NEW QUESTION # 42
REQ1 a sun cancer warning system shall produce a daily score sheet based on the number of hours expose to the sun and the intensity of sun radiation.
REQ2 The number of hours exposed to the sun shall be categorized in A (below 2), B (2 to 4 hours) or C (more than 4 hours) REQ3 The intensity of sun radiation shall be labelled as low, medium, high, or extreme.
Based on the requirements stated above a Test Analyst has defined the following three test cases:
How many test conditions to be identified from requirements REQ2 and REQ3, are NOT covered by the three test cases:
- A. 0
- B. 1
- C. 2
- D. 3
Answer: A
Explanation:
Explanation
Test conditions are the inputs and expected outputs of a test case, based on the requirements. To identify the test conditions from REQ2 and REQ3, we need to consider all the possible combinations of the categories of hours exposed to the sun (A, B, C) and the labels of sun intensity (low, medium, high, extreme). There are 12 such combinations in total. However, the three test cases given only cover 3 of them: A-low, C-medium, and A-low. Therefore, there are 9 test conditions that are not covered by the test cases. However, some of these test conditions are invalid or impossible, such as A-extreme or C-low, because the sun intensity is correlated with the hours exposed to the sun. Therefore, we need to exclude these invalid test conditions from the count.
According to the Skin Cancer Foundation, the sun intensity is usually low before 10 a.m. and after 4 p.m., medium between 10 a.m. and 1 p.m., high between 1 p.m. and 4 p.m., and extreme between 10 a.m. and 4 p.m.
in the summer or at high altitudes. Based on this information, we can assume that the valid test conditions are:
* A-low
* A-medium
* B-medium
* B-high
* C-high
* C-extreme
These six test conditions are not covered by the three test cases, so the answer is C. 6. References = ISTQB Certified Tester Advanced Level Syllabus Technical Test Analyst (Section 3.2.1), Be Safe in the Sun (Section

NEW QUESTION # 46
Consider the following user story: As a student, I want to be able to buy a parking pass (priority: high) Acceptance criteria
- The student will not receive the parking pass if the payment is insufficient.
- Only registered students can buy a parking pass.
- The student can only buy one parking pass each month.
Which of the following checklist items would result in finding a defect for the user story?
- A. Does the story follow the commonly used format "As a < >, I want < > so that < >"?
- B. Is the story written from the view of the person who requested it?
- C. Is the story prioritized?
- D. Are the acceptance criteria defined and testable?
Answer: D
Explanation:
Explanation
The acceptance criteria are the conditions that must be met for the user story to be considered done and acceptable by the user. They should be defined and testable, meaning that they are clear, measurable, and verifiable. The acceptance criteria for the user story are not well-defined and testable, because they do not specify how the payment is made, how the registration is verified, andhow the monthly limit is enforced.
These details are important for testing the functionality and quality of the user story, and should be included in the acceptance criteria. References = ISTQB Certified Tester Advanced Level Syllabus Test Analyst, Section
2.2.1, Use Case Testing1; How to Write a Good User Story, Section Acceptance Criteria2; Test User Stories with these 10 Tests, Section Testable3
NEW QUESTION # 47
You have been given a user story for an ATM application and have been reviewing it. The following are two of the acceptance criteria:
AC 1: The account balance must be displayed to the user as fast as possible to ensure they do not leave during the transaction.
AC 2: The user must log in easily before they can display their balance From the information provided here and by applying the review checklist in the syllabus, what is the major problem with the acceptance criteria?
- A. The acceptance criteria are not prioritized
- B. The story is not independent from other stories
- C. The feature is not clearly defined
- D. The acceptance criteria are not testable
Answer: D
Explanation:
Explanation
The correct answer isB.The acceptance criteria are not testable.
The acceptance criteria are not testable
The acceptance criteria are not testable because they are vague and subjective. They do not specify any measurable or observable outcomes or conditions that can be verified by the test analyst.For example, what does "as fast as possible" or "easily" mean in terms of performance and usability? How can the test analyst determine if the user does not leave during the transaction or if they log in easily? The acceptance criteria should be rewritten to include clear and quantifiable criteria, such as response time, error rate, user satisfaction, etc1.

NEW QUESTION # 48
To enhance both the effectiveness and efficiency of the test design phase, the purchase of a test design tool is being considered. Which one of these statements best characterizes a test design tool?
- A. A test design tool enables tests to be executed automatic ally.
- B. A test design tool enables individual tests to be traced to requirements
- C. A test design tool generates test inputs from requirements
- D. A test design tool validates models of the software.
Answer: C
Explanation:
Explanation
A test design tool is a tool that helps testers create test cases, or at least test inputs, based on the requirements and specifications of the software. It can use various techniques, such as equivalence partitioning, boundary value analysis, decision tables, state transition diagrams, etc., to generate test inputs that cover different aspects of the software functionality and quality. A test design tool does not validate models of the software, execute tests automatically, or trace tests to requirements, although these may be features of other types of testing tools.

NEW QUESTION # 49
As a Test Analyst on a project using the V-model lifecycle model, you have been working with expert business users for a program designed to assist car buyers in selecting options for new car models. The program has been in use for some time, and now your company has decided to implement some significant improvements, based on customer and sales representative's feedback.
You visit specific locations and gather information on how the product is currently being used, spend time with expert users, and walk through their envisioned scenarios.
Based on this information, what are you using for your test basis and what information is still missing?
- A. State transitions; the events that cause the transitions between states
- B. Use cases; the validation that the transactions are realistic
- C. State transitions; the starting and ending states
- D. Use cases; the exception and error handling behaviors
Answer: B
Explanation:
Explanation
Use cases are a test basis that describe the interactions between the users and the system in terms of scenarios.
Use cases capture the functional requirements and the expected outcomes of the system. By visiting locations, spending time with expertusers, and walking through their scenarios, the test analyst is using use cases as the test basis. However, use cases do not provide enough information to validate that the transactions are realistic, such as the prices, discounts, taxes, and fees involved in the car buying process. This information is still missing and needs to be obtained from other sources, such as the business rules or the data model. References
