 S2 and O2 are the finishing state and the output(s) from the test case1. The question asks about a test case that starts at S1 and triggers 4 events in sequence: E1, E4, E5, E7. The question refers to a state diagram that shows the logic of a system with six states (S1, S2, S3, S4, S5, S6) and seven events (E1, E2, E3, E4, E5, E6, E7). The state diagram also shows four outputs (O1, O2, O3, O4) that are produced by some events. The state diagram is shown below:

To answer this question, we need to follow the path of the test case on the state diagram and observe the state transitions and outputs that occur. The path of the test case is:

• Start at S1
• Trigger E1
• Transition to S2
• Trigger E4
• Transition to S3
• Trigger E5
• Transition to S2
• Output O2
• Trigger E7
• Transition to S6

Therefore, the finishing state of the test case is S2 and the output(s) from the test case is O2. Hence, D is the correct answer.

A white box testing design technique is D. Statement testing. Statement testing is a white box testing technique that is based on an analysis of the structure of the component or system. Statement testing aims to cover every executable statement in the code at least once by the test cases. Statement testing can help to detect syntax errors, logic errors, or unreachable code in the system or component under test. Statement testing is usually performed at lower levels of testing, such as unit testing or component testing. A detailed explanation of statement testing can be found in [A Study Guide to the ISTQB® Foundation Level 2018 Syllabus], pages 68-69.

Statement testing is part of structure-based testing, which is a type of testing that verifies the internal structure or implementation of a software system, such as code, architecture, design, etc. Statement testing is a structure-based test technique that involves testing every statement in the code at least once to ensure that there are no syntax errors, logical errors, or hidden defects in the code. Statement testing requires some knowledge of the internal structure or implementation of the software system; it focuses on how the system does what it does rather than what it does.

The other types of testing mentioned in the question are not related to statement testing because they do not verify the internal structure or implementation of a software system. For example:

• A. Experience-based testing: This type of testing relies on the skills, knowledge, intuition, and creativity of testers to design and execute test cases based on their experience with similar systems or situations.
• B. Decision testing: This type of testing verifies every decision point in the code by testing all possible outcomes or branches of each decision point to ensure that there are no logical errors or hidden defects in the code.
• C. Specification-based testing: This type of testing verifies the external behavior or functionality of a software system based on its requirements, specifications, design documents, or other sources of information.
