NAME top

       mysql-test-run.pl - run MariaDB test suite

SYNOPSIS top


       mysql-test-run.pl [options]

DESCRIPTION top

The mysql-test-run.pl Perl script is the main application used to
run the MariaDB test suite. It invokes mysqltest to run
individual test cases.

Invoke mysql-test-run.pl in the mysql-test directory like this:

shell> mysql-test-run.pl [options] [test_name] ...

Each test_name argument names a test case. The test case file
that corresponds to the test name is t/test_name.test.

For each test_name argument, mysql-test-run.pl runs the named
test case. With no test_name arguments, mysql-test-run.pl runs
all .test files in the t subdirectory.

If no suffix is given for the test name, a suffix of .test is
assumed. Any leading path name is ignored. These commands are
equivalent:

shell> mysql-test-run.pl mytest
shell> mysql-test-run.pl mytest.test
shell> mysql-test-run.pl t/mytest.test

A suite name can be given as part of the test name. That is, the
syntax for naming a test is:

[suite_name.]test_name[.suffix]

If a suite name is given, mysql-test-run.pl looks in that suite
for the test. The test file corresponding to a test named
suite_name.test_name is found in
suite/suite_name/t/test_name.test. There is also an implicit
suite name main for the tests in the top t directory. With no
suite name, mysql-test-run.pl looks in the default list of suites
for a match and runs the test in any suites where it finds the
test. Suppose that the default suite list is main, binlog, rpl,
and that a test mytest.test exists in the main and rpl suites.
With an argument of mytest or mytest.test, mysql-test-run.pl will
run mytest.test from the main and rpl suites.

To run a family of test cases for which the names share a common
prefix, use the --do-test=prefix option. For example,
--do-test=rpl runs the replication tests (test cases that have
names beginning with rpl). --skip-test has the opposite effect
of skipping test cases for which the names share a common prefix.

The argument for the --do-test and --skip-test options also
allows more flexible specification of which tests to perform or
skip. If the argument contains a pattern metacharacter other than
a lone period, it is interpreted as a Perl regular expression and
applies to test names that match the pattern. If the argument
contains a lone period or does not contain any pattern
metacharacters, it is interpreted the same way as previously and
matches test names that begin with the argument value. For
example, --do-test=testa matches tests that begin with testa,
--do-test=main.testa matches tests in the main test suite that
begin with testa, and --do-test=main.*testa matches test names
that contain main followed by testa with anything in between. In
the latter case, the pattern match is not anchored to the
beginning of the test name, so it also matches names such as
xmainytesta.

To perform setup prior to running tests, mysql-test-run.pl needs
to invoke mysqld with the --bootstrap and --skip-grant-tables
options. If MySQL was configured with the --disable-grant-options
option, --bootstrap, --skip-grant-tables, and --init-file will be
disabled. To handle this, set the MYSQLD_BOOTSTRAP environment
variable to the full path name of a server that has all options
enabled. mysql-test-run.pl will use that server to perform
setup; it is not used to run the tests.

The init_file test will fail if --init-file is disabled. This is
an expected failure that can be handled as follows:

shell> export MYSQLD_BOOTSTRAP
shell> MYSQLD_BOOTSTRAP=/full/path/to/mysqld
shell> make test force="--skip-test=init_file"

To run mysql-test-run.pl on Windows, you´ll need either Cygwin or
ActiveState Perl to run it. You may also need to install the
modules required by the script. To run the test script, change
location into the mysql-test directory, set the MTR_VS_CONFIG
environment variable to the configuration you selected earlier
(or use the --vs-config option), and invoke mysql-test-run.pl.
For example (using Cygwin and the bash shell):

shell> cd mysql-test
shell> export MTR_VS_CONFIG=debug
shell> ./mysqltest-run.pl --force --timer
shell> ./mysqltest-run.pl --force --timer --ps-protocol

mysql-test-run.pl uses several environment variables. Some of
them are listed in the following table. Some of these are set
from the outside and used by mysql-test-run.pl, others are set by
mysql-test-run.pl instead, and may be referred to in tests.
┌──────────────────┬────────────────────────────┐
│ Variable │ Meaning │
├──────────────────┼────────────────────────────┤
│ MTR_VERSION │ If set to 1, will run │
│ │ the older version 1 of │
│ │ mysql-test-run.pl. This │

│ │ supported. │
├──────────────────┼────────────────────────────┤
│ MTR_MEM │ If set to anything, will │

│ │ --mem │
│ │ option │
├──────────────────┼────────────────────────────┤
│ MTR_PARALLEL │ If set, defines number │

│ │ the server │
├──────────────────┼────────────────────────────┤
│ MTR_PORT_BASE │ If set, defines which port │

│ │ the server │
├──────────────────┼────────────────────────────┤
│ MTR_NAME_TIMEOUT │ Setting of a timeout in │

└──────────────────┴────────────────────────────┘

The variable MTR_PORT_BASE was added in MySQL 5.1.45 as a more
logical replacement for MTR_BUILD_THREAD. It gives the actual
port number directly (will be rounded down to a multiple of 10).
If you use MTR_BUILD_THREAD, the port number is found by
multiplying this by 10 and adding 10000.

Tests sometimes rely on certain environment variables being
defined. For example, certain tests assume that MYSQL_TEST is
defined so that mysqltest can invoke itself with exec
$MYSQL_TEST.

Other tests may refer to the last three variables listed in the
preceding table, to locate files to read or write. For example,
tests that need to create files will typically put them in
$MYSQL_TMP_DIR/file_name.

If you are running mysql-test-run.pl version 1 by setting
MTR_VERSION, note that this only affects the test driver, not the
test client (and its language) or the tests themselves.

A few tests might not run with version 1 because they depend on
some feature of version 2. You may have those tests skipped by
adding the test name to the file lib/v1/incompatible.tests. This
feature is available from MySQL 5.1.40.

mysql-test-run.pl supports the options in the following list. An
argument of -- tells mysql-test-run.pl not to process any
following arguments as options.

• --help, -h

Display a help message and exit.

• --big-test

Allow tests marked as "big" to run. Tests can be thus marked
by including the line --source include/big_test.inc, and they
will only be run if this option is given, or if the
environment variable BIG_TEST is set to 1. Repeat this option
twice to run only "big" tests.

This is typically used for tests that take a very long to
run, or that use many resources, so that they are not
suitable for running as part of a normal test suite run.

• --boot-dbx

Run the mysqld server used for bootstrapping the database
through the dbx debugger.

• --boot-ddd

Run the mysqld server used for bootstrapping the database
through the ddd debugger.

• --boot-gdb

Run the mysqld server used for bootstrapping the database
through the gdb debugger.

• --[mtr-]build-thread=number

Specify a number to calculate port numbers from. The formula
is 10 * build_thread + 10000. Instead of a number, it can be
set to auto, which is also the default value, in which case
mysql-test-run.pl will allocate a number unique to this host.

The value (number or auto) can also be set with the
MTR_BUILD_THREAD environment variable.

The more logical --port-base is supported as an alternative.

• --callgrind

Instructs valgrind to use callgrind.

• --check-testcases

Check test cases for side effects. This is done by checking
system state before and after each test case; if there is any
difference, a warning to that effect will be written, but the
test case will not be marked as failed because of it. This
check is enabled by default.

• --client-bindir=path

The path to the directory where client binaries are located.

• --client-dbx

Start mysqltest in the dbx debugger.

• --client-ddd

Start mysqltest in the ddd debugger.

• --client-debugger=debugger

Start mysqltest in the named debugger.

• --client-gdb

Start mysqltest in the gdb debugger.

• --client-libdir=path

The path to the directory where client libraries are located.

• --combination=value

Extra options to pass to mysqld. The value should consist of
one or more comma-separated mysqld options. This option is
similar to --mysqld but should be given two or more times.
mysql-test-run.pl executes multiple test runs, using the
options for each instance of --combination in successive
runs. If --combination is given only once, it has no effect.
For test runs specific to a given test suite, an alternative
to the use of --combination is to create a combinations file
in the suite directory. The file should contain a section of
options for each test run.

• --comment=str

Write str to the output within lines filled with #, as a form
of banner.

• --compress

Compress all information sent between the client and the
server if both support compression.

• --cursor-protocol

Use the cursor protocol between client and server (implies
--ps-protocol).

• --dbx

Start the mysqld(s) in the dbx debugger.

• --ddd

Start the mysqld(s) in the ddd debugger.

• --debug

Dump trace output for all clients and servers.

• --debug-common

Same as --debug, but sets the 'd' debug flags to
"query,info,error,enter,exit".

• --debug-server

Use debug version of server, but without turning on tracing.

• --debugger=debugger

Start mysqld using the named debugger.

• --debug-sync-timeout=N

Controls whether the Debug Sync facility for testing and
debugging is enabled. The option value is a timeout in
seconds. The default value is 300. A value of 0 disables
Debug Sync. The value of this option also becomes the default
timeout for individual synchronization points.

mysql-test-run.pl passes --loose-debug-sync-timeout=N to
mysqld. The --loose prefix is used so that mysqld does not
fail if Debug Sync is not compiled in.

• --defaults-file=file_name

Use the named file as fixed config file template for all
tests.

• --defaults_extra_file=file_name

Add setting from the named file to all generated configs.

• --do-test=prefix|regex

Run all test cases having a name that begins with the given
prefix value, or fulfils the regex. This option provides a
convenient way to run a family of similarly named tests.

The argument for the --do-test option also allows more
flexible specification of which tests to perform. If the
argument contains a pattern metacharacter other than a lone
period, it is interpreted as a Perl regular expression and
applies to test names that match the pattern. If the argument
contains a lone period or does not contain any pattern
metacharacters, it is interpreted the same way as previously
and matches test names that begin with the argument value.
For example, --do-test=testa matches tests that begin with
testa, --do-test=main.testa matches tests in the main test
suite that begin with testa, and --do-test=main.*testa
matches test names that contain main followed by testa with
anything in between. In the latter case, the pattern match is
not anchored to the beginning of the test name, so it also
matches names such as xmainytestz.

• --dry-run

Don't run any tests, print the list of tests that were
selected for execution.

• --embedded-server

Use a version of mysqltest built with the embedded server.

• --enable-disabled

Ignore any disabled.def file, and also run tests marked as
disabled. Success or failure of those tests will be reported
the same way as other tests.

• --experimental=file_name

Specify a file that contains a list of test cases that should
be displayed with the [ exp-fail ] code rather than [ fail ]
if they fail.

For an example of a file that might be specified via this
option, see mysql-test/collections/default.experimental.

• --extern option=value

Use an already running server. The option/value pair is what
is needed by the mysql client to connect to the server. Each
--extern option can only take one option/value pair as an
argument, so you need to repeat --extern for each pair
needed. Example:

./mysql-test-run.pl --extern socket=var/tmp/mysqld.1.sock alias

Note: If a test case has an .opt file that requires the
server to be restarted with specific options, the file will
not be used. The test case likely will fail as a result.

• --fast

Do not perform controlled shutdown when servers need to be
restarted or at the end of the test run. This is equivalent
to using --shutdown-timeout=0.

• --force-restart

Always restart servers between tests.

• --force

Normally, mysql-test-run.pl exits if a test case fails.
--force causes execution to continue regardless of test case
failure.

• --gcov

Collect coverage information after the test. The result is a
gcov file per source and header file.

• --gcov-src-dir

Colllect coverage only within the given subdirectory. For
example, if you're only developing the SQL layer, it makes
sense to use --gcov-src-dir=sql.

• --gdb

Start the mysqld(s) in the gdb debugger.

• --gprof

Collect profiling information using the gprof profiling tool.

• --manual-dbx

Use a server that has already been started by the user in the
dbx debugger.

• --manual-ddd

Use a server that has already been started by the user in the
ddd debugger.

• --manual-debug

Use a server that has already been started by the user in a
debugger.

• --manual-gdb

Use a server that has already been started by the user in the
gdb debugger.

• --manual-lldb

Use a server that has already been started by the user in the
lldb debugger.

• --mark-progress

Marks progress with timing (in milliseconds) and line number
in var/log/testname.progress.

• --max-connections=num

The maximum number of simultaneous server connections that
may be used per test. If not set, the maximum is 128. Minimum
allowed limit is 8, maximum is 5120. Corresponds to the same
option for mysqltest.

• --max-save-core=N

Limit the number of core files saved, to avoid filling up
disks in case of a frequently crashing server. Defaults to 5,
set to 0 for no limit. May also be set with the environment
variable MTR_MAX_SAVE_CORE

• --max-save-datadir=N

Limit the number of data directories saved after failed
tests, to avoid filling up disks in case of frequent
failures. Defaults to 20, set to 0 for no limit. May also be
set with the environment variable MTR_MAX_SAVE_DATADIR

• --max-test-fail=N

Stop execution after the specified number of tests have
failed, to avoid using up resources (and time) in case of
massive failures. retries are not counted, nor are failures
of tests marked experimental. Defaults to 10, set to 0 for no
limit. May also be set with the environment variable
MTR_MAX_TEST_FAIL

• --mem

This option is not supported on Windows.

Run the test suite in memory, using tmpfs or ramdisk. This
can decrease test times significantly, in particular if you
would otherwise be running over a remote file system.
mysql-test-run.pl attempts to find a suitable location using
a built-in list of standard locations for tmpfs and puts the
var directory there. This option also affects placement of
temporary files, which are created in var/tmp.

The default list includes /dev/shm. You can also enable this
option by setting the environment variable
MTR_MEM[=dir_name]. If dir_name is given, it is added to the
beginning of the list of locations to search, so it takes
precedence over any built-in locations.

Once you have run tests with --mem within a
mysql-testdirectory, a soflink var will have been set up to
the temporary directory, and this will be re-used the next
time, until the soflink is deleted. Thus, you do not have to
repeat the --mem option next time.

• --mysqld=value

Extra options to pass to mysqld. The value should consist of
one or more comma-separated mysqld options.

• --mysqld-env=VAR=VAL

Specify additional environment settings for "mysqld". Use
additional --mysqld-env options to set more than one
variable.

• --nocheck-testcases

Disable the check for test case side effects; see
--check-testcases for a description.

• --noreorder

Do not reorder tests to reduce number of restarts, but run
them in exactly the order given. If a whole suite is to be
run, the tests are run in alphabetical order, though similar
combinations will be grouped together. If more than one suite
is listed, the tests are run one suite at a time, in the
order listed.

• --notimer

Cause mysqltest not to generate a timing file. The effect of
this is that the report from each test case does not include
the timing in milliseconds as it normally does.

• --nowarnings

Do not look for and report errors and warning in the server
logs.

• --parallel={N|auto}

Run tests using N parallel threads. By default, 1 thread is
used. Use --parallel=auto for auto-setting of N.

• --[mtr-]port-base=P

Specify base of port numbers to be used; a block of 10 will
be allocated. P should be divisible by 10; if it is not, it
will be rounded down. If running with more than one parallel
test thread, thread 2 will use the next block of 10 and so
on.

If the port number is given as auto, which is also the
default, mysql-test-run.pl will allocate a number unique to
this host. The value may also be given with the environment
variable MTR_PORT_BASE.

If both --build-thread and --port-base are used, --port-base
takes precedence.

• --print-testcases

Do not run any tests, but print details about all tests, in
the order they would have been run.

• --ps-protocol

Use the binary protocol between client and server.

• --record

Pass the --record option to mysqltest. This option requires a
specific test case to be named on the command line.

• --reorder

Reorder tests to minimize the number of server restarts
needed. This is the default behavior. There is no guarantee
that a particular set of tests will always end up in the same
order.

• --repeat=N

Run each test N number of times.

• --report-features

First run a "test" that reports MariaDB features, displaying
the output of SHOW ENGINES and SHOW VARIABLES. This can be
used to verify that binaries are built with all required
features.

• --report-times

Report how much time has been spent on different phases of
test execution.

• --retry=N

If a test fails, it is retried up to a maximum of N runs
(default 1). Retries are also limited by the maximum number
of failures before stopping, set with the --retry-failure
option. This option has no effect unless --force is also
used; without it, test execution will terminate after the
first failure.

The --retry and --retry-failure options do not affect how
many times a test repeated with --repeat may fail in total,
as each repetition is considered a new test case, which may
in turn be retried if it fails.

• --retry-failure=N

When using the --retry option to retry failed tests, stop
when N failures have occurred (default 2). Setting it to 0 or
1 effectively turns off retries.

• --shutdown-timeout=SECONDS

Max number of seconds to wait for servers to do controlled
shutdown before killing them. Default is 10.

• --skip-combinations

Do not apply combinations; ignore combinations file or
option.

• --skip-rpl

Skip replication test cases.

• --skip-ssl

Do not start mysqld with support for SSL connections.

• --skip-test=regex|regex

Specify a regular expression to be applied to test case
names. Cases with names that match the expression are
skipped. tests to skip.

The argument for the --skip-test option allows more flexible
specification of which tests to skip. If the argument
contains a pattern metacharacter other than a lone period, it
is interpreted as a Perl regular expression and applies to
test names that match the pattern. See the description of the
--do-test option for details.

• --skip-test-list=FILE

Skip the tests listed in FILE. Each line in the file is an
entry and should be formatted as: <TESTNAME> : <COMMENT>

• --skip-*

--skip-* options not otherwise recognized by
mysql-test-run.pl are passed to the master server.

• --sleep=N

Pass --sleep=N to mysqltest.

• --sp-protocol

Create a stored procedure to execute all queries.

• --ssl

If mysql-test-run.pl is started with the --ssl option, it
sets up a secure connection for all test cases. In this case,
if mysqld does not support SSL, mysql-test-run.pl exits with
an error message: Couldn´t find support for SSL

• --staging-run

Run a limited number of tests (no slow tests). Used for
running staging trees with valgrind.

• --start

Initialize and start servers with the startup settings for
the specified test case. You can use this option to start a
server to which you can connect later. For example, after
building a source distribution you can start a server and
connect to it with the mysql client like this:

shell> cd mysql-test
shell> ./mysql-test-run.pl --start alias &
shell> ../mysql -S ./var/tmp/master.sock -h localhost -u root

If no tests are named on the command line, the server(s) will
be started with settings for the first test that would have
been run without the --start option.

mysql-test-run.pl will stop once the server has been started,
but will terminate if the server dies. If killed, it will
also shut down the server.

• --start-and-exit

Same --start, but mysql-test-run terminates and leaves just
the server running.

• --start-dirty

This is similar to --start, but will skip the database
initialization phase and assume that database files are
already available. Usually this means you must have run
another test first.

• --start-from=test_name

mysql-test-run.pl sorts the list of names of the test cases
to be run, and then begins with test_name.

• --strace

Run the "mysqld" executables using strace. Default options
are -f -o var/log/'mysqld-name'.strace.

• --strace-client

Create strace output for mysqltest, optionally specifying
name and path to the trace program to use.

Example: ./mysql-test-run.pl --strace-client=ktrace

• --strace-option=ARGS

Option to give strace, replaces default option(s).

• --stress=ARGS

Run stress test, providing options to mysql-stress-test.pl.
Options are separated by comma.

• --suite[s]=suite_name...

Comma separated list of suite names to run. The default is:
"main-,archive-,binlog-,csv-,federated-,funcs_1-,funcs_2-,
handler-,heap-,innodb-,innodb_fts-,innodb_zip-,maria-,
multi_source-,optimizer_unfixed_bugs-,parts-,perfschema-,
plugins-,roles-,rpl-,sys_vars-,unit-,vcol-".

• --stop-file=file

If this file is detected, mysqltest will not start new tests
until the file is removed (also MTR_STOP_FILE environment
variable).

• --stop-keep-alive=sec

Works with --stop-file, print messages every sec seconds when
mysqltest is waiting to remove the file (for buildbot) (also
MTR_STOP_KEEP_ALIVE environment variable).

• --suite-timeout=minutes

Specify the maximum test suite runtime in minutes. The
default is 360.

• --testcase-timeout

Specify the maximum test case runtime in minutes. The default
is 15.

• --timediff

Used with --timestamp, also print time passed since the
previous test started.

• --timer

Cause mysqltest to generate a timing file. The default file
is named ./var/log/timer.

• --timestamp

Prints a timestamp before the test case name in each test
report line, showing when the test ended.

• --tmpdir=path

The directory where temporary file are stored. The default
location is ./var/tmp. The environment variable MYSQL_TMP_DIR
will be set to the path for this directory, whether it has
the default value or has been set explicitly. This may be
referred to in tests.

• --user=user_name

The MariaDB user name to use when connecting to the server
(default root).

• --user-args

In combination with start* and no test name, drops arguments
to mysqld except those specified with --mysqld (if any).

• --valgrind[-all]

Run mysqltest and mysqld with valgrind. This and the
following --valgrind options require that the executables
have been built with valgrind support.

• --valgrind-mysqld

Run the mysqld server with valgrind.

• --valgrind-mysqltest

Run the mysqltest and mysql_client_test executables with
valgrind.

• --valgrind-option=str

Option to give valgrind. Replaces default option(s). Can be
specified more then once&.

• --valgrind-path=path

Path to the valgrind executable.

• --vardir=path

Specify the path where files generated during the test run
are stored. The default location is ./var. The environment
variable MYSQLTEST_VARDIR will be set to the path for this
directory, whether it has the default value or has been set
explicitly. This may be referred to in tests.

• --verbose

Give more verbose output regarding test execution. Use the
option twice to get even more output. Note that the output
generated within each test case is not affected.

• --verbose-restart

Write when and why servers are restarted between test cases.

• --view-protocol

Create a view to execute all non updating queries.

• --vs-config=config_val

Visual Studio configuration used to create executables
(default: MTR_VS_CONFIG environment variable) This option is
for Windows only.

• --wait-all

If --start or --start-dirty is used, wait for all servers to
exit before termination. Otherwise, it will terminate if one
(of several) servers is restarted.

• --warnings

Search the server log for errors or warning after each test
and report any suspicious ones; if any are found, the test
will be marked as failed. This is the default behavior, it
may be turned off with --nowarnings.
