what is the difference b/w functional testing and system
testing?

Answer Posted / prasanna

From my point of view, system testing is broadly classified
into functional and non-func. testing. hence Functional
Testing is a part of System Testing.

In system testing, testers test the product typically like
the end-user.Every single Interface,module and even minute
details have to be tested in this System Testing.

Functional Testing aims at testing the various
functionalities of the product being tested.These
functionalities include load,volume,stress,
scalability,security,performance,etc.
