Functional testing is an example of black-box dynamic testing. Functional testing is the process of testing the functionality or behavior of a software system based on its requirements or specifications. Functional testing does not require any knowledge of the internal structure or implementation of the system under test; it only focuses on what the system does rather than how it does it. Functional testing is also an example of dynamic testing because it involves executing the software system with selected inputs and observing its outputs and effects on the environment. Dynamic testing is different from static testing, which involves examining the software system without executing it, such as code inspection, static analysis, etc. You can find more information about functional testing and dynamic testing in A Study Guide to the ISTQB® Foundation Level 2018 Syllabus, Chapter 21.

The correct answer is D, as it describes exploratory testing. Exploratory testing is an experience-based test technique that involves simultaneous learning, test design, and test execution1. Exploratory testing may be used within defined time periods, during which the tester may follow a test charter as a guide. A test charter is a document that specifies the scope, objective, and approach of an exploratory testing session1. Option A is incorrect, as exploratory testing is not a suitable test technique that may replace both black-box and white-box test techniques, but a complementary technique that can be used along with other techniques1. Option B is incorrect, as exploratory testing does not require both solid specifications and much project time available for test execution, but can be used in situations where specifications are incomplete or changing and where time is limited1. Option C is incorrect, as exploratory testing is not a valid and useful black-box test technique since it focuses on test cases related to the architecture and design of a system, but an experience-based test technique that focuses on learning about the system and its behavior1.

A requirements management tool may be considered as a test support tool because it can help support or enhance some aspects of testing activities or processes. A requirements management tool is a tool that allows users to manage and trace the requirements of a software system. A requirements management tool can help support or enhance testing activities or processes by:

• Providing a clear and consistent definition of what needs to be tested based on user needs and expectations
• Enabling traceability between requirements and test cases to ensure adequate and complete test coverage
• Supporting change management and impact analysis by identifying and tracking changes in requirements and their effects on testing activities and results

 System integration testing and acceptance testing are two different levels of testing that have different objectives and stakeholders. System integration testing is the process of testing the interactions and interfaces between different components or systems that form a larger system. System integration testing verifies that the system meets its functional and non-functional requirements and works as expected in its intended environment. System integration testing is usually done by testers or developers who have access to the system architecture and design specifications. Acceptance testing is the process of testing the system by the end users or customers to determine if it satisfies their needs and expectations and is ready for deployment or delivery. Acceptance testing verifies that the system complies with the user requirements and business processes and provides value to the stakeholders. Acceptance testing is usually done by users or customers who have access to the user requirements and business scenarios. You can find more information about system integration testing and acceptance testing in A Study Guide to the ISTQB® Foundation Level 2018 Syllabus, Chapter 2, Sections 2.2 and 2.31.

Test metrics are quantitative measures that are used to monitor, control, and improve the test process and its outcomes. Test metrics can be collected at different levels of testing (test case, test suite, test project, etc.) and can be used for different purposes (planning, estimation, execution, evaluation, etc.). Some examples of common test metrics are:

• Percentage of work done in test environment creation: This metric indicates how much effort has been spent on setting up and maintaining the test environment, which includes hardware, software, network, data, tools, etc., that are required for conducting the test activities.
• Number of test cases run: This metric indicates how many test cases have been executed during a given period or phase of testing.
• Deviation from test milestone dates: This metric indicates how much delay or ahead of schedule the test activities are compared to the planned dates.
• Defect density: This metric indicates how many defects have been found per unit of size or functionality of the system under test.

Average number of expected defects per requirement is not a common test metric because it is not easy to estimate or measure how many defects are likely to be found for each requirement. Moreover, this metric does not provide useful information for improving the test process or evaluating the test results. You can find more information about test metrics in A Study Guide to the ISTQB® Foundation Level 2018 Syllabus, Chapter 5, Section 5.41.

Component testing is a part of the V-Model, which is a development life cycle model that shows the relationship between each phase of development and its corresponding phase of testing. In this model, each level of testing (unit testing, integration testing, system testing, acceptance testing) has a corresponding level of development (component design, component integration, system design, requirements analysis). Component testing is the process of testing individual components or units of software in isolation from other components or systems. Component testing verifies that the components meet their functional and non-functional requirements and work as expected in their intended environment. Component testing is usually done by developers who have access to the component design and code specifications. You can find more information about component testing and the V-Model in Software Testing Foundations: A Study Guide for the Certified Tester Exam, Chapter 22.

A configuration management tool is a tool that allows users to manage and control the versions and changes of software artifacts, such as code, documents, test cases, etc. A configuration management tool can help prevent the loss of Sam’s updates by:

• Providing a centralized repository where Sam can store and retrieve his test cases and other artifacts
• Keeping track of the history and status of each artifact and allowing Sam to compare and revert to previous versions if needed
• Supporting collaboration and communication among team members by allowing them to share and access the latest versions of the artifacts

The other tools mentioned in the question are not relevant for this scenario because they do not provide the same functionality or benefits as a configuration management tool. For example:

• A. Incident management tool: This tool type allows users to record, track, manage, and report the defects found during testing. It does not help with managing or controlling the versions or changes of test cases or other artifacts.
• C. Test execution tool: This tool type allows users to execute test cases automatically or semi-automatically and compare the actual results with the expected results. It does not help with managing or controlling the versions or changes of test cases or other artifacts.
• D. Backup tool: This tool type allows users to create copies of data or files and store them in a different location or device for recovery purposes. It does not help with managing or controlling the versions or changes of test cases or other artifacts.

You can find more information about configuration management tools in [A Study Guide to the ISTQB® Foundation Level 2018 Syllabus], Chapter 6, Section 6.4.

Static analysis tools are tools that examine the code or design of a software system without executing it. Static analysis tools can be used to find defects, measure complexity, check compliance, or improve quality. Some examples of defect types that can be found by static analysis tools are:

• Variables that are never used: This defect type occurs when a variable is declared but not referenced or assigned in the code, which indicates a waste of memory or a logic error.
• Coding standard violations: This defect type occurs when the code does not follow the predefined rules or conventions for formatting, naming, commenting, etc., which affects the readability and maintainability of the code.
• Uncalled functions and procedures: This defect type occurs when a function or procedure is defined but not called or invoked in the code, which indicates a waste of resources or a missing functionality.

Memory leaks are defect types that are least likely to be found by static analysis tools because they are related to the dynamic behavior and performance of the software system. Memory leaks occur when a program does not release memory that it has allocated, causing the system to run out of memory and slow down or crash. Memory leaks can only be detected by dynamic analysis tools that monitor the memory usage of the program during execution. You can find more information about static analysis tools in [A Study Guide to the ISTQB® Foundation Level 2018 Syllabus], Chapter 6, Section 6.3.
