Answer / manpreet singh dhawan

As we all know that in white box testing we have the access
to the code so in white box testing we can look at the code
before deciding the test data and also we can know the
potential area where the bugs can be found by looking at
the code

Answer / rajeshwar rao

WHITE BOX testing done by the developer
White box is nothing but coding.
White box testing is also called as glass box testing.
In these testing entire code of the system must be
available.
It is design based testing.
It is a structural testing.
In this white box testing developer must know the
structural knowledge.
In this white box testing some of these aspects will be
considered.
All indepent parts are executed at least once.
All logical dession are exercised both true are false.
All loops are executed at there boundaries.
All internal data structure will be exercised.

ADVANTAGES= 1. COVER common Ares.
2. Cover control structure.
3. Test an integrated the many modules.
For white box testing the developers must know the
structural knowledge. It focuses on the program part rather
then the funcnalitypart.

Answer / aravind

While doing a black box testing we will know the
requirement and we directly test the functionality. Here
there is a possibility of leaving certain input condition
(practically speaking exhaustive testing of the system is
not at all possible) which may lead to erroneous result.
This situation described above can be completely avoided by
doing an whitebox testing where we will have the access to
code and bring up a test scenario where the system will
fail and expose the hidden defect.

Answer / venkata suresh sandireddy

we prefer whte box tsting before blackbox testing becausr
of foloing advantages.

1. Performance:
There r diferent ways of logics to write a
program. Let us think if a program can be executed in 5sec,
3sc, 6sec we will definetly prefer the logic which will be
executed in 3sec. This can be done by trail and error
method and choose the best suitable logic related program
which results in time saving.

2. Time and cost:

3. Providing minimum guarantee to use the application.
