     tests - introduction to the FreeBSD Test Suite

     The FreeBSD Test Suite provides a collection of automated tests for two
     major purposes.  On one hand, the test suite aids developers to detect
     bugs and regressions when they modify the source tree.  On the other
     hand, it allows end users (and, in particular, system administrators) to
     verify that fresh installations of the FreeBSD operating system behave
     correctly on their hardware platform and also to ensure that the system
     does not suffer from regressions during regular operation and

     The FreeBSD Test Suite can be found in the /usr/tests hierarchy.

     This manual page describes how to run the test suite and how to configure
     some of its optional features.

   Installing the test suite
     The test suite is not yet installed by default as part of FreeBSD, but
     this is bound to change during the development of FreeBSD 11.0.

     If the /usr/tests directory is missing, then you will have to enable the
     build of the test suite, rebuild your system and install the results.
     You can do so by setting `WITH_TESTS=yes' in your /etc/src.conf file (see
     src.conf(5) for details) and rebuilding the system as described in

   When to run the tests?
     Before diving into the details of how to run the test suite, here are
     some scenarios in which you should run it:

              After a fresh installation of FreeBSD to ensure that the system
               works correctly on your hardware platform.

              After an upgrade of FreeBSD to a different version to ensure
               that the new code works well on your hardware platform and that
               the upgrade did not introduce regressions in your

              After modifying the source tree to detect any new bugs and/or

              Periodically, maybe from a cron(8) job, to ensure that any
               changes to the system (such as the installation of third-party
               packages or manual modifications to configuration files) do not
               introduce unexpected failures.

   Running the tests
     First, you will need to install the `devel/kyua' package from ports(7).
     Then use the following command to run the whole test suite:

           $ kyua test -k /usr/tests/Kyuafile

     The above will iterate through all test programs in /usr/tests
     recursively, execute them, store their results and debugging data in
     Kyua's database (by default in ~/.kyua/store.db), and print a summary of
     the results.  This summary includes a brief count of all total tests run
     and how many of them failed.

     It is possible to restrict which tests to run by providing their names in
     the command line.  For example, this would execute the tests for the
     cp(1) and cut(1) utilities:

           $ kyua test -k /usr/tests/Kyuafile bin/cp usr.bin/cut

   Obtaining reports of the tests execution
     Additional information about the test results can be retrieved by using
     Kyua's various reporting commands.  For example, the following would
     print a plain-text report of the executed tests and show which ones

           $ kyua report

     This example would generate an HTML report ready to be published on a web

           $ kyua report-html --output ~/public_html/tests

     For further details on the command-line interface of Kyua, please refer
     to its manual page kyua(1).

   Configuring the tests
     Some test cases in the FreeBSD Test Suite require manual configuration by
     the administrator before they can be run.  Unless certain properties are
     defined, the tests that require them will be skipped.

     Test suites are configured by defining their configuration variables in
     /usr/local/etc/kyua/kyua.conf.  The format of this file is detailed in

     The following configuration variables are available in the FreeBSD Test

     allow_devfs_side_effects   If defined, enables tests that may destroy and
                                recreate semipermanent device nodes, like disk
                                devices.  Without this variable, tests may
                                still create and destroy devices nodes that
                                are normally transient, like /dev/tap* and
                                /dev/pts*, as long as they clean them up
                                afterwards.  However, tests that require this
                                variable have a relaxed cleanup requirement;
                                they must recreate any devices that they
                                destroyed, but not necessarily with the same

     allow_sysctl_side_effects  Enables tests that change globally significant
                                sysctl(8) variables.  The tests will undo any
                                changes in their cleanup phases.

     disks                      Must be set to a space delimited list of disk
                                device nodes.  Tests that need destructive
                                access to disks must use these devices.  Tests
                                are not required to preserve any data present
                                on these disks.

     fibs                       Must be set to a space delimited list of FIBs
                                (routing tables).  Tests that need to modify a
                                routing table may use any of these.  Tests
                                will cleanup any new routes that they create.

   What to do if something fails?
     If there is any failure during the execution of the test suite, please
     consider reporting it to the FreeBSD developers so that the failure can
     be analyzed and fixed.  To do so, either send a message to the
     appropriate mailing list or file a problem report.  For more details

     The FreeBSD Test Suite first appeared in FreeBSD 10.1.

     The tests manual page first appeared in NetBSD 6.0 and was later ported
     to FreeBSD 10.1.
