NAME         top

       mariadb-test - program to run test cases (mysqltest is now a
       symlink to mariadb-test)
       mysqltest_embedded - program to run embedded test cases

SYNOPSIS         top

       mysqltest [options] [db_name]

       mysqltest_embedded [options] [db_name]

DESCRIPTION         top

       The mysqltest program runs a test case against a MariaDB 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 MariaDB 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 MariaDB is
           compiled with support for libmysqld. (In this case, the
           executable is named mysqltest_embedded rather than

       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:

       •   --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.

       •   --connect-timeout=num

           This can be used to set the MYSQL_OPT_CONNECT_TIMEOUT
           parameter of mysql_options to change the number of seconds
           before an unsuccessful connection attempt times out.

       •   --continue-on-error

           Continue test even if we got an error. This is mostly useful
           when testing a storage engine to see what from a test file it
           can execute, or to find all syntax errors in a newly created
           big test file.

       •   --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 MariaDB is built with debugging
           support. The default debug_options value is

       •   --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 MariaDB server on the given host.

       •   --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

       •   --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.

       •   --no-defaults

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

       •   --non-blocking-api

           Use the non-blocking client API for communication.

       •   --overlay-dir=dir_name

           Overlay directory.

       •   --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.

       •   --plugin-dir=dir_name

           Directory for client-side plugins.

       •   --port=port_num, -P port_num

           The TCP/IP port number to use for the connection or 0 for
           default to, in order of preference, my.cnf, $MYSQL_TCP_PORT,
           /etc/services, built-in default (3306).

       •   --prologue=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.

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

           The connection protocol to use for connecting to the server.
           It is useful when the other connection parameters normally
           would cause a protocol to be used other than the one you

       •   --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.

       •   --result-format-version=#

           Version of the result file format to use.

       •   --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.

       •   --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.

           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.

       •   --ssl

           Enable SSL for connection (automatically enabled with other
           flags). Disable with --skip-ssl.

       •   --ssl-ca=name

           CA file in PEM format (check OpenSSL docs, implies --ssl).

       •   --ssl-capath=name

           CA directory (check OpenSSL docs, implies --ssl).

       •   --ssl-cert=name

           X509 cert in PEM format (check OpenSSL docs, implies --ssl).

       •   --ssl-cipher=name

           SSL cipher to use (check OpenSSL docs, implies --ssl).

       •   --ssl-key=name

           X509 key in PEM format (check OpenSSL docs, implies --ssl).

       •   --ssl-crl=name

           Certificate revocation list (check OpenSSL docs, implies

       •   --ssl-crlpath=name

           Certificate revocation list path (check OpenSSL docs, implies

       •   --ssl-verify-server-cert

           Verify server's "Common Name" in its cert against hostname
           used when connecting. This option is disabled by default.

       •   --suite-dir=dir_name

           Suite directory.

       •   --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 microseconds spent running the test
           will be written to this file. This is used by
  for its reporting.

       •   --tmpdir=dir_name, -t dir_name

           The temporary directory where socket files are created.

       •   --user=user_name, -u user_name

           The MariaDB 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.
