MARIADB-TEST(1)

✨ MARIADB-TEST(1) ✨

okay bestie, welcome to the MariaDB Database System corner of the man pages 💖 this is the mariadb-test page and it is A LOT, so grab a snack 🍓

🌸 NAME 🌸

mariadb-test — program to run test cases (mariadb-test is now a symlink to mariadb-test)

mariadb-test-embedded — program to run embedded test cases

---

🦋 SYNOPSIS 🦋

mariadb-test [options] [db_name]

mariadb-test-embedded [options] [db_name]

---

💅 DESCRIPTION 💅

So. The mariadb-test program runs a test case against a MariaDB server, and optionally it compares the output with a result file. It reads input written in a special test language, no cap. Typically you invoke mariadb-test via mariadb-test-run.pl rather than invoking it directly — that's just how the girlies do it. 🫶

mariadb-test-embedded is similar but it's built with support for the libmariadbd embedded server.

👑 Features of mariadb-test

• 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 mariadbd servers and switch between connections
• Can connect to an embedded server (libmariadbd), if MariaDB is compiled with support for libmariadbd. (In this case, the executable is named mariadb-test-embedded rather than mariadb-test.)

By default, mariadb-test reads the test case on the standard input. To run mariadb-test this way, you normally invoke it like this:

shell> mariadb-test [options] [db_name] < test_file

You can also name the test case file with a --test-file=file_name option.

The exit value from mariadb-test 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). bestie, those numbers MATTER, ok? 💀

mariadb-test supports the following options:

---

✨ 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. literally the "keep going bestie" option 🫶
• --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/mariadb-test.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. (first. bestie. don't fight it.)
• --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 mariadb-test 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 mariadb-test treats the test actual and expected results for a test case:
  • If the test produces no results, mariadb-test 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, mariadb-test sends test results to the standard output.
  • With --result-file but not --record, mariadb-test reads the expected results from the given file and compares them with the actual results. If the results do not match, mariadb-test 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, mariadb-test 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, mariadb-test 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 mariadb-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.
