MYSQLTEST(1)                                          MySQL Database System                                         MYSQLTEST(1)



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:

       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 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:

       o   --help, -?

           Display a help message and exit.

       o   --basedir=dir_name, -b dir_name

           The base directory for tests.

       o   --character-sets-dir=path

           The directory where character sets are installed.

       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.

       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.

       o   --debug-info

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

       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.

       o   --logdir=dir_name

           The directory to use for log files.

       o   --mark-progress

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

       o   --max-connect-retries=num

           The maximum number of connection attempts when connecting to server.

       o   --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.

       o   --no-defaults

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

       o   --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.

       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 one.

       o   --port=port_num, -P port_num

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

       o   --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.

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

       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, unless --result-file is
               given and the named file is an empty file.

           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, outputs a diff of the two files, 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.

       o   --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.

       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

           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.

       o   --tmpdir=dir_name, -t dir_name

           The temporary directory where socket files are created.

       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 about 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.
