Answer / abdul.sameer

Unit Testing is purely a white box testing technique. Here
in unit testing we test the functionality of the small peace
of code developed by the developers.

Each and every developers check there code (Unit
testing) to confirm themselves that they work done is
working fine.
In unit testing we check for code coverage testing which
further consists of loop coverage, statement coverage, path
coverage, there functionality and mutation testing. is there
any unwanted or repeatable variable assigned or not.

for each unit test the developers test the exact
functionality and is not realted to any black box technique.

it is purely a white box testing.

Answer / sowmya

Hi
Unit testing is testing individual module fo an
application.it is done by developers.it comes under white
box testing.In black box testing we test the functinality
or behavior of an application.we dont have the internal
knowledge of the application.where as in white box testing
basic path coverage,loops and funtions written in coding

Answer / ashok

Design document was basedline corresponding programmes can start with coding by write programmer and then programmer can test each program completeness and correcteness called as unit testing

During this unit testing programmer can follow four white box techniques

1)based path coverage
2)control structure coverage
3)program techniques coverage
4)mutation coverage

Answer / sylesh

I think it depends on how you define the so called 'unit'.
Consider a situation where you wrote an application with
just one functionality, which is implemented in precisely
one function. Assume this function contains 3 logical
blocks of code, say an if..else, a for loop and then
another block of statements.

If we are to say that a white box testing has been done on
that code, we should have tested each of these different
blocks of statements, ensure coverage by carrying out
various and as many tests required by inputting as many
varied parameters to ensure that the execution of code has
been tested through each of the lines / blocks of code.

Same time, the programmer would have tested the function
just by passing the input parameters as specified / assumed
from the functionality of the application and would have
verified whether the output has come right.

So if we consider the unit under consideration to be a
function then I think the so called unit test in that case
should be considered more close to black box where as if
the programmer has catered for complete coverage
considering each and every line of code, it should be
considered white box.

Obviously white box testing is more fail safe but sometimes
programmers end up writing unit test cases just for public
functions in which case I prefer to say it is close to
black box.
