Описание (Description)
The mysqltest program runs a test case against a MariaDB 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 MariaDB 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 MariaDB 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.
• --connect-timeout=num
This can be used to set the MYSQL_OPT_CONNECT_TIMEOUT
parameter of mysql_options to change the number of seconds
before an unsuccessful connection attempt times out.
• --continue-on-error
Continue test even if we got an error. This is mostly useful
when testing a storage engine to see what from a test file it
can execute, or to find all syntax errors in a newly created
big test file.
• --cursor-protocol
Use cursors for prepared statements.
• --database=db_name, -D db_name
The default database to use.
• --debug[=debug_options], -#[debug_options]
Write a debugging log if MariaDB is built with debugging
support. The default debug_options value is
´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 MariaDB server on the given host.
• --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.
• --no-defaults
Do not read default options from any option files. If used,
this must be the first option.
• --non-blocking-api
Use the non-blocking client API for communication.
• --overlay-dir=dir_name
Overlay directory.
• --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.
• --plugin-dir=dir_name
Directory for client-side plugins.
• --port=port_num, -P port_num
The TCP/IP port number to use for the connection or 0 for
default to, in order of preference, my.cnf, $MYSQL_TCP_PORT,
/etc/services, built-in default (3306).
• --prologue=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.
• --protocol={TCP|SOCKET|PIPE|MEMORY}
The connection protocol to use for connecting to the server.
It is useful when the other connection parameters normally
would cause a protocol to be used other than the one you
want.
• --ps-protocol
Use the prepared-statement protocol for communication.
• --quiet
Suppress all normal output. This is a synonym for --silent.
• --record, -r
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.
• --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.
• --result-format-version=#
Version of the result file format to use.
• --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.
• --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.
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.
• --ssl
Enable SSL for connection (automatically enabled with other
flags). Disable with --skip-ssl.
• --ssl-ca=name
CA file in PEM format (check OpenSSL docs, implies --ssl).
• --ssl-capath=name
CA directory (check OpenSSL docs, implies --ssl).
• --ssl-cert=name
X509 cert in PEM format (check OpenSSL docs, implies --ssl).
• --ssl-cipher=name
SSL cipher to use (check OpenSSL docs, implies --ssl).
• --ssl-key=name
X509 key in PEM format (check OpenSSL docs, implies --ssl).
• --ssl-crl=name
Certificate revocation list (check OpenSSL docs, implies
--ssl).
• --ssl-crlpath=name
Certificate revocation list path (check OpenSSL docs, implies
--ssl).
• --ssl-verify-server-cert
Verify server's "Common Name" in its cert against hostname
used when connecting. This option is disabled by default.
• --suite-dir=dir_name
Suite directory.
• --tail-lines=nn
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.
• --test-file=file_name, -x file_name
Read test input from this file. The default is to read from
the standard input.
• --timer-file=file_name, -m file_name
If given, the number of microseconds spent running the test
will be written to this file. This is used by
mysql-test-run.pl for its reporting.
• --tmpdir=dir_name, -t dir_name
The temporary directory where socket files are created.
• --user=user_name, -u user_name
The MariaDB 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.
