Question 1

You are testing a large e-commerce system for household goods that is being implemented using Agile methodologies You are currently working on deriving tests for stories that are implementing the following epic.

As a customer I want to use the e-commerce system, so that I can have my purchased goods delivered to my house.

The story you are currently working on is:

As a customer I want to be told when my items will be delivered, so I can plan to be home.

You have been given the following charter that was proposed by another tester for testing this story

Login as a customer, buy enough of each item to qualify for free shipping for each item checkout and verify that no shipping fee has been added.

What is the main flaw in this charter?

Answer Options
Correct Answer: B
Explanation

The main flaw in the proposed test charter is that it does not cover the main functionality of the user story. The user story focuses on the customer wanting to be informed about the delivery time of their items so they can plan to be home. The proposed charter only tests for the absence of a shipping fee and does not address whether the system provides the customer with the delivery time information.

Reference= The ISTQB Advanced Level Agile Technical Tester syllabus emphasizes the importance of aligning test charters with the user story's main functionality to ensure that tests provide adequate coverage12.It is crucial in Agile methodologies to create and evaluate testable acceptance criteria that reflect the user story's objectives12.

Question 2

You are testing a large e-commerce system for household goods that is being implemented using Agile methodologies. You are currently working on deriving tests for stories that are implementing the following epic:

As a customer, I want to use the e-commerce system, so that I can have my purchased goods delivered to my house.

The story you are currently working on is: As a customer, I want to be told how many items I need to purchase, so I can receive free shipping.

Which of the following is an appropriate test charter for this story?

Answer Options
Correct Answer: C
Explanation

Step by Step Comprehensive Detailed Explanation with all Reference of Advanced Agile Technical Tester Objectives and Study Guides documents

Agile Methodology Alignment: Test charters in Agile emphasize the end-user perspective and should align with the story's goal. The focus should be on testing the user's experience with the free shipping threshold.

Test Scenario Completeness: Option C captures all critical elements:

Logging in as a customer (essential for user-specific functionality).

Testing the threshold message (key to the story's functionality).

Incrementally adding items until the threshold is met (realistic usage flow).

Completing the checkout process and verifying free delivery.

Other Options:

A is too broad and doesn't focus on the story's goal.

B is too narrow, failing to test dynamic thresholds and realistic flows.

D shifts the perspective to a supplier, which is irrelevant to the customer's story.

Conclusion: Option C best reflects the Agile principles of customer focus and iterative testing while fully covering the story's requirements.

Question 3

In a regression-averse test approach, what should be the focus of test automation?

Answer Options
Correct Answer: D
Explanation

Regression-Averse Test Approach:

This approach minimizes risks by ensuring tests remain relevant and effective over time. The key focus is maintaining and enhancing the regression suite to reflect changes in the software.

Continuous Improvement of Tests:

Keeping tests updated ensures the test suite is reliable and maintains high coverage. This involves adding tests for new features, removing obsolete tests, and refining existing ones.

Conclusion:

Option D is correct because it aligns with the goals of regression-averse approaches.

Question 4

Which statement correctly describes service virtualization''

SELECT ONE OPTION

Answer Options
Correct Answer: A
Explanation

Service virtualization is a technique used in software testing where a virtualized service simulates the behavior of dependent components that are not available for testing. This allows testing to proceed without waiting for the actual components to be available or operational. It is particularly useful in Agile and continuous testing environments where components may be developed in parallel or where integration points may not yet be stable. Service virtualization helps to create a more controlled and deterministic testing environment, enabling more thorough testing of the product under development.

Reference= The ISTQB Advanced Level Agile Technical Tester syllabus includes service virtualization as one of the key concepts to understand in the context of Agile testing123.
