Question No. 1

Which of the following tools can be used by developers, testers and quality assurance personnel in looking for defects prior to dynamic testing?

Show Answer Hide Answer
Correct Answer: A

A static analysis tool can be used by developers, testers and quality assurance personnel in looking for defects prior to dynamic testing, because it can analyse the code or design of the software under test without executing it and identify errors such as syntax errors, missing declarations, undefined variables, unused variables, or unreachable code . The other options are not tools that can be used by developers, testers and quality assurance personnel in looking for defects prior to dynamic testing. Option B is not a tool that can be used for this purpose, because a modeling tool is used to create graphical or textual representations of the software under test, such as state diagrams, data flow diagrams, or use cases . Option C is not a tool that can be used for this purpose, because a test data preparation tool is used to generate or manipulate data that are needed for executing the test cases or procedures . Option D is not a tool that can be used for this purpose, because a configuration management tool is used to manage and control the versions and changes of the software under test and the testware .

Question No. 3

Given the following requirement:

Which of the following statements is NOT correct?

Show Answer Hide Answer
Correct Answer: D

The requirement given in the image specifies an additional fee of $3 that is charged during the weekend, with some exceptions and discounts based on the age of the visitors. To test this requirement, we can use boundary value analysis, which is a specification-based test technique that involves testing the values at or near the boundaries of an equivalence partition. An equivalence partition is a set of values that are expected to be treated in the same way by the system under test. For example, based on the requirement, we can identify the following equivalence partitions for the input age:

EP1: Age < 0 (invalid)

EP2: Age = 0 (valid, no charge)

EP3: 0 < Age < 7 (valid, no charge)

EP4: Age = 7 (valid, 20% discount)

EP5: 7 < Age < 13 (valid, 20% discount)

EP6: Age = 13 (valid, 20% discount)

EP7: 13 < Age < 65 (valid, full charge)

EP8: Age = 65 (valid, 50% discount)

EP9: Age > 65 (valid, 50% discount)

The boundary values for each equivalence partition are the values at or near the edges of the partition. For example, the boundary values for EP3 are 1 and 6. The boundary values for EP4 are 6 and 7. The boundary values for EP5 are 7 and 12. And so on.

To test this requirement using boundary value analysis, we need to select one value from each boundary and test it with different combinations of weekend and weekday. For example, we can select the following values:

BV1: Age = -1 (from EP1)

BV2: Age = 0 (from EP2 and EP3)

BV3: Age = 6 (from EP3 and EP4)

BV4: Age = 7 (from EP4 and EP5)

BV5: Age = 12 (from EP5 and EP6)

BV6: Age = 13 (from EP6 and EP7)

BV7: Age = 64 (from EP7 and EP8)

BV8: Age = 65 (from EP8 and EP9)

BV9: Age = 66 (from EP9)

We can then create test cases using these values and different combinations of weekend and weekday. For example:

TC1: Age = -1, Weekend = Yes -> Invalid input

TC2: Age = -1, Weekend = No -> Invalid input

TC3: Age = 0, Weekend = Yes -> No charge

TC4: Age = 0, Weekend = No -> No charge

TC5: Age = 6, Weekend = Yes -> No charge

TC6: Age = 6, Weekend = No -> No charge

TC7: Age = 7, Weekend = Yes -> $2.40 ($3 - 20% discount)

TC8: Age = 7, Weekend = No -> No charge

TC9: Age = 12, Weekend = Yes -> $2.40 ($3 - 20% discount)

TC10: Age = 12, Weekend = No -> No charge

TC11: Age = 13, Weekend = Yes -> $2.40 ($3 - 20% discount)

TC12: Age = 13, Weekend = No -> No charge

TC13: Age = 64, Weekend = Yes -> $3

TC14: Age = 64, Weekend = No -> No charge

TC15: Age = 65, Weekend = Yes -> $1.50 ($3 - 50% discount)

TC16: Age = 65, Weekend = No -> No charge

TC17: Age = 66, Weekend = Yes -> $1.50 ($3 - 50% discount)

TC18: Age =

66, Weekend = No -> No charge

Therefore, we need a minimum of18valid test cases to achieve100%boundary value coverage based on input age.

$3.01 is not a valid output boundary value because it is not a possible output value based on the requirement. The output values can only be $0, $1.50, $2.40, or $3 depending on the input age and weekend status.

You can find more information about boundary value analysis in [A Study Guide to the ISTQB Foundation Level 2018 Syllabus], Chapter 4, Section 4.2.


Question No. 4

You are responsible for applying the correct technique (or a review of the requirements document for a project to develop a new software application. You identify the reviewers and the required roles, including the meeting leader, who is the requirements document author, and a separate role for a scribe. Additionally, you decide to take a relatively informal approach to the requirements review. The goal of the review is to find defects in the requirements document, such as omissions, inconsistencies, and duplications. Another goal of the review is to improve the software application's usability and accessibility by considering the various stakeholders' viewpoints.

Which of the following statements BEST describes this scenario?

Show Answer Hide Answer
Correct Answer: B

This scenario is using a walkthrough review type and a perspective-based review technique. A walkthrough is a type of review that is relatively informal and led by the author of the work product. A perspective-based review technique is a technique that involves reviewing the work product from different viewpoints or perspectives of various stakeholders. The scenario matches these descriptions, as it involves an informal approach, a meeting leader who is the author of the requirements document, and a goal of improving the software application's usability and accessibility by considering the various stakeholders' viewpoints. Option A is incorrect, as a pair review is a type of review that involves only two people, usually the author and another team member. Option C is incorrect, as a checklist-based review technique is a technique that involves reviewing the work product against a predefined list of items or criteria. Option D is incorrect, as it combines the incorrect descriptions of options A and C.
