ISTQB - Agile Public

Review 40 ISTQB-AGILE-PUBLIC practice questions with answer explanations and community insights.

Question 1

Which of the following statements about the Planning poker test estimate technique are CORRECT? i) Planning poker is a consensus based technique using a deck of cards. ii) A low test estimate usually means the story should be broken down into multiple smaller stories. iii) A high test estimate usually means the story should be broken down into multiple smaller stories. iv) One poker round is played and then consensus has to be reached. v) The risk level of each backlog item should be decided before the poker session.

  1. i, iii, v
  2. i, ii, iv
  3. i, ii, iii
  4. i, iii, iv

Question 2

What is the main benefit of the Test Pyramid?

  1. It helps in evaluating the amount of test cases needed.
  2. It means testing is involved early in the development cycle.
  3. It acts as a metric for testing progress.
  4. It shows complexity of testing activities.

Question 3

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?

  1. User story testing - test that the user can enter an income amount and get a result.
  2. Equivalence partitioning - test with low, medium and high income.
  3. Statement testing - test all statements in income calculation.
  4. State transition testing - test all states of income entry.

Question 4

You are developing the code that controls an industrial Espresso machine which will be operated by waiting staff in restaurants. The machine is rather complicated and has lots of switches and buttons, so in the next iteration instructions will be provided to the operator on a small LCD screen. A User Story for the Operator-instructions module is as follows: "As an operator of the Espresso machine, I would like to know how to steam milk, so I can add steamed milk to the coffee." The following is a list of risks identified for this story, with assigned probability and impact. Which of these is most correct in the context of the given User Story?

  1. An untrained customer will attempt to use the coffee machine. Probability: High. Impact: High
  2. The instructions may be incorrect or appear in the wrong order. Probability: Low. Impact: High
  3. Operators will not read the instructions and will try various switches and buttons until something works. Probability: Low. Impact: Low
  4. A small child may try to steam milk. Probability: High. Impact: Low

Question 5

During a retrospective, which of the following items would be the LEAST effective to generate discussions on process improvement?

  1. The automation tests failed frequently without any logs to help in debugging the failure reason.
  2. For the last sprint the estimated and actual effort were much higher than the team capacity.
  3. One of the testers was regarded as being both disruptive and lazy and did not contribute to team success.
  4. The build process was slow and this often caused delays waiting for the build to complete.
