mysqltest_embedded is similar but is built with support for the libmysqld embedded server.
Features of 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:
Display a help message and exit.
The base directory for tests.
The directory where character sets are installed.
Compress all information sent between the client and the server if both support compression.
Use cursors for prepared statements.
The default database to use.
Write a debugging log if MySQL is built with debugging support. The default debug_options value is 'd:t:S:i:O,/tmp/mysqltest.trace'.
Print some debugging information when the program exits.
Print debugging information and memory and CPU usage statistics when the program exits.
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 --source file_name command as the first line of the test file.
The directory to use for log files.
Write the line number and elapsed time to test_file.progress.
The maximum number of connection attempts when connecting to server.
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.
Do not read default options from any option files. If used, this must be the first option.
The directory in which to look for plugins. It may be necessary to specify this option if the default_auth argument is used for the connect() command to specify an authentication plugin but mysqltest does not find it. This option was added in MySQL 5.5.7.
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.
The TCP/IP port number to use for the connection.
Choose the protocol for communication with the server. SOCKET is default.
The --protocol option is available from MySQL 5.1.51. It is ignored if running with the embedded server.
Use the prepared-statement protocol for communication.
Suppress all normal output. This is a synonym for --silent.
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.
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:
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.
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.
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.
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.
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.
Read test input from this file. The default is to read from the standard input.
If given, the number of millisecond spent running the test will be written to this file. This is used by mysql-test-run.pl for its reporting.
The temporary directory where socket files are created.
The MySQL user name to use when connecting to the server.
Verbose mode. Print out more information about what the program does.
Display version information and exit.
Every SELECT statement is wrapped inside a view. This option was added in MySQL 5.0.19.
