Update to the Maintainability requirements during the development phase

NEW QUESTION 37
Which of the following statements about Experience Based Techniques (EBT) is correct?

EBT use tests derived from the test engineers’ previous experience with similar technologies.

EBT is based on the ability of the test engineer to implement various testing techniques.

EBT is done as a second stage of testing, after non-experienced-based testing took place.

EBT require broad and deep knowledge in testing but not necessarily in the application or technological domain.

NEW QUESTION 38
Which ONE of the following statements about acceptance testing is NOT correct?

Testing of disaster recovery and backup/restore is usually NOT part of acceptance testing.

The customers or system users are often responsible for the acceptance testing.

The main goal of acceptance testing is to build confidence in the system, not find defects.

Acceptance testing is the last level of testing performed prior to system release.

NEW QUESTION 39

NEW QUESTION 41
Given the following requirement:
Requirement ID: 2 8
Requirement Description Additional Entrance Fee
Detailed Description
An additional fee of S3 is charged during the weekend, but
1) Visitors aged under 7 are not charged.
2) Visitors aged 7 to 13 inclusive get a 20% discount off the additional fee.
3) Visitors aged greater than 65 get a 50% discount off the additional fee.
Age should be an integer of 0 or above.
Weekend means Friday to Sunday inclusive.
Which of the following statements is NOT correct?

Thursday is a valid input boundary value.

A minimum of 6 valid test cases are derived from boundary value analysis based on input age.

$3.01 is a valid output boundary value.

7 and 13 are boundary values for the equivalence partition including age 10.

Boundary value analysis is a technique that tests boundary values between partitions of equivalent data. Boundary values are values at the edge of an equivalence partition or at the smallest incremental distance on either side of an edge. Boundary value analysis can be applied to both input and output values. Based on the given requirement, we can identify two input values: age and weekend. Age should be an integer of 0 or above, and weekend means Friday to Sunday inclusive. The following statement is not correct:
A) Thursday is a valid input boundary value. This statement is not correct, as Thursday is not a boundary value for the input weekend. The boundary values for the input weekend are Friday and Sunday, as they are at the edge of the equivalence partition that represents weekend days. The following statements are correct:
B) A minimum of 6 valid test cases are derived from boundary value analysis based on input age. This statement is correct, as we can derive six valid test cases based on input age by using the minimum and maximum values for each equivalence partition defined by the requirement. The equivalence partitions for input age are: under 7 (0 to 6), 7 to 13 inclusive (7 to 13), and greater than 65 (66 and above). The minimum and maximum values for each partition are: 0 and 6, 7 and 13, and 66 and any value above it.
C) $3.01 is a valid output boundary value. This statement is correct, as $3.01 is a boundary value for the output additional fee. The additional fee can have four possible values depending on the input age: $0 (for visitors aged under 7), $2.40 (for visitors aged 7 to 13 inclusive with a 20% discount), $1.50 (for visitors aged greater than 65 with a 50% discount), and $3 (for visitors aged between 14 and 65). The boundary values for the output additional fee are $0 and $3, as they are at the edge of an equivalence partition or at the smallest incremental distance on either side of an edge. Therefore, $3.01 is a valid output boundary value, as it is at the smallest incremental distance above $3.
D) 7 and 13 are boundary values for the equivalence partition including age 10. This statement is correct, as 7 and 13 are boundary values for the equivalence partition that represents visitors aged 7 to 13 inclusive. This partition includes age 10, which is an internal value within the partition. Verified Reference: [A Study Guide to the ISTQB Foundation Level 2018 Syllabus – Springer], Chapter 4, page 37-38.

NEW QUESTION 42
A test engineer finds a defect while testing. After the developer has fixed the defect, the test engineer decides to re-run a complete section of the tests. Which of the following is correct?

The test engineer should re-run the tests, in order to ensure that new defects have not been introduced by the fix.

The lest engineer should not re-run the tests, as they have already been run, and results recorded.

The test engineer should not re-run the tests, they should be part of the developer tests.

The test engineer should re-run the tests, because the defect shows that the test cases need to be updated.
