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


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:

Can send SQL statements to MySQL servers for execution
Can execute external shell commands
Can test whether the result from a 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.

mysqltest supports the following options:

--help, -?

Display a help message and exit.

--basedir=dir_name, -b dir_name

The base directory for tests.

--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.


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

--compress, -C

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


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

--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'.


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


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

--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. This option was added in MySQL 4.1.23, 5.0.30, and 5.1.7.


The directory to use for log files. This option was added in MySQL 5.1.14.


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.


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.


Do not read default options from any option files.

--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.


Use the prepared-statement protocol for communication.


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.

--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.
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 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.

--silent, -s

Suppress all normal output.


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).


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.

--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

The file where the timing in microseconds is written.

--tmpdir=dir_name, -t dir_name

The temporary directory where socket files are put.

--user=user_name, -u user_name

The MySQL username to use when connecting to the server.

--verbose, -v

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

--version, -V

Display version information and exit.


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