This is a simple test environment for running bind9 system tests
involving multiple name servers.
There are multiple test suites, each in a separate subdirectory and
involving a different DNS setup. They are:
dnssec/ DNSSEC tests
forward/ Forwarding tests
glue/ Glue handling tests
limits/ Tests of handling of large data (close to server limits)
lwresd/ Tests of the lightweight resolver library and daemon
notify/ More NOTIFY tests
nsupdate/ Dynamic update and IXFR tests
resolver/ Regression tests for resolver bugs that have been fixed
(not a complete resolver test suite)
rrl/ query rate limiting
rpz/ Tests of response policy zone (RPZ) rewriting
stub/ Tests of stub zone functionality
unknown/ Unknown type and class tests
upforwd/ Update forwarding tests
views/ Tests of the "views" statement
xfer/ Zone transfer tests
xferquota/ Zone transfer quota tests
Typically each test suite sets up 2-5 name servers and then performs
one or more tests against them. Within the test suite subdirectory,
each name server has a separate subdirectory containing its
configuration data. By convention, these subdirectories are named
"ns1", "ns2", etc.
The tests are completely self-contained and do not require access to
the real DNS. Generally, one of the test servers (ns1) is set up as a
root name server and is listed in the hints file of the others.
To enable all servers to run on the same machine, they bind to
separate virtual IP address on the loopback interface. ns1 runs on
10.53.0.1, ns2 on 10.53.0.2, etc. Before running any tests, you must
set up these addresses by running "ifconfig.sh up" as root.
Mac OS X:
If you wish to make the interfaces survive across reboots
copy org.isc.bind.system and org.isc.bind.system to
/Library/LaunchDaemons then run
"launchctl load /Library/LaunchDaemons/org.isc.bind.system.plist" as
root.
The servers use port 5300 instead of the usual port 53, so they can be
run without root privileges once the interfaces have been set up.
The tests can be run individually like this:
sh run.sh xfer
sh run.sh notify
etc.
To run all the tests, just type "make test".
When running system tests, named and lwresd can be run under
Valgrind. The output from Valgrind are sent to per-process files that
can be reviewed after the test has completed. To enable this, set the
USE_VALGRIND environment variable to "helgrind" to run the Helgrind
tool, or any other value to run the Memcheck tool. To use "helgrind"
effectively, build BIND with --disable-atomic.
