Equivalence partitioning is a _____ testing method that divides the input domain of a program into classes of data from which test cases can be derived.
Answer B Black box
Equivalence partitioning
Divides the input domain into classes of data
1.If an input condition specifies a range, define one valid and two invalid equivalence classes
2.If an input condition requires a specific value, define one valid and two invalid equivalence classes.
3.If an input condition specifies a member of a set, define one valid and one invalid equivalence class.
4.If an input condition is Boolean, define one valid and one invalid class.
If one test case in a class detects an error, all test cases in same class will detect that error.
If one test case in a class fails to detect an error, all test cases in same class will fail to detect that error.
