Classification trees are a visual way of identifying test objects and data, and pairwise testing is a technique of generating test cases that cover all possible pairs of values from different classifications. Classification trees support pairwise testing by:

• Helping to identify inputs to be used by the pairwise test technique, as each class represents a possible value for a test parameter.
• Showing the combinations needed to cover all-pairs, as each test case is a selection of one class from each classification.
• Helping to identify particular combinations of interest, as the test engineer can use the tree structure to group or prioritize classes based on their relevance or risk. References = ISTQB Advanced Level Test Analyst Syllabus 2019, section 3.2.3; Smarter Test Design with Classification Trees and Pairwise Techniques, slides 6-12.

Exhibit B is the only state transition diagram that matches the text description of Acme’s elevator door rules. It shows that the doors can transition between four states: Opened, Closing, Closed, and Opening. The transitions are triggered by either commands (open or close) or sensors (opened or closed). The diagram also shows that the open command can reverse the closing state, and the close command can reverse the opening state, as specified in the text. The other exhibits do not show the correct transitions or conditions for the elevator door system. References =

Functional appropriateness is the degree to which a product or system provides functions that meet stated and implied needs when used under specified conditions1. It is typically tested during system testing, which is the process of testing an integrated system to verify that it meets specified requirements2. System testing is conducted after component testing and before acceptance testing, and it covers both functional and non-functional aspects of the system3. References = ISO 25010, section A.1; ISTQB Advanced Level Test Analyst Syllabus 2019, section 1.3.1; Test Automation Fundamentals, section A.1.
