NEW QUESTION # 26
Consider the following decision table:

This decision table has been created to test the following specification: Persons that study at a university (C1) and have parents whose total annual income is less than € 30.000 (C2), receive a scholarship In in addition to these qualifications, if they also live away from home (C3), they receive an addition to their scholarship (A2) How many cases are left when this decision table is collapsed?

• A. 0
• B. 1
• C. 2
• D. 3

Answer: C

Explanation:
Two cases are left when this decision table is collapsed. A decision table is a technique that shows the combinations of conditions and actions for a given scenario. A decision table that is collapsed eliminates the combinations that are invalid or impossible, such as having a scholarship without meeting the qualifications.
The two valid cases for this scenario are:
* C1 = Y, C2 = Y, C3 = Y, A1 = Y, A2 = Y
* C1 = Y, C2 = Y, C3 = N, A1 = Y, A2 = N

NEW QUESTION # 27
Which of the following statements about defect-based techniques is TRUE?
SELECT ONE OPTION

• A. Defect-based testing is a technique that identifies defects in requirements early in the lifecycle
• B. In defect-based testing, the type of defect sought is used as the basis for test design
• C. Defect-based techniques are mainly used by developers at the component test level
• D. The coverage criteria for black-box test techniques tend to be less systematic than for defect-based test techniques

Answer: B

Explanation:
Comprehensive and Detailed in Depth Explanation:
* Defect-based techniquesuse the knowledge of defects that have occurred in the past to develop test cases that target similar types of issues.
* Option Ccorrectly states that defect-based testing focuses on using known defect types as the basis for designing tests.
* Option Ais incorrect because defect-based testing can be applied at various levels, not just the component level.
* Option Bis incorrect since defect-based techniques do not necessarily guarantee more systematic coverage than black-box techniques.
* Option Dis incorrect because defect-based testing focuses on detecting specific defect types rather than verifying requirements early.
Hence, the correct answer isC (In defect-based testing, the type of defect sought is used as the basis for test design).

NEW QUESTION # 30
You are testing the processing of a critical traffic control system to which various regulations apply The processing of the input variables is dependent on defined ranges within which the actual retrieved data values can lie.
Which of the following black-box test techniques should you use to test the processing functionality of this system?

• A. State transition testing
• B. Pairwise testing
• C. Use case testing
• D. Equivalence partitioning enhanced with boundary value analysis

Answer: D

Explanation:
The best black-box test technique to test the processing functionality of this system is equivalence partitioning enhanced with boundary value analysis. Equivalence partitioning is a technique that divides the input domain into subdomains that are expected to behave similarly. Boundary value analysis is a technique that tests the values at or near the boundaries of an input domain. These techniques are suitable for testing a system that depends on defined ranges of input variables, as they can ensure that all subdomains and boundary values are covered by test cases.

You work for a software testing consultancy firm,SOFTEST, that specializes in the travel industry. It has built up a portfolio of clients across two main travel sectors: thecruiseandrailsectors. SOFTEST has an established test process, an experienced team of testers, and maintains comprehensive organizational defect taxonomies for both sectors.
A project has started for a new cruise sector client. It will deliver a newuser interfaceallowing customers to search for cruises using several drop-down fields, each with many values, providing a much greater range of combinations than customers previously had. The project is using aSCRUM methodologywith 2-week sprints and well-specified user stories.
Which option below describes the BEST test techniques to apply for each project?
SELECT ONE OPTION:

• A. Classification Tree (class combination coverage) and exploratory testing
• B. Pairwise and use case testing
• C. Decision table testing and checklist-based testing
• D. Pairwise and exploratory testing

Answer: D

Explanation:
Comprehensive and Detailed In-Depth Explanation:
* A (Pairwise and use case testing):Not ideal since use case testing is not as relevant to UI combination testing.
* B (Pairwise and exploratory testing):Correct. Pairwise testing efficiently handles thecombinations from multiple drop-down fields, while exploratory testing complements agile development (SCRUM) for discovering unexpected issues.
* C (Decision table and checklist-based testing):Not the most suitable combination for this context.
* D (Classification Tree and exploratory testing):Classification trees are less effective compared to pairwise in handling multiple combinations.
Therefore, the correct answer isB (Pairwise and exploratory testing).

NEW QUESTION # 35
An airline provides self-service check-in kiosks for its passengers. The user is asked to present the passport for reading, enter the flight booking number, the seats requested, the number of bags to check-in, and acknowledge that security requirements have been met. The machine then prints the boarding passes.
The following use case has been created:
USE CASE: SELF-SERVICE CHECK-IN
* Use case ID:UC23
* Purpose:Passenger checks-in using the self-service kiosk application.
* Actors:Passenger, System
* Pre-conditions:User selects to start self-service check-in at the kiosk and the system asks the user to place the passport on the reader.

You are to apply the Use Case test technique, where the following coverage rules have been defined in the test plan:
* One test case should be designed for the basic behavior.
* One test case should be designed for each alternate and error-handling behavior.
Applying these rules to the Self-Service Check-In Use Case, how many test cases should be designed?
SELECT ONE OPTION:

• A. 0
• B. 1
• C. 2
• D. 3

Answer: B

Explanation:
Comprehensive and Detailed In-Depth Explanation:
The use case has onebasic behavior(happy path) where all steps are completed without any errors.
In addition, there are7 error-handling cases (E1 to E7)that each require a separate test case to verify that the system correctly handles each error condition.
Therefore, the total number of test cases required is:
* 1 basic behavior test case
* 7 error-handling test cases
1+7=8
Hence, the correct answer isB (8).

NEW QUESTION # 36
You are testing an ATM based on the following use
ATM start screen is showing
1. The user inserts card
2. The user types in PIN
3 The user selects cash with receipt'
4. The user selects €50
5. The user selects no further service' Expected results
- The ATM provides €50 to the user
- The ATM returns the card and balance slip
- The ATM clears the screen
- The ATM returns to start menu
You are asked to review this use case.
You are asked to review this use case.
What is the most important information that is missing from this use case?

• A. Expected results not clearly defined
• B. The use case should also include alternative behaviour.
• C. More test cases are needed to achieve the minimum acceptable level of coverage.
• D. Nothing has been defined for expected response times.

Answer: B

Explanation:
The most important information that is missing from this use case is the alternative behaviour, which describes the exceptional or error flows of events that may occur during the execution of the use case. For example, the use case should specify what happens if the user enters an invalid PIN, if the ATM runs out of cash, if the user cancels the transaction, etc. The alternative behaviour is essential to test the robustness and reliability of the system under test.

Which of the following is the earliest test level where this requirement should start to be tested?
SELECT ONE OPTION:

• A. During system testing
• B. During beta acceptance testing
• C. During component testing
• D. During user acceptance testing using a WAMMI survey

Answer: A

Explanation:
Comprehensive and Detailed In-Depth Explanation:
* Component Testing (C) focuses on individual components or units and does not address usability or role-based testing.
* System Testing (D) is the first level where the complete and integrated system is tested as a whole.
It includes testing non-functional requirements such as usability, accessibility, and suitability for different user roles.
* User Acceptance Testing (A) and Beta Acceptance Testing (B) are done later and focus on validating the product according to user needs and real-world scenarios.
Since testing for role appropriateness and usability should start as early as possible in the testing lifecycle, the correct answer is D (During system testing).

NEW QUESTION # 39
Which statement BEST describes the activities performed by the Test Analyst during the TEST ANALYSIS stage of the test process?
SELECT ONE OPTION

• A. Defining the start and completion dates for the test analysis stage
• B. Ensuring that multiple product risks are covered by one test condition to reduce maintenance overheads
• C. Producing high-level test cases and defining the supporting test data
• D. Applying test techniques to reduce the likelihood of omitting important test conditions

Answer: D

Explanation:
Comprehensive and Detailed in Depth Explanation:
According to the ISTQB CTAL-TTA syllabus, theTest Analysisstage involves identifying test conditions based on test basis documentation, requirements, and risk analysis. The primary focus is on analyzing the test basis to identify what needs to be tested. Applying test techniques during this stage helps reduce the risk of missing important test conditions. Therefore, Option A correctly states that test techniques are applied to minimize the risk of omitting important conditions.
Option B is incorrect because combining multiple product risks into one test condition can lead to overlooking specific risks, which contradicts the goal of thorough test analysis.
Option C is incorrect as defining dates is part of planning, not analysis.
Option D is incorrect because producing high-level test cases and defining data are tasks related to test design, which follows test analysis.
This detailed breakdown aligns with the ISTQB syllabus, emphasizing that test analysis primarily deals with identifying test conditions through the application of test techniques.
