This directory contains test suites for the MariaDB server. To run
currently existing test cases, execute ./mysql-test-run in this directory.
Some tests are known to fail on some platforms or be otherwise unreliable.
In the file collections/smoke_test there is a list of tests that are
expected to be stable.
In general you do not have to have to do "make install", and you can have
a co-existing MariaDB installation, the tests will not conflict with it.
To run the tests in a source directory, you must do "make" first.
In Red Hat distributions, you should run the script as user "mysql".
The user is created with nologin shell, so the best bet is something like
# su -
# cd /usr/share/mysql-test
# su -s /bin/bash mysql -c ./mysql-test-run
This will use the installed MariaDB executables, but will run a private
copy of the server process (using data files within /usr/share/mysql-test),
so you need not start the mysqld service beforehand.
You can omit --skip-test-list option if you want to check whether
the listed failures occur for you.
To clean up afterwards, remove the created "var" subdirectory, e.g.
# su -s /bin/bash - mysql -c "rm -rf /usr/share/mysql-test/var"
If tests fail on your system, please read the following manual section
for instructions on how to report the problem:
https://mariadb.com/kb/en/reporting-bugs
If you want to use an already running MySQL server for specific tests,
use the --extern option to mysql-test-run. Please note that in this mode,
you are expected to provide names of the tests to run.
For example, here is the command to run the "alias" and "analyze" tests
with an external server:
# mysql-test-run --extern socket=/tmp/mysql.sock alias analyze
To match your setup, you might need to provide other relevant options.
With no test names on the command line, mysql-test-run will attempt
to execute the default set of tests, which will certainly fail, because
many tests cannot run with an external server (they need to control the
options with which the server is started, restart the server during
execution, etc.)
You can create your own test cases. To create a test case, create a new
file in the main subdirectory using a text editor. The file should have a .test
extension. For example:
# xemacs t/test_case_name.test
In the file, put a set of SQL statements that create some tables,
load test data, and run some queries to manipulate it.
Your test should begin by dropping the tables you are going to create and
end by dropping them again. This ensures that you can run the test over
and over again.
If you are using mysqltest commands in your test case, you should create
the result file as follows:
# mysql-test-run --record test_case_name
or
# mysqltest --record < t/test_case_name.test
If you only have a simple test case consisting of SQL statements and
comments, you can create the result file in one of the following ways:
# mysql-test-run --record test_case_name
# mysql test < t/test_case_name.test > r/test_case_name.result
# mysqltest --record --database test --result-file=r/test_case_name.result < t/test_case_name.test
When this is done, take a look at r/test_case_name.result.
If the result is incorrect, you have found a bug. In this case, you should
edit the test result to the correct results so that we can verify that
the bug is corrected in future releases.
If you want to submit your test case you can send it
to maria-developers@lists.launchpad.net or attach it to a bug report on
https://mariadb.org/jira/.
If the test case is really big or if it contains 'not public' data,
then put your .test file and .result file(s) into a tar.gz archive,
add a README that explains the problem, ftp the archive to
ftp://ftp.mariadb.org/private and submit a report to
https://mariadb.org/jira about it.
