The test system that is included in Unix source and binary distributions makes it possible for users and developers to perform regression tests on the MySQL code. These tests can be run on Unix.
You can also write your own test cases. For information about the MySQL Test Framework, including system requirements, see the manual available at https://dev.mysql.com/doc/mysqltest/2.0/en/.
The current set of test cases does not test everything in MySQL, but it should catch most obvious bugs in the SQL processing code, operating system or library issues, and is quite thorough in testing replication. Our goal is to have the tests cover 100% of the code. We welcome contributions to our test suite. You may especially want to contribute tests that examine the functionality critical to your system because this ensures that all future MySQL releases work well with your applications.
The test system consists of a test language interpreter
(mysqltest), a Perl script to run all tests
(mysql-test-run.pl), the actual test cases
written in a special test language, and their expected results.
To run the test suite on your system after a build, type
make test from the source root directory, or
change location to the
and type ./mysql-test-run.pl. If you have
installed a binary distribution, change location to the
mysql-test directory under the installation
root directory (for example,
/usr/local/mysql/mysql-test), and run
./mysql-test-run.pl. All tests should
succeed. If any do not, feel free to try to find out why and
report the problem if it indicates a bug in MySQL. See
Section 1.7, “How to Report Bugs or Problems”.
If one test fails, you should run
mysql-test-run.pl with the
--force option to check whether any other tests
If you have a copy of mysqld running on the
machine where you want to run the test suite, you do not have to
stop it, as long as it is not using ports
9307. If either of
those ports is taken, you should set the
MTR_BUILD_THREAD environment variable to an
appropriate value, and the test suite will use a different set
of ports for master, slave, and NDB). For example:
shell> export MTR_BUILD_THREAD=31 shell> ./mysql-test-run.pl [options] [test_name]
mysql-test directory, you can run an
individual test case with ./mysql-test-run.pl
If you have a question about the test suite, or have a test case
to contribute, send an email message to the MySQL
internals mailing list. See
Section 1.6.2, “MySQL Mailing Lists”.
