Equivalence partitioning is a __________ method that divides the input domain of a program into classes of data from which test cases can be derived.

  • A.White-box testing
  • B.Black-box testing
  • C.Orthogonal array testing
  • D.Stress testing

Answer: B

Equivalence partitioning is a black-box testing method that divides the input domain of a program into classes of data from which test cases can be derived. A class is a set of inputs that the program should treat in the same way, so one representative of each class is tested.

White-box testing works from the internal structure of the code, orthogonal array testing is a technique for choosing combinations of inputs, and stress testing pushes the system beyond its normal load. The method that works from the input classes alone is black-box testing, which is (B).
