Unit testing is one..which is nothing but testing a small
piece of code..
 it comes under white box testing..

Unit Testing is Testing the smallest Unit or block of code. 
Unit is defined as collection of segments.
It comes under Both White and Black Testing

I agree with BABA

Unit testing is Module wise testing of Application. As Unit 
testing is done by Programmer this testing is done for code 
testing i.e. White box testing. On the other side Manual 
testers do manual testing for it i.e. Black Box testing

Unit testing is usually done by programmers to test their 
code changes and it requires detail knowledge of the the 
internal program code.I think it comes under white box 
testing.

HI,
In the unit testing we take a small piece if coede and test
it apart from rest of the whole application.It comes under
both black box testing and white box testing.

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

it is a coding level testing done by the programmers using 
white box technique testings

Soon of the code is complited the developer will strat the 
unit testing. it is a method of microscale of testing.that 
means each line of the code will be tested to the rectify 
the error.unit testing comes under white box testing.it is 
done by the developers.
in these unit testing normaly comes some erros

incorrect initalijation.
mixed mode operationes.

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.
