NAME

       mysqltest - program to run test cases
       mysqltest_embedded - program to run embedded test cases

SYNOPSIS

       mysqltest [options] [db_name]

       mysqltest_embedded [options] [db_name]

DESCRIPTION

       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 using mysql-test-run.pl rather than invoking it directly.

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

       Features of mysqltest:

       ·   Can send SQL statements to MySQL servers for execution

       ·   Can execute external shell commands

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

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

       ·   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 option.

       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:

       ·   --help, -?

           Display a help message and exit.

       ·   --basedir=dir_name, -b dir_name

           The base directory for tests.

       ·   --character-sets-dir=path

           The directory where character sets are installed.

       ·   --compress, -C

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

       ·   --cursor-protocol

           Use cursors for prepared statements.

       ·   --database=db_name, -D db_name

           The default database to use.

       ·   --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'.

       ·   --debug-check

           Print some debugging information when the program exits.

       ·   --debug-info

           Print debugging information and memory and CPU usage statistics when the program
           exits.

       ·   --host=host_name, -h host_name

           Connect to the MySQL server on the given host.

       ·   --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.

       ·   --logdir=dir_name

           The directory to use for log files.

       ·   --mark-progress

           Write the line number and elapsed time to test_file.progress.

       ·   --max-connect-retries=num

           The maximum number of connection attempts when connecting to server.

       ·   --max-connections=num

           The maximum number of simultaneous server connections per client (that is, per test).
           If not set, the maximum is 128. Minimum allowed limit is 8, maximum is 5120.

           This option is available from MySQL 5.1.45.

       ·   --no-defaults

           Do not read default options from any option files. If used, this must be the first
           option.

       ·   --plugin-dir=path

           The directory in which to look for plugins. It may be necessary to specify this option
           if the default_auth argument is used for the connect() command to specify an
           authentication plugin but mysqltest does not find it. This option was added in MySQL
           5.5.7.

       ·   --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 one.

       ·   --port=port_num, -P port_num

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

       ·   --protocol={TCP|SOCKET|PIPE|MEMORY}

           Choose the protocol for communication with the server.  SOCKET is default.

           The --protocol option is available from MySQL 5.1.51. It is ignored if running with
           the embedded server.

       ·   --ps-protocol

           Use the prepared-statement protocol for communication.

       ·   --quiet

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

       ·   --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. It is an error to use this option
           without also using --result-file.

       ·   --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:

           ·   If the test produces no results, mysqltest exits with an error message to that
               effect, unless --result-file is given and the named file is an empty file.

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

           ·   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, outputs
               a diff of the two files, and exits with an error.

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

       ·   --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.

       ·   --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.

       ·   --server-public-key-path=file_name

           The path name to a file containing the server RSA public key. The file must be in PEM
           format. The public key is used for RSA encryption of the client password for
           connections to the server made using accounts that authenticate with the
           sha256_password plugin. This option is ignored for client accounts that do not
           authenticate with that plugin. It is also ignored if password encryption is not
           needed, as is the case when the client connects to the server using an SSL connection.

           The server sends the public key to the client as needed, so it is not necessary to use
           this option for RSA password encryption to occur. It is more efficient to do so
           because then the server need not send the key.

           For additional discussion regarding use of the sha256_password plugin, including how
           to get the RSA public key, see The SHA-256 Authentication Plugin[1].

           This option is available only if MySQL was built using OpenSSL. It was added in MySQL
           5.6.6 under the name --server-public-key and renamed in 5.6.7 to
           --server-public-key-path.

       ·   --silent, -s

           Suppress all normal output.

       ·   --skip-safemalloc

           Do not use memory allocation checking.

       ·   --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.

       ·   --socket=path, -S path

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

       ·   --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.

       ·   --tail-lines=nn

           Specify how many lines of the result to include in the output if the test fails
           because an SQL statement fails. The default is 0, meaning no lines of result printed.

       ·   --test-file=file_name, -x file_name

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

       ·   --timer-file=file_name, -m file_name

           If given, the number of millisecond spent running the test will be written to this
           file. This is used by mysql-test-run.pl for its reporting.

       ·   --tmpdir=dir_name, -t dir_name

           The temporary directory where socket files are created.

       ·   --user=user_name, -u user_name

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

       ·   --verbose, -v

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

       ·   --version, -V

           Display version information and exit.

       ·   --view-protocol

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