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_embedded is similar but used for testing the embedded server. Both programs are 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 mysql-test-run.pl 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:
Display a help message and exit.
The base directory for the tests.
The number of times to execute the tests.
The database to use.
Write a debugging log if MySQL is built with debugging
support. The default
debug_options value is

The password to use when connecting to the server. If you
use the short option form (
cannot have a space between the option
and the password. If you omit the

the command line, you are prompted for one.
The TCP/IP port number to use for the connection.
Argument to send to the embedded server.
Show all test names.
Be more silent.
The socket file to use when connecting to
localhost (which is the default host).
The option is used when called from mysql-test-run.pl, 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.
The MySQL user name to use when connecting to the server.
The data directory for tests. The default is
