Hai Dear ;

Please have these information

Black-box and white-box are test design methods. Black-box test design

treats the system as a "black-box", so it doesn't explicitly use

knowledge of the internal structure. Black-box test design is usually

described as focusing on testing functional requirements. Synonyms for

black-box include: behavioral, functional, opaque-box, and

closed-box. White-box test design allows one to peek inside the "box",

and it focuses specifically on using internal knowledge of the software

to guide the selection of test data. Synonyms for white-box include:

structural, glass-box and clear-box.

While black-box and white-box are terms that are still in popular use,

many people prefer the terms "behavioral" and "structural". Behavioral

test design is slightly different from black-box test design because

the use of internal knowledge isn't strictly forbidden, but it's still

discouraged. In practice, it hasn't proven useful to use a single test

design method. One has to use a mixture of different methods so that

they aren't hindered by the limitations of a particular one. Some call

this "gray-box" or "translucent-box" test design, but others wish we'd

stop talking about boxes altogether.

It is important to understand that these methods are used during the

test design phase, and their influence is hard to see in the tests once

they're implemented. Note that any level of testing (unit testing,

system testing, etc.) can use any test design methods. Unit testing is

usually associated with structural test design, but this is because

testers usually don't have well-defined requirements at the unit level

to validate.
