what are the testing tools available to check the NS2 project.
I have completed my network security project in network simulator for documentation i should submit testing report also. so i need to know any testing tools available for NS2 projects..

Well, the fact that you have been able to run your files, etc.
is actually the best "Real world test".

The first test, you did, was "./validation", which also can be run
with the command 'make test'. ( cd ns-allinone-2.xx/ns-2.xx/ && make test ).

You can show the last lines of 'validation' as documentation.
( Or use all 100,000 lines.)

oh fine thanks is their any other way to show the testing strategy. bcoz here they are expecting to show the testing as unit testing, integration testing, system testing etc. so is their any particular options to show these testing..

None I know about. Suggest : Use Google to look for suggestions.
Quite easy : When no hits on page 1 or 2 : There is usually nothing.
( Google .. unit testing ns2 .. )

"unit testing" : No units, as we simulate everything.

"integration testing" : At least no integration with the Linux OS,
when we are using a standalone application = allinone = ns-allinone-2.xx.

"system testing" : That's a broad term, can mean anything.
NS-allinone-2.xx system ? Or ?


Other considerations : Present the complete 'make test' = validation,
and look for something, you can put a headline on.
Besides that, I have never read about any occasions,
where the instructor asked for any tests.

oh fine thanks for your valuable suggestion.
