Answer / vinay rana

In white box testing,we do inspection of code(means this
type of testing is referred to internal structure of
software or system)
It may be :-

code coverage:-execute each statement atleast once
branch coverage:used for control statements(most
prefferable)

Black box testing is used to check the extrenal behaviour
of the system irrespective to internal structure or code

Answer / ajay

White box testing is done by the developers only.. in this
case they go for code testing means internal structure of
the application.

Black box testing is done by the testing team.. in this we
do tesiting on the functionality part by applying valid and
invalid inputs.......

The person who has domain knowledge on which he is working
can perform both White box and Black box testing..

Hope u understood clearly

any douts u can mail me to ajay.thomala@gmail.com

Answer / rudraneel

First of all there are two test design techniques...one is
black box and another is white box...These testing
techniques are totally different from each other....the
white box is for unit and integration and black box is uesd
for system and user acceptance testing...by combininf these
total testing of a product or application can be
achieved...so that's why both are necessary because they
have significance advantages different to each other.

Answer / sree

White box testing:
this will be done Developer, where we ll check the internal
structure(code) of the application.

Black Box tesing:
This will done by the tester, where we ll check the
functionality of the application.

So y we ll go for White box testing means..
there may be some leakages in Black box testing as we are
just ches=cking in the UI,so we ll go for White box
