What is the need of Black Box Testing?
1) White box testing conducted by developer in a technical perception where as black box testing is conducted by test engineers with end-user perception.
2) Programmers will conduct white box testing in a positive perception whereas tester will conduct black box testing with a negative perception where there is a more chance of finding more defects
The more defects you identify results in a quality system.
3) White box testing will not cover non functional areas. As functional requirements are also very important for production system those are covered in black box testing.
4) The objective of white box testing is 100% coverage whereas the objective of black box testing is 100% customer business requirement coverage.
5) Black Box Testing = System Testing + User Accepting Testing which is called as requirement Based Testing (or) Specification Based Testing.
