       mysqltest [options] [db_name]

       mysqltest_embedded [options] [db_name]


       The mysqltest program runs a test case against a MySQL server and
       optionally compares the output with a result file. This program reads
       input written in a special test language. Typically, you invoke
       mysqltest via rather than invoking it directly.

       mysqltest_embedded is similar but is built with support for the
       libmysqld embedded server.

       Features of mysqltest:

       o   Can send SQL statements to MySQL servers for execution

       o   Can execute external shell commands

       o   Can test whether the result from an SQL statement or shell command
           is as expected

       o   Can connect to one or more standalone mysqld servers and switch
           between connections

       o   Can connect to an embedded server (libmysqld), if MySQL is compiled
           with support for libmysqld. (In this case, the executable is named
           mysqltest_embedded rather than mysqltest.)

       By default, mysqltest reads the test case on the standard input. To run
       mysqltest this way, you normally invoke it like this:

           shell> mysqltest [options] [db_name] < test_file

       You can also name the test case file with a --test-file=file_name

       The exit value from mysqltest is 0 for success, 1 for failure, and 62
       if it skips the test case (for example, if after checking some
       preconditions it decides not to run the test).

       mysqltest supports the following options:

       o   --help, -?

           Display a help message and exit.

       o   --basedir=dir_name, -b dir_name

           The base directory for tests.

       o   --big-test, -B

           Define the mysqltest variable $BIG_TEST as 1. This option was
           removed in MySQL 4.1.23, 5.0.30, and 5.1.13.

       o   --character-sets-dir=path

           The directory where character sets are installed. This option was
           added in MySQL 4.1.23, 5.0.32, and 5.1.13.

       o   --compress, -C

           Compress all information sent between the client and the server if
           both support compression.

       o   --cursor-protocol

           Use cursors for prepared statements (implies --ps-protocol). This
           option was added in MySQL 5.0.19.

       o   --database=db_name, -D db_name

           The default database to use.

       o   --debug[=debug_options], -#[debug_options]

           Write a debugging log if MySQL is built with debugging support. The
           default debug_options value is 'd:t:S:i:O,/tmp/mysqltest.trace'.

       o   --debug-check

           Print some debugging information when the program exits. This
           option was added in MySQL 5.1.21.

       o   --debug-info

           Print debugging information and memory and CPU usage statistics
           when the program exits. This option was added in MySQL 5.1.14.

       o   --host=host_name, -h host_name

           Connect to the MySQL server on the given host.

       o   --include=file_name, -i file_name

           Include the contents of the given file before processing the
           contents of the test file. The included file should have the same
           format as other mysqltest test files. This option has the same
           effect as putting a --source file_name command as the first line of
           the test file. This option was added in MySQL 4.1.23, 5.0.30, and

       o   --logdir=dir_name

           The directory to use for log files. This option was added in MySQL

       o   --mark-progress

           Write the line number and elapsed time to test_file.progress. This
           option was added in MySQL 4.1.23, 5.0.30, and 5.1.12.

       o   --max-connect-retries=num

           The maximum number of connection attempts when connecting to
           server. This option was added in MySQL 4.1.23, 5.0.23, and 5.1.11.

       o   --no-defaults

           Do not read default options from any option files.

       o   --password[=password], -p[password]

           The password to use when connecting to the server. If you use the
           short option form (-p), you cannot have a space between the option
           and the password. If you omit the password value following the
           --password or -p option on the command line, you are prompted for

       o   --port=port_num, -P port_num

           The TCP/IP port number to use for the connection.

       o   --ps-protocol

           Use the prepared-statement protocol for communication.

       o   --quiet

           Suppress all normal output. This is a synonym for --silent.

       o   --record, -r

           Record the output that results from running the test file into the
           file named by the --result-file option, if that option is given.

       o   --result-file=file_name, -R file_name

           This option specifies the file for test case expected results.
           --result-file, together with --record, determines how mysqltest
           treats the test actual and expected results for a test case:

           o   If the test produces no results, mysqltest exits with an error
               message to that effect.

           o   Otherwise, if --result-file is not given, mysqltest sends test
               results to the standard output.

           o   With --result-file but not --record, mysqltest reads the
               expected results from the given file and compares them with the
               actual results. If the results do not match, mysqltest writes a
               .reject file in the same directory as the result file and exits
               with an error.

           o   With both --result-file and --record, mysqltest updates the
               given file by writing the actual test results to it.

       o   --server-arg=value, -A value

           Pass the argument as an argument to the embedded server. For
           example, --server-arg=--tmpdir=/tmp or --server-arg=--core. Up to
           64 arguments can be given.

       o   --server-file=file_name, -F file_name

           Read arguments for the embedded server from the given file. The
           file should contain one argument per line.

       o   --silent, -s

           Suppress all normal output.

       o   --skip-safemalloc

           Do not use memory allocation checking.

       o   --sleep=num, -T num

           Cause all sleep commands in the test case file to sleep num
           seconds. This option does not affect real_sleep commands.

           As of MySQL 5.0.23, an option value of 0 can be used, which
           effectively disables sleep commands in the test case.

       o   --socket=path, -S path

           The socket file to use when connecting to localhost (which is the
           default host).

       o   --sp-protocol

           Execute DML statements within a stored procedure. For every DML
           statement, mysqltest creates and invokes a stored procedure that
           executes the statement rather than executing the statement
           directly. This option was added in MySQL 5.0.19.

       o   --test-file=file_name, -x file_name

           Read test input from this file. The default is to read from the
           standard input.

       o   --timer-file=file_name, -m file_name

           The file where the timing in microseconds is written.

       o   --tmpdir=dir_name, -t dir_name

           The temporary directory where socket files are put.

       o   --user=user_name, -u user_name

           The MySQL user name to use when connecting to the server.

       o   --verbose, -v

           Verbose mode. Print out more information what the program does.

       o   --version, -V

           Display version information and exit.

       o   --view-protocol

           Every SELECT statement is wrapped inside a view. This option was
           added in MySQL 5.0.19.
