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
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
libmysqld. (In this case, the
executable is named mysqltest_embedded
rather than mysqltest.)
You can also name the test case file with a
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:
Display a help message and exit.
The base directory for tests.
Define the mysqltest variable
$BIG_TEST as 1. This option was removed
in MySQL 4.1.23, 5.0.30, and 5.1.13.
The directory where character sets are installed. This option was added in MySQL 4.1.23, 5.0.32, and 5.1.13.
Compress all information sent between the client and the server if both support compression.
Use cursors for prepared statements (implies
--ps-protocol). This option was added in
The default database to use.
Write a debugging log if MySQL is built with debugging
support. The default
debug_options value is
Print some debugging information when the program exits. This option was added in MySQL 5.1.21.
Print debugging information and memory and CPU usage statistics when the program exits. This option was added in MySQL 5.1.14.
Connect to the MySQL server on the given host.
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
the first line of the test file. This option was added in
MySQL 4.1.23, 5.0.30, and 5.1.7.
The directory to use for log files. This option was added in MySQL 5.1.14.
Write the line number and elapsed time to
This option was added in MySQL 4.1.23, 5.0.30, and 5.1.12.
The maximum number of connection attempts when connecting to server. This option was added in MySQL 4.1.23, 5.0.23, and 5.1.11.
Do not read default options from any option files.
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
password value following the
-p option on
the command line, you are prompted for one.
The TCP/IP port number to use for the connection.
Use the prepared-statement protocol for communication.
Record the output that results from running the test file
into the file named by the
option, if that option is given.
This option specifies the file for test case expected
--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.
--result-file is not
given, mysqltest sends test results
to the standard output.
--result-file but not
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 and exits with an error.
updates the given file by writing the actual test
results to it.
Pass the argument as an argument to the embedded server. For
--server-arg=--core. Up to 64 arguments can
Read arguments for the embedded server from the given file. The file should contain one argument per line.
Suppress all normal output.
Do not use memory allocation checking.
sleep commands in the test case
file to sleep
num seconds. This
option does not affect
As of MySQL 5.0.23, an option value of 0 can be used, which
sleep commands in
the test case.
The socket file to use when connecting to
localhost (which is the default host).
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. This option was added in MySQL 5.0.19.
Read test input from this file. The default is to read from the standard input.
The file where the timing in microseconds is written.
The temporary directory where socket files are put.
The MySQL user name to use when connecting to the server.
Verbose mode. Print out more information what the program does.
Display version information and exit.
SELECT statement is wrapped inside
a view. This option was added in MySQL 5.0.19.
