X Y T T F F T F T F X^Y XvY NAND NOR (X and Y) (X or Y) Not (X and Y) Not (X or Y) Not X Not Y 2. (1 point) Matching. Select the letter of the phrase on the right that matches term on the left: Test Design ____ a. The process of evaluating test results and reporting to developers Test Automation ____ b. The process of imbedding test values in executable scripts. Test Execution ____ c. The process of designing input values that will effectively test software Test Evaluation ____ d. The process of running tests on the software and recording results 3. (2 points) What thing(s) is/are wrong with this pseudo-Java program (logic – NOT syntax)? /** * Find the “First Index” of the array entry with a value of one (1) * * @return the index of the first “1” in array X; or else return -1 if none found */ Procedure FirstOne (int[ ] x) Count = 0; for (int i = 0; i y y=y*x If (y = = 0) break else y=y*2 X=X+1 end end 5.

(1 point) According to Amman and Offutt, an external incorrect behavior in software is a software a. Bug b. Fault c. Software error d. Failure 7. (1 point) According to Amman and Offutt, a static defect in software is a software a. Bug b. Fault c. Error d. Failure 2 ITSM607 System Test and Verification. FINAL 3 8. (2 points) Agile development has changed the way we view testing. What are some positive views of testing on agile development and what are some negative views on testing on agile development. (Note I am asking you about Agile TESTING NOT Agile development). 9. (1 point) An Input Domain Model (IDM) represents the input space of a model under test in an abstract way (T or F) 10. (1 point) A test engineer describes the structure of the input domain in terms of input characteristics (T or F) 11. (1 point) The test engineer creates a single partition of the whole input domain in order to consolidate all characteristics of the test data into one big group. (T or F). 12. (1 point) The partitioning of the input domain into disjointed blocks is usually designed using knowledge of what the software is supposed to do. (T or F). 13. (2 points) Looking at the diagram below, write the section of code represented by this diagram. 1 X=1 2 X>Y X
