Plug in a client and watch !

Do you mean test performance or test functionality, the two are VERY
To test functionality, unplug the network cable on a client and plug
it back in. You should see the client do a dhcp-request and the
server respond with an ack. Assuming that the client got an address
under step 1 (dhcp-discover, dhcp-offer, dhcp-request, dhcp-ack) then
you have tested the main functions.
Testing DDNS is really just a matter of checking that the right DNS
records get added.
If you really mean performance testing (aka stress testing), check
the mail archives as there have been a few mentions of tools to
stress test dhcp servers.
>3. What all tools will be required to perform the testing?
Basic testing - just the normal unix tools (cat, tail, ...) If you
meed to diagnose stuff because something isn't working that a packet
sniffer (I use Wireshark) is very useful.
>4. How much time it will take to perform all the test cases?
Basic cases, about 5 mins. Beyond that depends on how complex your
setup is - if you have lots of special cases/classes/etc then it will
take longer to work your way through those.
