Q26. You are a tester in an agile team. The user story you are due to test is still under development so your tests are blocked. The main issue holding progress on this user story is that the developer’s unit tests are constantly failing.
As an agile tester, which of the following actions should you take?

Review the design of the problematic user story and improve it where possible.

Create a bug report for each of your blocked tests.

Work together with the developer, suggesting reasons why the tests are failing.

Use the time to improve and automate existing test cases of other user stories.

Q27. You have been asked to execute an exploratory testing session on Park & Ride system. The test charter has been titled as “Buy a bus ticket”. As a result, a number of defects were reported, the titles of which are listed below.
Which defect is out of scope for the given test charter?

Price for a bus ticket was calculated incorrectly.

Failed to buy a bus ticket after 18:00.

Failed to buy a bus ticket when the network connection to the Central System is down.

Payment for parking ticket is restricted to cash only (no credit card supported).

Q28. You are a tester in an agile team. The user story you are due to test is still under development so your tests are blocked. The main issue holding progress on this user story is that the developer’s unit tests are constantly failing.
As an agile tester, which of the following actions should you take?

Review the design of the problematic user story and improve it where possible.

Create a bug report for each of your blocked tests.

Work together with the developer, suggesting reasons why the tests are failing.

Use the time to improve and automate existing test cases of other user stories.

Q29. Which of the following describes the main purpose of a task management tool in agile projects?

A task management tool is used by team members to share ideas and collaborate on assigned tasks.

A task management tool is used to manage and track user stories, tests and other tasks.

A task management tool is used to store source code and automated tests.

A task management tool allows developers to continuously integrate their code.

Q30. Which of the following statements about the benefits of the Agile processes promoting early and frequent feedback is NOT true?

In Agile projects where feedback is provided early and frequently, defects and incorrect requirements are caught earlier and those problems can be fixed faster.

Feedback from well-conducted Agile retrospectives can be used to positively affect the development process over the course of the next iteration.

Early and frequent feedback enables the team to deliver the features that represent the highest business value to the customer first.

Increasing the frequency of feedback and communication between all the stakeholders involved in Agile projects eliminates all communication problems.

Q31. Which of the following is a benefit of a whole-team approach?

Enables reduction in test duplication as the testers and test engineers function as a single team.

Enables testers to execute their responsibility for quality for the combined team.

Enables the team to focus on solely their separate areas of expertise and responsibility.

Enables the various skill sets within the team to be leveraged to the benefit of the project.

Q32. Your agile team is using the Testing Quadrants to ensure that all important test levels and test types are covered in the test plan.
In relation to Quadrant 3 – business facing and product critique, what should be considered for the plan?

Exploratory Testing

Prototype Testing

Performance Testing

Functional Testing

Q33. Which of the following sentences related to Risk-based testing is CORRECT?

Risk-based testing fits well in Agile development processes, as risks are analyzed twice – during release and iteration planning.

Risk-based testing does not fit well in Agile development processes, as short iterations mandate short test times.

Risk-based testing does not fit in Agile development processes, as each iteration focuses on limited parts of the product.

Risk-based testing fits well in Agile development processes, as risks are easy to identify when the work is divided into user stories.

Q34. You are working on an Agile project and have been asked to implement exploratory testing for the current sprint. Which one of the following is a correct approach to adopt?

Allocate independent testers to design exploratory tests using test charters in time boxed sessions. Plan to run all sessions in parallel with each session lasting more than 5hours.

Ask experienced testers to try and find new defects by using the system without the constraint of documentation and tools.

Use testers who have not been involved in the sprint to write new test cases from the user stories. These test cases are then executed in a time boxed session for the sprint.

Ask experienced testers to prepare test charters for time boxed sessions lasting no more than 2hours.
Tests should be designed and executed within each session using heuristics, creativity and intuition.

Q35. Which of the following sentences related to Risk-based testing is CORRECT?

Risk-based testing fits well in Agile development processes, as risks are analyzed twice – during release and iteration planning.

Risk-based testing does not fit well in Agile development processes, as short iterations mandate short test times.

Risk-based testing does not fit in Agile development processes, as each iteration focuses on limited parts of the product.

Risk-based testing fits well in Agile development processes, as risks are easy to identify when the work is divided into user stories.

Q36. In a sprint planning, the product owner presents a user story written on a card. The team starts having a discussion with the product owner to get an understanding on how the software should work.
The user story written on the card is:
“As a customer, I want to subscribe to the mailing list so that I can receive the latest deal in an email.” By applying the 3C concept, which ONE of the following statements is CORRECT?

Conversation should include the acceptance criteria discussion.

The card should contain requirements not the user story.

Product owner has written a user story and confirmation is not needed.

The conversation is not required and the team should start developing.

Explanation
The 3C concept of user stories consists of three elements: card, conversation, and confirmation12. The card is a written description of the user story that captures the essence of the feature or functionality from the user’s perspective. The conversation is a dialogue between the product owner and the development team to clarify the details, assumptions, and expectations of the user story. The confirmation is a set of criteria or tests that verify that the user story is implemented correctly and meets the user’s needs12. Therefore, by applying the 3C concept, the correct statement is A, as the conversation should include the acceptance criteria discussion. This will help the team to understand the scope, priority, and value of the user story, as well as the conditions of satisfaction that the product owner expects12. The other statements are incorrect, as they violate the 3C concept. Statement B is wrong, as the card should contain the user story, not the requirements. The user story is a brief and informal way of expressing the user’s goal and benefit, while the requirements are more detailed and specific descriptions of how the software should work. The requirements can be added later as part of the conversation or confirmation12. Statement C is wrong, as the product owner has written a user story, but confirmation is still needed. The confirmation is a vital part of the 3C concept, as it ensures that the user story is testable, measurable, and verifiable. The confirmation also helps to avoid ambiguity, misunderstanding, or disagreement between the product owner and the development team12. Statement D is wrong, as the conversation is required and the team should not start developing without it. The conversation is an essential part of the 3C concept, as it allows the team to ask questions, share ideas, and collaborate with the product owner to refine the user story and reach a shared understanding. The conversation also helps to identify the dependencies, risks, and assumptions that may affect the implementation of the user story12.

Q37. User Story: As a user I want to be able to calculate tax percentage based on amount of income.
What is the best black box test design technique for verifying the accuracy of this user story?

Statement testing – test all statements in income calculation.

User story testing – test that the user can enter an income amount and get a result.

State transition testing – test all states of income entry.

Equivalence partitioning – test with low, medium and high income.
