7 / 40

7. You are testing a PIN validator, which accepts valid PINs and rejects invalid PINs. A PIN is a sequence of digits. A PIN is valid if it consists of four digits, at least two of which are different. You have identified the following valid equivalence partitions:

Variable: PIN code length

• The partition “length correct” - four-digit PINs
• The partition “length incorrect” - PINs with length other than 4

Variable: Number of different digits

• The partition “number of different digits correct” - PINs with at least two different digits
• The partition “number of different digits incorrect” - PINs with all digits being the same

Which of the following is a MINIMUM set of input test data that covers all identified equivalence partitions?

Select ONE option.

16. 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?

Select ONE option.

17 / 40

17. You work as a tester in a project on a mobile application for food ordering for one of your clients. The client sent you a list of requirements. One of them, with high priority, says

“The order must be processed in less than 10 seconds in 95% of the cases”.

You created a set of test cases in which a number of random orders were made, the processing time measured, and the test results were checked against the requirements.

What test type did you perform?

Select ONE option.

18 / 40

18. You have been assigned as a tester to a team producing a new system incrementally. You have noticed that no changes have been made to the existing regression test cases for several iterations and no new regression defects were identified. Your manager is happy, but you are not. Which testing principle explains your skepticism?

Select ONE option.

19 / 40

19. Which of the following statements BEST describes the acceptance test-driven development (ATDD) approach?

Select ONE option.

20 / 40

20. Which of the following BEST define EXIT criteria in a testing project?

Select TWO options.

21 / 40

21. Which of the following is NOT true for white-box testing?

Select ONE option.

22 / 40

22. You are testing a web application that allows users to SEARCH for products, VIEW product details, ADD products to a shopping cart, and place an ORDER.
You have prepared the following five test cases, which you want to execute according to their priorities:

TC1: SEARCH product A Priority: medium

TC2: VIEW product A details Priority: low

TC3: ADD product B to a shopping cart Priority: medium

TC4: ADD product C to a shopping cart Priority: high

TC5: place an ORDER Priority: high

You also identified the following logical dependencies between test cases:

• SEARCH functionality must be tested before VIEW functionality can be tested, as product details rely on search functionality.
• VIEW functionality must be tested before ADD functionality, as adding products relies on the availability of accurate product details.
• ADD functionality must be tested before ORDER functionality, as placing an order relies on the availability of accurate shopping cart information.

Which test case should be executed as the fourth one?

Select ONE option.

23 / 40

23. A wine storage system uses a control device that measures the wine cell temperature T (measured in °C, rounded to the nearest degree) and alarms the user if it deviates from the optimal value of 12, according to the following rules:

• if T = 12, the system says, “optimal temperature”

• if T < 12, the system says, “temperature is too low!”

• if T > 12, the system says, “temperature is too high!”

You want to use the 3-point boundary value analysis (BVA) to verify the behavior of the control device. A test input is a temperature in °C provided by the device.

What is the MINIMAL set of test inputs that achieves 100% of the desired coverage?

Select ONE option.
