During a walkthrough of a new feature's requirements, the tester notices that the requirements document does not specify what happens when a user cancels an order after it has been shipped. What is the most appropriate action for the tester?

Note the missing scenario as a defect in the requirements and discuss it with the product owner to clarify the expected behavior.

Wait until the feature is developed and then test the cancellation behavior to see what the system does.

Assume the order cannot be cancelled after shipping and write a test case to verify this assumption.

Ask the developer to make a decision on the behavior during the walkthrough.

What is the 'three amigos' collaborative practice in agile?

A testing technique that uses three different test environments

A meeting involving a business representative, a developer, and a tester to discuss and clarify a user story

A method for prioritizing the product backlog using three criteria

A technique for estimating the size of user stories using three different scales

Which of the following is a typical criterion in the Definition of Ready for a user story?

The story has been fully coded and unit tested

The story has been deployed to production

The story has clear, testable acceptance criteria

The story has passed all regression tests

During backlog refinement, the product owner reads a user story: 'As a customer, I want to see my order status so I can track delivery.' The team is about to estimate it. As the agile tester, what is the most effective action to improve the test basis quality before estimation?

Mark the story as 'ready' because it follows the standard user story template and move on to estimation.

Volunteer to write the automated tests for the story during the current sprint to save time later.

Ask the product owner to define concrete acceptance criteria, such as which statuses are shown and how current the information must be.

Suggest the team use a three amigos session to discuss the story's business value and technical feasibility.

A team has a very tight deadline. The product owner has written user stories, but they are of poor quality (vague, missing edge cases). The team is under pressure to start development immediately. The tester believes that a full inspection of all stories would take too long. What is the most effective way to balance the need for speed with the need for test basis quality?

Skip the review and start development, relying on exploratory testing later to find any issues.

Have the developers start coding and the testers write test cases in parallel, hoping to catch issues during development.

Conduct a time-boxed, checklist-based review of the stories, focusing on the highest-risk areas and critical acceptance criteria.

Ask the product owner to rewrite all the stories to a higher standard before any development begins.
