Black-box testing - A testing approach whereby the program is considered as a complete entity and the internal structure is ignored. Test data are derived solely from the application’s specification. [The Art of Software Testing]

A) True
B) False
2
......... testing comes under black box testing.
A) Unit
B) Functional
C) System
D) Both B & C
3
Black box testing attempts to find errors in the external behavior of the code in the following categories.......
A) incorrect or missing functionality
B) interface errors
C) errors in data structures used by interface
D) behavior or performance errors
E) initialization and termination errors
F) All of above
4
It is best if the person who plans and executes black box tests is not the programmer of the code and does not know anything about the structure of the code.
A) True
B) False
5
The four specification-based or black-box techniques are:
A) Control flow graph
B) boundary value analysis
C) decision tables
D) state transition testing
E) equivalence partitioning
6

D) 2, 3, 4 or 5
7
What kind of errors are neglected by black-box testing and can be uncovered by white-box testing ?
A) behavioral errors
B) logic errors
C) performance errors
D) typographical errors
E) Synonymous errors
F) both b and d
8
You can develop a reasonably rigorous test by using certain black-box-oriented test-case-design methodologies
A) Equivalence partitioning
B) Boundary-value analysis
C) Cause-effect graphing
D) Error guessing
E) Statement coverage
F) Decision coverage

These two properties, although they appear to be similar, describe two distinct considerations. The first implies that each test case should invoke as many different input considerations as possible to minimize the total number of test cases necessary. The second implies that you should try to partition the input domain of a program into a finite number of equivalence classes such that you can reasonably assume (but, of course, not be absolutely sure) that a test of a representative value of each class is equivalent to a test of any other value.These two considerations form a black-box methodology known as ..........
A) Boundary Value Analysis
B) Equivalence Partitioning
C) Error Guessing
D) Cookie Testing
