 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.

References = 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.

In Agile development, requirements engineering techniques are crucial for understanding and defining user needs and system requirements. The issues identified in the user story suggest the use of Personas and Storyboards. Personas are fictional characters created based on user research to represent different user types within a targeted demographic, attitude, and behavior set. They help in understanding various user needs and experiences, which is reflected in issue 1 and 2. Storyboards, on the other hand, are visual representations of a user’s interaction with the product, providing a narrative of how the product is used. They help in visualizing the process and identifying any missing elements, such as the lack of specified acceptance criteria for the booking process speed (issue 3) and the details on how confirmation is sent (issue 4). The need for a stub to test the payment method (issue 5) also aligns with the storyboard technique, which can help visualize the integration points and dependencies.

References = The ISTQB Advanced Level Agile Technical Tester syllabus and study resources provide insights into various requirements engineering techniques and their application in Agile environments12. These resources emphasize the importance of understanding user stories and acceptance criteria, which are key to uncovering the issues mentioned34567.

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.

References = The ISTQB Advanced Level Agile Technical Tester documents outline the importance of the FIRST principles in creating effective unit tests within Agile projects. These principles ensure that the tests are reliable and can be used in continuous integration and deployment processes12.
