Question#1

The following depicts a main path through the use case "Return Item":
USE CASE: Return Item
Use case ID: UC14
Purpose: Customer selects an item for return and prints return label
Actors: Customer, System
Pre-conditions: Customer has opened shopping site home page



Exceptions:
E1: Customer is already logged-in (Main Menu displayed) - Step M2
E2: Invalid log-in details entered (Prompt to retry) - Step M4
E3: Third invalid log-in attempt (Account frozen for 24 hours) - Step M4
E4: Go-Back requested - Steps M7 (to Main Menu) and M9 (to Order History)
You are to apply the Use Case test technique with the following rules:
One test case for the basic behavior
Multiple alternate behaviors may be combined if compatible
Nested alternate behaviors (like retry) should be amalgamated
How many test cases should be designed?

A. 3
B. 1
C. 5
D. 2

Explanation:
Basic Behavior (1 test case) - The standard process of item return without errors.
Alternate Behaviors (2 test cases):
Test Case 2: Incorporates E1 (Already logged in) and the normal flow.
Test Case 3: Includes E2 (Invalid login attempt), E3 (Third attempt - account frozen), and E4 (Go-Back option).
Combining compatible exceptions and following the amalgamation rule leads to3 test cases in total.
Therefore, the correct answer is A (3).

Question#2

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 new user interface allowing 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 a SCRUM methodology with 2-week sprints and well-specified user stories.
Which option below describes the BEST test techniques to apply for each project?

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

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 the combinations 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 is B (Pairwise and exploratory testing).

Question#3

Which of the following descriptions is an example of the use of defect taxonomies?

A. Grouping defects found during execution by functional area
B. Following a defect management process throughout testing
C. Running tests with the aim of finding as many defects as possible
D. Using a list of known defect types to penetrate the security of computer systems

Explanation:
The description that is an example of the use of defect taxonomies is using a list of known defect types to penetrate the security of computer systems. A defect taxonomy is a classification of defects based on their characteristics, causes, or effects. A defect taxonomy can be used to design test cases that target specific types of defects or vulnerabilities in a system or component.

Question#4

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

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. Verified References: [ISTQB® Certified Tester Advanced Level Test Analyst CTAL-TA], Section 3.6.1, page 43.

Question#5

Ticket machines are to be installed at the train station of a major European airport to enable newly arriving passengers to quickly purchase their tram tickets.
You are testing this new application and the following Use Case has been provided:
USE CASE: Credit Card Purchase
Use Case ID: UC-001401
Purpose: To purchase a single ticket to the city center
Actors: User
Preconditions: Ticket machine is at the "select language" screen, user has a valid credit card



You have been asked to review this Use Case.
Which ONE of the following checklist items are TRUE and will pass?

A. All alternate paths are identified
B. All error messages are defined
C. Each path is testable
D. The main path is clearly defined

Explanation:
A (All alternate paths are identified): Incorrect. The use case does not mention any alternate paths or exceptions.
B (All error messages are defined): Incorrect. There are no error message details provided.
C (Each path is testable): Incorrect. The absence of alternate paths makes this questionable.
D (The main path is clearly defined): Correct. The use case clearly outlines the main (happy) path from language selection to ticket purchase.
Therefore, the correct answer is D (The main path is clearly defined).
