Question 2
Which of the following is true about def-clear paths with respect to a variable v?
The variable v is not defined along the path.
The variable v is not given another value along the path
The variable v is defined once but is not used along the path.
The variable v is defined and used along the path.
Show answer
Correct answer
The variable v is not given another value along the path
Question 3
A test case is said to have passed when which of the following holds?
The actual output is different from expected output but there is no error.
The actual output is the same as the expected output.
The software produces an output successfully upon giving an input
There is a message that there is no error from the program.
Show answer
Correct answer
The actual output is the same as the expected output.
Question 4
Which of the following represents the correct order of subsumption amongst data-flow coverage criteria in graphs? Read the symbol → below as “subsumes”.
All-defs-coverage → all-du-paths-coverage → all-uses-coverage.
All-defs-coverage → all-uses-coverage → all-du-paths-coverage.
All-du-paths-coverage → all-uses-coverage → all-defs-coverage.
All-du-paths-coverage → all-defs-coverage → all-uses-coverage
Show answer
Correct answer
All-du-paths-coverage → all-uses-coverage → all-defs-coverage.

Question 6
For a tester to observe an error or a fault in a particular location of a program, which of the following should be true together?
The location of the program should be reachable by the test case given by thetester.
The state of the program must be incorrect at that location of the program.
The final state of the program should be incorrect.
The tester should see the error in the program.
Show answer
Correct answers
The location of the program should be reachable by the test case given by thetester.
The state of the program must be incorrect at that location of the program.
The final state of the program should be incorrect.

a=0, b=1
Show answer
Correct answers
a=5, b=7
a=0, b=1
Question 8
Consider that a coverage criteria C1 subsumes coverage criteria C2. Also that there exists a test set T1 that satisfies C1 on some code base B and another test set T2 that satisfies C2 on the same code base B.
Select the statements that are correct for the above scenario.
T1 will necessarily satisfy C2.
T2 wil necessarily satisfy C1
If T2 exposes some fault in B implies that T1 will also be able to expose thesame fault.
None of these
Show answer
Correct answer
T2 wil necessarily satisfy C1
