mysql_client_test — Test Client API

The mysql_client_test program is used for testing aspects of the MySQL client API that cannot be tested using mysqltest and its test language.

mysql_client_test is run as part of the test suite.

The source code for the programs can be found in in tests/mysql_client_test.c in a source distribution. The program serves as a good source of examples illustrating how to use various features of the client API.

mysql_client_test is used in a test by the same name in the main tests suite of but may also be run directly. Unlike the other programs listed here, it does not read an external description of what tests to run. Instead, all tests are coded into the program, which is written to cover all aspects of the C language API.

mysql_client_test supports the following options:

  • --help, -?

    Display a help message and exit.

  • --basedir=dir_name, -b dir_name

    The base directory for the tests.

  • --count=count, -t count

    The number of times to execute the tests.

  • --database=db_name, -D db_name

    The 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:o,/tmp/mysql_client_test.trace'.

  • --getopt-ll-test=option, -g option

    Option to use for testing bugs in the getopt library.

  • --host=host_name, -h host_name

    Connect to the MySQL server on the given host.

  • --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.

  • --show-tests, -T

    Show all test names.

  • --silent, -s

    Be more silent.

  • --socket=path, -S path

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

  • --testcase, -c

    The option is used when called from, so that mysql_client_test may optionally behave in a different way than if called manually, for example by skipping some tests. Currently, there is no difference in behavior but the option is included to make this possible.

  • --user=user_name, -u user_name

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

  • --vardir=dir_name, -v dir_name

    The data directory for tests. The default is mysql-test/var.
