 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:

Given that the shopper scans their card (the precondition),

When they checkout (the action),

Then they 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.

References = 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.

In the context of test-driven development (TDD), the next step after writing a failing test is to write the minimum amount of code necessary to make the test pass. This approach encourages simple designs and inspires confidence that the system is functioning as expected. Once the test passes, you can then refactor the code to improve its structure without changing its behavior.

References = The ISTQB Advanced Level Agile Technical Tester syllabus outlines the TDD process as a cycle of writing a failing test, making it pass, and then refactoring the code. This is a fundamental practice in Agile technical testing to ensure that the codebase remains clean and maintainable12.

 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.

References = 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.
