A Scrum team is performing quality risk analysis during planning for the first iteration. User stories have associated risk items with levels determined by impact and likelihood. For multiple risk items, the user story's risk is the average of individual risk levels.
Which of the following statements would you expect most likely to be true?

• A.An estimation session after the risk analysis should consider only the risk level for effort estimation
• B.Potential issues with poorly written user stories should not be raised during risk analysis because they could influence how the risk level is determined
• C.While the identification of the risk items should be performed by the Product Owner, the assessment of the risk levels should be performed by the whole team
• D.Regardless of the risk level, more thorough test techniques should be selected for US-004 since it isthe user story with most associated risk items

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?

• A.Product owner has written a user story and confirmation is not needed.
• B.The conversation is not required and the team should start developing.
• C.The card should contain requirements not the user story.
• D.Conversation should include the acceptance criteria discussion.

4) Coaching development team in relevant aspects of testing.
5) Executing test-driven development tests.

• A.2, 5
• B.1, 3
• C.1, 3, 4
• D.2, 4, 5

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.

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

Consider an online application that allows registered users to pay the annual car tax based on the vehicle's engine power in kW. Given the following user story:
"As a customer I need the online application to calculate the annual car tax amount that I need to pay for my car:
* If the power of the vehicle is less than 20 kW, then the annual car tax is free
* If the power of the vehicle is more or equal than 20 kW but less or equal than 150 kW, then the annual car tax is 250 Euros
* If the power of the vehicle is more than 150 kW, then the annual car tax is 750 Euros" What is the MOST suitable use of a black-box test design technique for this user story?

• A.Use case testing Test the following use case (Actor=registered user):
  Pre-condition=registered user logged in Scenario=registered user inserts the power of the vehicle, making payment and logs out Post-condition=car tax paid and registered user logged out
• B.State transition testing. Test the transitions between the following states:
  logging in, inserting the power of the vehicle, making payment, logging out.
• C.Decision table testing. Test the following conditions:
  Conditions=registered user logged in; inserted power of the vehicle=20kW; Action=Car tax paid
• D.Equivalence partitioning. Test the annual car tax value for the following partitions:
  [power of the vehicle<20 kW ; 20 kW #power of the vehicles#150 kW; power of the vehicle>150 kW]
