1. Which of the following are characteristics of testable software? Answer: d a. observability b. simplicity c. stability d. all of the above
2. The testing technique that requires devising test cases to demonstrate that each program function is operational is called? Answer: a a. black-box testing b. glass-box testing c. grey-box testing d. white-box testing
3. The testing technique that requires devising test cases to exercise the internal logic of a software module is called? Answer: d a. behavioral testing b. black-box testing c. grey-box testing d. white-box testing
4. The cyclomatic complexity metric provides the designer with information regarding the number of a. cycles in the program b. errors in the program
c. independent logic paths in the program
d. statements in the program Answer: c 5. Black-box testing attempts to find errors in which of the following categories Answer: d a. incorrect or missing functions b. interface errors c. performance errors d. all of the above e. none of the above
6. Testing OO class operations is made more difficult by Answer: d a. encapsulation
b. inheritance c. polymorphism d. both b and c
7. What is the differences between black-box testing and white-box testing?
Answer: Black-box testing involves testing the functionality of a software component without knowing the details of its internal logic. White-box testing involves testing the independent logic paths with full implementation knowledge.
8. What is equivalence partitioning as it applies to software testing? What is scenario-based testing? Answer: Equivalence partitioning technique divides the input domain into classes of equivalent data items. Test cases are derived from combinations of elements from each equivalence class. Exhaustive testing of all input domain values is not necessary. Scenario-based testing: The user tasks described in the use-cases are used to construct the test cases. It is used to uncover errors that occur when actors interact with the software (focus is on user behavior, not product behavior).
