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.

Agile Development and Automation:

Agile methodologies encourage frequent updates to the test automation suite to stay in sync with incremental development. This ensures that testing can validate new changes as soon as they are made.

Updating During Iteration:

Updating the test suite as code is developed allows for immediate feedback on changes, improving efficiency and reducing defect leakage.

Conclusion:

Option D is correct because it aligns with continuous integration and Agile principles.

Quantitative questionnaires are best suited for eliciting non-functional requirements from a large number of stakeholders. This is because they allow for the collection of measurable, statistical data that can be analyzed to understand the stakeholders' needs regarding system qualities like performance, usability, and reliability.These questionnaires can be designed to include specific questions about non-functional aspects, which can then be quantitatively assessed to inform the acceptance criteria1.

Story Mapping is a requirements engineering technique that provides a visual representation of the user journey within the system. It helps in identifying how different user groups interact with the system, thereby uncovering gaps and inconsistencies in user stories. This technique allows teams to prioritize and plan releases based on the user's experience and needs.

Reference= The ISTQB Advanced Level Agile Technical Tester syllabus and training materials discuss the use of various requirements engineering techniques, including Story Mapping, to better understand and define user interactions with the system12.

Exploratory testing is a type of testing that emphasizes the personal freedom and responsibility of the individual tester to continually optimize the quality of his/her work by treating test-related learning, test design, test execution, and test result interpretation as mutually supportive activities that run in parallel throughout the project. While exploratory testing can be highly effective in certain contexts, for safety-critical systems, it is generally not recommended. Safety-critical systems require a high degree of assurance and predictability that each component of the system behaves as expected under all circumstances. Manual black-box tests, which are more structured and can be thoroughly planned and documented, are preferred in these scenarios to ensure comprehensive coverage and traceability.

Reference= The ISTQB Advanced Level Agile Technical Tester syllabus and training materials provide guidance on the appropriate use of different testing techniques in various contexts, including the recommendation of structured manual black-box testing over exploratory testing for safety-critical systems1234.
