option is required.  path is the directory where all client

       ·   --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

       ·   --stress-mode=mode

           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.
