3. Which of the following statements BEST describes the difference between decision table testing and branch testing?

A.In decision table testing, the test cases are derived from the decision statements in the code. In branch testing, the test cases are derived from knowledge of the control flow of the test object.

B.In decision table testing, the test cases are derived from the specification that describes the business logic. In branch testing the test cases are based on anticipation of potential defects in the source code.

C.In decision table testing, the test cases are derived from knowledge of the control flow of the test object. In branch testing, test cases are derived from the specification that describes the business logic.

D.In decision table testing, the test cases are independent of how the software is implemented. In branch testing, test cases can be created only after the design or implementation of the code.

4. Customers of the TestWash car wash chain have cards with a record of the number of washes they have bought so far. The initial value is 0. After entering the car wash, the system increases the number on the card by one. This value represents the number of the current wash. Based on this number the system decides what discount the customer is entitled to.
For every tenth wash the system gives a 10% discount, and for every twentieth wash, the system gives a further 40% discount (i.e., a 50% discount in total).
Which of the following sets of input data (understood as the numbers of the current wash) achieves the highest equivalence partition coverage?

A.19, 20, 30

B.11, 12, 20

C.1, 10, 50

D.10, 29, 30, 31

Question 5 of 10

5. You are testing a form that verifies the correctness of the length of the password given as input. The form accepts a password with the correct length and rejects a password that is too short or too long. The password length is correct if it has between 6 and 12 characters inclusive. Otherwise, it is considered incorrect.
At first, the form is empty (password length = 0). You apply boundary value analysis to the “password length” variable.
Your set of test cases achieves 100% 2-value boundary value coverage. The team decided that due to the high risk of this component, test cases should be added to ensure 100% 3-value boundary value coverage.
Which additional password lengths should be tested to achieve this?

A.4, 5, 13, 14

B.7, 11

C.1, 5, 13

D.1, 4, 7, 11, 14

What is the decision table coverage achieved by these test cases?

A.40%

B.60%

C.80%

D.100%

A.Add, Remove, Add, Add, Add

B.Add, Add, Add, Add, Remove, Remove

C.Add, Add, Add, Remove, Remove

D.Add, Add, Add, Remove, Add

Question 8 of 10

8. You run two test cases, T1 and T2, on the same code. Test T1 achieved 40% statement coverage and test T2 achieved 65% statement coverage.
Which of the following sentences must be necessarily true?

A.The test suite composed with tests T1 and T2 achieves 105% statement coverage

B.There exists at least one statement that must have been executed by both T1 and T2

C.At least 5% of the statements in the code under test are non-executable

D.The test suite composed of tests T1 and T2 achieves full branch coverage

Question 9 of 10

9. Let the branch coverage metric be defined as BCov = (X / Y) * 100%.
What do X and Y represent in this formula?

A.X = number of decision outcomes exercised by the test cases Y = total number of decision outcomes in the code

B.X = number of conditional branches exercised by the test cases Y = total number of branches in the code

C.X = number of branches exercised by the test cases Y = total number of branches in the code

D.X = number of conditional branches exercised by the test cases Y = total number of decision outcomes in the code
