ISTQB Agile Tester Extension Exam Crash Course Part 13


The following user-friendly questions prepared according to different K-Levels are of great help in reviewing your skills before appearing in ISTQB Agile Tester Extension Certification exam as per the latest syllabus.

Set of 10 Questions (Q. 121 to 130) with Explanation in Favour of the Correct Answer

The Correct Answer option has been Hi-lighted in Yellow.

Q. 121: (Level K3) In the poker planning session, the following stow points were given to a particular user story

Product owner: 3
Developers: 5
Testers: 8

Which action should the team agree on?


A. As the developers are developing the system, the developer estimates should be taken as correct when there is a conflict.

B. The team should hold a conversation to understand why the testers and product owner gave different story points for the work required for the story. Another round of the planning poker session should occur

following that discussion.

C. As the product owner owns the system, the customers' estimates should be taken as correct when there is a conflict.

D. The poker planning sessions should continue until all estimated story points are an exact match between product owner, developers, and testers.

Explanation in favor of the correct answer:

Option (A) False - as the entire team must agree on the estimate for the user story. The developer alone does not understand the complexity of developing or testing the functionality.

Option (B) True - as planning poker sessions should continue for the user story until the entire team is satisfied with the estimated effort.

Option (C) False - as the entire team must agree on the estimate for the user story. The customer alone does not understand the complexity of developing or testing the functionality.

Option (D) False - as it is not necessary that they match, a rule could be made that the highest estimate is taken, or an average taken of all three estimates. This is up to the team to decide before the planning poker session

<<<<<< =================== >>>>>>

Q. 122: (Level K3) In a Planning Poker session the team is estimating the effort for User story 1 and User story 2 which are related to the same feature.

The team has agreed on the story points for user story 1 but In the discussion of user story 2, the tester realized that he is not aware of the additional information about the business rules and external interfaces which may increase the testing effort for user story 1.

What should the tester do in this situation?


A. As the estimation is already done for user story 1, its better to raise the estimate for user story 2 this will compensate for the additional effect for the User story 1.

B. The tester should ask the team for a re-estimation of user story 1 based on the additional information.

C. The tester should raise his concern with the scrum master after the planning session and ask for an increase in the estimation.

D. The tester should not worry about the additional information as this was only an estimate anyway.


Explanation in favor of the correct answer:

Option (A) False - as the estimate is given for each story and should be agreed upon by the entire team.

Option (B) True - as the tester should ask the team to re-estimate. Additional information about business rules may affect the development and testing effort.

Option (C) False - as the entire team must agree on the estimate for the user story. The scrum master and the tester can't decide on their own.

Option (D) False – reason being if there is additional information, then the whole team should be aware of it and it should be used to re-estimate the story.

<<<<<< =================== >>>>>>

Q. 123: (Level K3) One of the Agile Teams are doing the estimation for the following user story:

"As an online Shopper, I want to delete items from my shopping cart so that I don't purchase items that I decide I don't want"

The tester has asked the following questions to the product owner to get a better understanding of the functionality for estimation purposes.

Which of the tester's question is not relevant for the estimation process?


A. Tester: "What business benefit does this story deliver?"
B. Tester: "What is the worst thing that could happen with this feature?"
C. Tester: "How will the end user actually use this feature?"
D. Tester: "What is the business priority for this user story?"


Explanation in favor of the correct answer:

Option (A) is incorrect – as this is relevant and will help in deciding the business problem this story is solving which will result in a better testing effort estimation.

Option (B) is incorrect – as this is relevant and will help in deciding the risk and the effort of testing required to cover the risk.

Option (C) is incorrect – as this is relevant and will help in deciding the testing effort and can be useful for the estimation.

Option (D) is correct – as this is not relevant and business priority of the user story will not help in estimating the user story.

<<<<<< =================== >>>>>>

Q. 124: (Level K3) In agile projects there is more need for testers to understand and develop test automation scripts than in traditional projects.

Of the following, which are the TWO reasons why this is a necessary skill on agile projects?

i. Requirements change daily and have to be regression tested. This rapid change requires automated tests because manual testing is too slow.

ii. The tests should generate feedback on product quality as early as possible. So all acceptance tests should be executed during each iteration, ideally as modifications are made. In practice that can only be realized by automated tests.

iii. Test-First and Continuous Integration practice require that the regression test suite is executed whenever changed code is checked-in. In practice that can only be realized by automated tests.

iv. Iterations or sprints are of fixed length. The team has to guarantee that all tests can be completely executed at the last day of each iteration/sprint. In practice, that can only be realized by automated tests.

v. Agile projects rely on unit testing rather than on systems testing. Since unit tests cannot be executed manually, all tests have to be automated tests.


A. i & iii
B. ii & v
C. v & v
D. ii & iii


Explanation in favor of the correct answer:

Statement (ii) & (iii) best describe the conditions for agile projects.

<<<<<< =================== >>>>>>

Q. 125: (Level K3) Agile team is assigned to a project to create a mobile interface for an existing web-based application.
