what is black box testing

Answer Posted / preethi

Also known as functional testing. Asoftware 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
