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

rpzrecurse/ Another set of RPZ tests to check recursion behavior

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.
