Service virtualization is a technique that allows teams to simulate the behavior of dependent systems or components that are not readily accessible during the testing phase. In the context of developing an e-shop application with a payment gateway still under development, service virtualization offers the following benefits:

Realistic Testing: It enables the testing of the e-shop application (SUT) in a manner that closely resembles the final production environment by simulating the payment gateway's behavior.This allows for the identification of defects and issues early in the development process12.

Simplification of the Test Environment: By using virtual services, the complexity of the test environment is reduced.There's no need to set up and maintain actual integrations with the third-party payment gateway until it is fully developed, which simplifies the testing process and infrastructure requirements12.

Reference= The benefits of service virtualization are well-documented in the ISTQB Advanced Level Agile Technical Tester syllabus and other software testing resources, which highlight its role in enabling early and realistic testing, as well as simplifying the test environment3412.

The mnemonic FIRST is used to describe good unit tests in Agile software development. Each letter stands for a quality that the tests should possess:

F- Fast: Tests should run quickly.

I- Isolated: Tests should not depend on each other.

R- Repeatable: Tests should yield the same results every time.

S- Self-Validating: Tests should have a boolean output (pass or fail).

T- Thorough: Tests should cover every part of the code.

Option D correctly states the meanings of the letters IRST in the context of the FIRST mnemonic.

The epic described is broad and encompasses a system that involves multiple stakeholders and vehicle types, indicating that it is not a small piece of work that can be completed in a short iteration.This violates the 'Small' criterion of INVEST, which states that stories should be the smallest piece of work that delivers useful functionality to fit within an iteration12. Additionally, the epic's acceptance criteria apply to all user stories derived from it, suggesting that the stories are not independent of each other, as changes to one could affect the others.This goes against the 'Independent' criterion, which emphasizes that stories should be self-contained to avoid delays caused by dependencies12.

Given the high risk level and the need for a regression-averse strategy due to potential changes in screen design and functionality, the best test approach would involve a strong emphasis on test automation to ensure that new changes do not break existing functionality. Exploratory testing is neutral as it can be useful but is not the primary focus. Manual black-box testing is recommended to verify that the system meets the requirements from an end-user perspective.

Therefore, the option that aligns with these needs is:

Test Automation: + (highly recommended)

Exploratory Testing: o (neutral/optional)

(manual) Black-box testing: (recommended)

This corresponds toOption 1, which suggests a heavy reliance on automated testing to manage regression risks efficiently, while still incorporating manual black-box testing to cover user experience aspects.

Reference= The ISTQB Advanced Level Agile Technical Tester documents and training resources emphasize the importance of test automation in Agile projects, especially when dealing with high-risk levels and the need for regression testing1.Additionally, the resources available at Software Testing Help provide insights into Agile testing strategies and best practices that support such an approach2.

Acceptance Test-Driven Development (ATDD) is a collaborative practice that involves the team members with different perspectives, such as customer, development, and testing, to define acceptance tests that serve as requirements1.ATDD can be applied to all types of requirements, including functional, non-functional, and technical stories, to ensure a shared understanding and agreement on the expected behavior of the software12.It is a valuable approach in Agile environments where continuous collaboration is essential, and it complements TDD by focusing on the behavior and requirements from the user's perspective3.While ATDD does not require automated acceptance tests, automating them can enhance the process by allowing for more frequent and consistent execution1.

Test automation is not limited to the automation of test execution. It also includes the configuration of test environments, which is essential for ensuring that tests run in a stable and controlled setting.This broader view of test automation supports continuous integration and delivery practices, which are fundamental in Agile projects.Reference= The ISTQB Advanced Level Agile Technical Tester syllabus outlines the importance of test automation within Agile projects, including the creation and implementation of various Agile test approaches and supporting continuous integration and delivery123.

Acceptance Test-Driven Development (ATDD) is a collaborative approach that involves customers, developers, and testers to define acceptance criteria before development begins. This practice helps ensure that all stakeholders have a shared understanding of the requirements and can prevent misunderstandings like those experienced in the first release.By using examples in ATDD, the team can clarify what the software should do, which aligns with the user stories and supports the Test-Driven Development (TDD) process12.

Reference= The ISTQB Advanced Level Agile Technical Tester documents and resources from Software Testing Help discuss the benefits of ATDD in aligning team members and stakeholders on the expected outcomes of user stories, which is particularly useful when there have been previous misunderstandings34.

The TDD process, as described, seems to lack comprehensive testing that covers all the acceptance criteria. Specifically, the tests provided by the developers do not address the full range of input validation, such as ensuring that names with up to 30 characters are accepted and that standard error processing is in place to limit user errors. This indicates that the tests are insufficient and need to include more options to fully validate the feature against its acceptance criteria.The ISTQB Advanced Level Agile Technical Tester syllabus emphasizes the importance of creating testable acceptance criteria within an Agile team and implementing various Agile test approaches using appropriate techniques12.It also highlights the need for supporting and contributing to test automation activities in an Agile project12, which includes ensuring that all acceptance criteria are met and that tests are sufficiently robust to catch potential errors.

The correct use of Behavior-Driven Development (BDD) to design test scenarios involves specifying the behavior in a given-when-then format. This format helps to clarify the conditions under which a particular outcome should occur. Option A follows this structure correctly:

Giventhat the shopper scans their card (the precondition),

Whenthey checkout (the action),

Thenthey should receive all the quantity discounts for everything they have purchased (the expected outcome).

This scenario clearly outlines the behavior of the system in response to the user's actions, which is central to BDD.

Reference= The ISTQB Advanced Level Agile Technical Tester syllabus emphasizes the importance of creating testable acceptance criteria for a given user story using requirements engineering and test techniques, which include the application of BDD in the context of a given user story12.
