White Box Testing:Means testing the application with 
coding /programming knowledge.That means the tester has to 
correct the code also.

Black box testing:testing the application without 
coding /programming knowledge that means the tester doesn't 
require coding knowledge.Just he examines the appliaction 
external fucntional beheaviour and GUI features.

White box testing is done by the Developers. This requires
knowledge of the internal coding of the software. 

Black box testing is done by the professional testing team.
This does not require knowledge of internal coding of the
application. Testing the application against the
functionality of the application with out the knowledge of
internal coding of the software.

(1)Generally black box testing will begin early in the 
   software development i.e. in requirement gathering 
   phase itself. 
   But for white box testing approach one has to wait for  
   the designing has to complete.

2)We can use black testing strategy almost any size either 
  it may be small or large. 
  But white box testing will be effective only for small   
  lines of codes or piece of codes.

3)In white box testing we can not test Performance of the 
  application.
  But in Black box testing we can do it.


4 )In general we have to write large quantity of test 
   cases for whitebox. 
   But in black box its a selcection of sample test cases.

black box testing is mainly done by developer because in
which you need  good knowledge of coding part but on the
other hand white box testing is done by any member of
testing team.In which you do not require any knowledge of
the coding part.you have to check functionality of each and
every part and also every feature of GUI.

In Black Box testing, maintainability is hard, as when the User Interface constantly change the inputs also will have to change. In White Box Testing maintainability will be much easier than Black Box test as it deals with the underline codes, and a user Interface will not affect maintainability of the program.
