regression test master Makefile
bsd.regress.mk holds the standard routines
used by the source regression tests. Some variables and targets are for its
internal use only. The rest are documented here.
Since this file also includes
all of the usual OpenBSD Makefile variables may be
used to build the regression test programs.
- Build any dependencies required to carry out the current set of regression tests.
- Executes the regression targets defined in the Makefile. If a tests fails,
the line "FAILED" is printed to the standard output. By default,
execution stops after the first test failure and make
regressexits with a non-zero status.
- Runs an individual regression test. If the exit status of the program indicates an error or timeout, then a failure is logged, otherwise the test is marked as a success.
- If this variable is set, it contains a target that is executed after all regress targets.
- Targets which are expected to fail. Specifically: sometimes tests are added for features that should be supported eventually, but are somewhat complicated to fix right away.
- If this variable is set to anything but “no”, the
regresstarget will abort as soon as a test fails. Defaults to “yes” unless
- Points to the fully-qualified path of a file to which regression results
are appended. Defaults to /dev/null. If set to any
REGRESS_FAIL_EARLYdefaults to “no”.
- Targets for which root access is required to run the test. The
SUDOvariable should be used in the test parts that require root. See also
- If this variable is set, it contains a target that is executed before each regress target. Regress targets depend on this one to enforce setup.
- If this variable is set, it contains a target that is executed once before all regress targets. Regress targets depend on a stamp file generated during setup.
- If this variable is not empty, skip over all the regression tests which
have been marked as being 'slow' using the
- Targets which are unconditionally skipped.
- Targets which are defined as 'slow'. All of these tests can be skipped by
- Targets which are invoked to run the set of regression tests for this
Makefile. Defaults to
- Location of a command used to switch to root for certain test targets which require it. See doas(1).
Some variables are intended to be set at runtime in the environment or in mk.conf(5), but not in the regress Makefile itself.
If an individual test passes, make testname should return with an exit status of 0. If it fails, it should return with a non-zero exit status.
If a test cannot be executed because a package is not installed or
some environment variable is not set, make
testname should print "SKIPPED" to stdout
and exit with status 0. To skip everything, implement the
regress target with a command that prints
Some tests may require a special setup on the test machine that has to be done manually before testing. This requirement has to be documented in the Makefile or in a README file. The test should find out whether the setup exists before running and print "SKIPPED" and exit if it is missing.
Tests should not fail because an intended feature has not been implemented yet. To avoid such false failures, a test should show the reason, print "DISABLED" to stdout and exit with status 0.
Tests must be able to run with an obj
directory. In case the test is not linked to the build or the tester forgot
to run make
obj before, this
directory or symlink may not exist. Then the test should run anyway.
Tests are executed with make
regress, but running make
all or make should have the same
effect. Tests must be runnable by root, and may also succeed when run as a
regular user. Tests must not assume they have a controlling tty, to allow
them to be run by cron(8). An individual regress test may create a pseudo tty if it
Tests should use the binaries installed and the kernel running on
the local system. They may use environment variables to test alternative
binaries or remote kernels running on other machines. In some cases a test
may need binaries or libraries or object files to be present in
/usr/obj/ that exist only after
build was run in
/usr/src/. The test must not assume that they have
already been built, but should run make in the appropriate
source directory as a dependency. For missing generated source or header
files a target called make
generated is common. The
/usr/src/ tree can be found with a relative path or
Tests should generally not set or modify
MALLOC_OPTIONS unless it is testing specific
behaviour that depends on a particular flag or combination of flags. When
running tests, the appropriate sysctl (vm.malloc_conf) could be used
The regression system originally came from NetBSD, with many tests added by OpenBSD since. The current Makefile framework was written by Artur Grabowski and Marc Espie for OpenBSD 3.1.
