hello friends,
here is the question is diff between functional and system
testing right?
all answers are right..but u are getting confused.
in functional testing we are just testing the
functionality...no maters what testing technique being used.
system testing include complete testing process,smoke,
sanity then regression, then UAT.

Answer / muralidhar kotti
In System testing the objective is to make sure that the
system is working as defined in the base line document and
its interfaces with other upstream and down stream systems.
where as in functional testing we will be testing the
functionality is appropriate or not. e.g: interest
calculation, EMI calculation etc

Answer / swetha
System testing : Testing is done by QA is Sysytem testing,Testing of fully complete integrated s/w i.e functional requirements particularly satisfies all client requiremnets..under sysytem testing we follow many types of testing.
1.exploratory
2.smoke
3.functional
4.sanity
5.retest
6.regression
7.browser ,cross broeser compatability,security
8.performance
9.high availability
then UAT
Alpha,Beta
...
Functional testing :testing the s/w indepth& detail
for ex: www.google.com
1s you enter valid data in username,pw..the features /functions of gamil..inbox,composemail,spam,circle....will tested here deply means how they are working and working propely or not by giving valid,invali data ...mets the client require or not.
This is a part of sysytem testing..if any error found report to developers team and 1s they fixed you will test retest ang regression...and so on..

Answer / deepak
Readers ,
I give you all examples :
I got one process which has 3 programs in it , say i use
Program 1 > inputs to > Program 2 > inputs to > program 3 .
Functional testing :I will test functionality of Program 1,
2 and 3 each seperately.
System Testing : I test how Program 1 inputs to Program 2
then Program 2 to Program 3 and finally my motive is
achieved performing all above.So in this i test the
functionality of system as a whole.
we might use different TECHNIQUES for both Func. and System
testings.
Hope i am clear with my response and make sense.
Thanks
Deepak

Answer / chabs
Functional testing is testing the individual components(,its
features) whether they work as per the requirement or not.
Ex: To test that Login textbox should accept only
characters, and the characters should be between 8-12 etc...
System testing is an end to end testing where the testing
environment is like the production environment.
While we do system testing we wont be bothered about testing
the components individually(functional testing) or whether
integrating the components works or not(integration testing)
because before we start system testing functional and
integration testing will be usually over.
Ex: Say, the customer wants a bank application which charges
the user 10% interest plus the activation charge the first
month,and charges only the interest from the 2nd and
succeeding months for which he has taken loan...
System testing for this includes testing for the first month
whether its charging 10% interest plus activation amt. and
no activation amt from the next month(by advancing the
database/server time)
Correct me if am wrong... comments r welcome.

Answer / sachin
Thanks Muralidhar for this informative answer
But still I have an issue
I am dividing your answer into parts.. you said
a) “in system testing Objective is to make sure that the
system is working as defined in the base line document” and
b) for functional testing we will be testing the
functionality is appropriate or not…
But again.for part b.. For testing functionality we take
help of baseline document..and again it is similar to part
a which you have explained..
that means by your explanation also..the final result is
Functional testing is a part of system testing.. so ..
sorry for asking the same question again .. please tell
me “ Functional testing is a part of system testing “
This statement is right or wrong
