Hi Refina,
       it is a good question. Black box testing isconducted 
in the external part of the application or check the 
funtionality of the application. So both the functional and 
blackbox testing are same.
If any comments please send mail to

Hai Refina,
            This is rajendra

Functional testing is part of system testing or blak box 
testing.

Actually functional testing means testing the functional 
behavior of the system by applying suitable inputs and 
observing o/p results.

normally functional testing is a part of b.b.testing. 
functional testing is testing the funtionality of an 
application. rather functional testing b.b.testing 
techniques are performance, user interface and security.

some wt 2 r same but black box testing means testing the 
application with out knowlegde on domain..
but functionality testing means testing the application in 
all possible values..

According to me the Black Box testing is a Technique which
has 2 Main Parts
1. Functional Testing - it involves the all the
Methodologies like BVA, EqP and all to verify the
Functionalities of system.

2. Non-Functional Testing - this is when we do the Load ,
Performance, Stress Testing.

hi every one,

Functional testing means checking the particular 
funtionality heavly with the help of giving suitable inputs.

Black Box testing means checking the whole funtionality 
without having any depth knowledge, so both how can come 
the same meaning?

come with discus abt this?

functional testing is a one part of black box testing

functional testing and block box testing both are 
same .because blockbox testing  is the process of testing 
the application using the testcase that are developed from 
req and design.in bb testingthe testor willnot have the 
knowledge of code.so it is also called as functional testing

functionl testing: testing the functionality of the 
application in depth where as blackbox testing is nothing 
but testing from the front end point of view against the 
requirements in black box testing their will be no code u 
should imagine a box in which u are giving input and output 
is cming out the box
