Question 1 of 10

1. Given the following descriptions of review activities:

Detected anomalies are deliberated upon, and determinations are reached regarding their status, ownership, and any further steps needed
Issues are recorded, and any needed updates are addressed prior to the acceptance of the work product
Reviewers employ techniques to come up with suggestions and questions about the work product and to spot anomalies
The objective of the review and its schedule are established to ensure a focused and efficient review
Participants are provided with access to the item being reviewed

Which of the following is the CORRECT sequence in the review process of the activities that correspond to the descriptions?

A.4 – 3 – 5 – 2 – 1

B.4 – 5 – 3 – 1 – 2

C.5 – 4 – 1 – 3 – 2

3. You perform system testing of an e-commerce web application and are provided with the following requirement:

REQ 05-017. If the total cost of purchases exceeds $100, the customer gets a 5% discount on subsequent purchases. Otherwise, the customer does not receive a discount.

Which test techniques will be MOST helpful in designing test cases based on this requirement?

A.White-box test techniques

B.Black-box test techniques

C.Experience-based test techniques

D.Risk-based test techniques

Question 4 of 10

4. The system for selling cinema tickets calculates the discount type based on the client’s birth year (BY) and on the current year (CY) as follows:

Let D be the difference between CY and BY, that is, D = CY – BY

If D < 0 then print the error message “birth year cannot be greater than current year”
If 0 ≤ D < 18 then apply the student discount
If 18 ≤ D < 65 then apply no discount
If D ≥ 65 then apply the pensioner discount

Your test suite already contains two test cases:

BY = 1990, CY = 2020, expected result: no discount
BY = 2030, CY = 2029, expected result: print the error message

Which of the following test data sets should be added to achieve full valid equivalence partitioning coverage for the discount type?
Select TWO options.

A.BY = 2001, CY = 2065

B.BY = 1900, CY = 1965

C.BY = 1965, CY = 1900

D.BY = 2011, CY = 2029

E.BY = 2000, CY = 2000

5. You are testing a temperature control system for a horticultural cold storage facility. The system receives the temperature (in full degrees Celsius) as the input. If the temperature is between 0 and 2 degrees inclusive, the system displays the message “temperature OK”. For lower temperatures, the system displays the message "temperature too low" and for higher temperatures it displays the message “temperature too high”.
Using two-value boundary value analysis, which of the following sets of test inputs provides the highest level of boundary value coverage?

A.–1, 3

B.0, 2

C.–1, 0, 2, 3

D.–2, 0, 2, 4

Question 5 of 10

Question 6 of 10

You are designing test cases based on the following decision table.

So far you have designed the following test cases:

TC1: 19-year-old, unregistered man with no experience; expected result: category A
TC2: 65-year-old, unregistered woman with 5 years of experience; expected result: category B
TC3: 66-year-old, registered man with no experience; expected result: category C
TC4: 65-year-old, registered woman with 4 years of experience; expected result: category D

Which of the following test cases, when added to the existing set of test cases, will increase the decision table coverage?

A.66-year-old, unregistered man with no experience; expected result: category B

B.55-year-old, unregistered woman with 2 years of experience; expected result: category A

C.19-year-old, registered woman with 5 years of experience; expected result: category D

D.No additional test case can increase the already achieved decision table coverage

Question 7 of 10

You are applying state transition testing to the hotel room reservation system modeled by the following state transition table, with 4 states and 5 different events:

Assuming all test cases start in the ‘Requesting’ state, which of the following test cases, represented as sequences of events, achieves the highest valid transitions coverage?

A.NotAvailable, Available, ChangeRoom, NotAvailable, Cancel

B.Available, ChangeRoom, NotAvailable, Available, Pay

C.Available, ChangeRoom, Available, ChangeRoom, NotAvailable

D.NotAvailable, Cancel, ChangeRoom, Available, Pay

Question 8 of 10

8. Your test suite S for a program P achieves 100% statement coverage. It consists of three test cases, each of which achieves 50% statement coverage.
Which of the following statements is CORRECT?

A.Executing S will cause all possible failures in P

B.S achieves 100% branch coverage for P

C.Every executable statement in P containing a defect has been run at least once during the execution of S

D.After removing one test case from S, the remaining two test cases will still achieve 100% statement coverage

Question 8 of 10

Question 9 of 10

9. Why does white-box testing facilitate defect detection even when the software specification is vague, outdated or incomplete?

A.Test cases are designed based on the structure of the test object rather than the specification

B.For each white-box test technique the coverage can be well-defined and easily measured

C.White-box test techniques are very well designed to detect omissions in the requirements

D.White-box test techniques can be used in both static testing and dynamic testing

Question 9 of 10

Question 10 of 10

10. Which of the following is NOT anticipated by the tester while applying error guessing?

A.The developer misunderstood the formula in the user story for calculating the interest

B.The developer wrote “FA = A*(1+IR^N)” instead of “FA = A*(1+IR)^N” in the source code

C.The developer missed the seminar on new compound interest rate legislation

D.The accuracy of the interest calculated by the system is not precise enough
