What is White box & Black Box Testing?..

Answer / sj1234

White Box Testing White box testing (a.k.a. clear box
testing, glass box testing or structural testing) uses an
internal perspective of the system to design test cases
based on internal structure. It requires programming skills
to identify all paths through the software. The tester
chooses test case inputs to exercise paths through the code
and determines the appropriate outputs. In electrical
hardware, testing every node in a circuit may be probed and
measured; an example is in-circuit testing (ICT).

Black Box Testing alao known as functional testing.
software testing technique whereby the internal workings of
the item being tested are not known by the tester. For
example, in a black box test on a software design the
tester only knows the inputs and what the expected outcomes
should be and not how the program arrives at those outputs.
The tester does not ever examine the programming code and
does not need any further knowledge of the program other
than its specifications.
