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.
