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 via
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:
· 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 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:
· --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.
´d:t:S:i:O,/tmp/mysqltest.trace´.
· --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 MySQL server on the given host.
· --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.
· --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 server.
· --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.
· --no-defaults
Do not read default options from any option files. If used, this must be the first option.
· --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.
· --ps-protocol
· --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.
· --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.
· --skip-safemalloc
Do not use memory allocation checking.
· --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.
· --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.
· --tail-lines=nn
Specify how many lines of the result to include in the output if the test fails because an SQL statement
The temporary directory where socket files are created.
· --user=user_name, -u user_name
The MySQL 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. This option was added in MySQL 5.0.19.
