1. Question 101 · 138 in bank

   Which of the following statements is CORRECT about White-box testing?

   • AWhite-box testing helps find defects because they can be used to measure statement coverage
   • BWhite-box testing helps find defects because it focuses on defects rather than failures
   • CWhite-box testing helps find defects even when specifications are vague because it takes into account the code
   • DWhite-box testing helps find defects because it provides for requirements-based coverage

3. Question 103 · 138 in bank

   Which ONE of the following options MOST ACCURATELY describes statement testing?

   • AIn statement testing, the coverage items are control flow transfers between branches. The aim is to design test cases to exercise branches in the code until an acceptable level of coverage is achieved, expressed as a percentage.
   • BIn statement testing, the coverage items are decisions and statements. The aim is to design test cases that exercise statements in the code until an acceptable level of coverage is achieved, expressed as a percentage.
   • CIn statement testing, the coverage items are branches, and the aim is to design test cases to exercise branches in the code until an acceptable level of coverage is achieved, expressed as a percentage.
   • DIn statement testing, the coverage items are executable statements. The aim is to design test cases that exercise statements in the code until an acceptable level of coverage is achieved, expressed as a percentage.

4. Question 104 · 138 in bank

   Scenario “Happy Tomatoes” An intelligent application for agricultural use incorporates temperature sensors located at different points of an enclosure. The sensors measure and record the temperature at regular intervals and extract the statistical values for these measurements. These values include the average daily temperature. A new variety of tomatoes is currently being grown and the “World Organization for Happy Tomatoes” has established temperature ranges related to vegetative development. When the system establishes that the average temperature is within a specific range, it emits a value that will be used to monitor and control the crop.

   

   Using the Boundary Value Analysis technique (in its two-point variant), identify the set of input values that provides the HIGHEST coverage.

   • A{7, 8, 21, 22, 29, 30}
   • B{7, 8, 22, 23, 29, 30}
   • C{6, 7, 8, 21, 22, 29, 31}
   • D{6, 7, 21, 22, 29, 30}

9. Question 109 · 138 in bank

   User Story: As a member of the “Agnotoly” association, I want to be able to pay the association's dues through an automatic payment method so that I can forget about payment deadlines. Acceptance Criteria: • The member can only pay with “Agnosis Master” credit card. • The member must register their cell phone number. • The member must register the credit card in the association's payment system. • The member must select one of the following credit card payment methods: monthly or annual. • For the payment system to proceed with the transaction, the member must accept the terms and conditions applicable to the selected payment method (monthly or annual payment). • If the member accepts the terms and conditions, the payment system sends a message to the member's mobile/cell phone with a one-time password and prompts the member to enter the one-time password. • The payment method is registered in the association's payment system once the one-time key sent by the payment system is verified. • Once the payment method is registered, the association's payment system will charge the member on the first business day of the following month. Remark: The payment method registration is a transactional process; therefore, if the acceptance criteria 1 through 7 are not met, the payment system will revert to its previous state and will not maintain any information that may have been entered. In the test cycle that has just ended, the following objectives have been achieved: • Members of the association have been able to pay association dues with the credit card. • Dues payments have been made on a monthly basis and for more than a year since the initial payment. Which ONE of the following options identifies the acceptance criteria that has NOT been fully covered during the above test cycle?

   • AAcceptance criteria 8 has not been fully covered during the above test cycle.
   • BAcceptance criteria 4 has not been fully covered during the above test cycle.
   • CAll acceptance criteria have been fully covered during the above test cycle.
   • DAcceptance criteria 6 has not been fully covered during the above test cycle.
