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.

A tool type is a category of tools that have similar features and functions and can be used for similar purposes. A test manager is a person who is responsible for planning, monitoring, controlling, and reporting the test activities and results. A test manager needs to use tools that can help them with these tasks and provide them with useful information and insights. Some examples of tool types that are useful for a test manager are:

• Defect tracking tool: This tool type allows the test manager to record, track, manage, and report the defects found during testing. It also helps the test manager to communicate with developers, testers, and other stakeholders about the defect status and resolution.
• Test management tool: This tool type allows the test manager to organize, manage, and control the test process and its outcomes. It also helps the test manager to define the test strategy, plan the test activities, allocate the test resources, schedule the test execution, monitor the test progress, and evaluate the test results.
• Requirements management tool: This tool type allows the test manager to manage and trace the requirements of the system under test. It also helps the test manager to ensure that the test objectives are aligned with the user needs and expectations and that the test coverage is adequate and complete.

The other tool types mentioned in the question are not as useful for a test manager as they are for other roles or purposes. For example:

• Modeling tool: This tool type allows the user to create graphical or textual representations of software systems or processes. It can be used for design, analysis, simulation, or documentation purposes.
• Static analysis tool: This tool type allows the user to examine the code or design of a software system without executing it. It can be used for finding defects, measuring complexity, checking compliance, or improving quality.
• Coverage measurement tool: This tool type allows the user to measure how much of the code or design of a software system has been exercised by a set of test cases. It can be used for evaluating the effectiveness or completeness of testing.

Regression testing is a type of testing that is performed after a software system has been changed or modified to verify that the changes have not introduced any new defects or adversely affected the existing functionality of the system. Regression testing can be performed when the software system undergoes different types of changes, such as:

• Corrective changes: Changes that fix defects or errors in the software system
• Adaptive changes: Changes that adapt the software system to new platforms or environments
• Perfective changes: Changes that improve the performance or usability of the software system
• Preventive changes: Changes that avoid potential problems or issues in the software system

In this case, the software system was re-deployed because the backend database was changed from one vendor to another, which is an example of an adaptive change. Therefore, the test manager decided to perform some functional tests on the re-deployed system to ensure that the change did not affect the functionality of the system. This is an example of regression testing.

The other types of testing mentioned in the question are not relevant for this scenario. For example:

• Non-functional testing: This type of testing verifies the non-functional aspects of the software system, such as reliability, performance, security, usability, etc.
• Structural testing: This type of testing verifies the internal structure or implementation of the software system, such as code, architecture, design, etc.
• Unit testing: This type of testing verifies individual components or units of software in isolation from other components or systems.

Testing has several objectives that aim to provide information and confidence about the quality and risk level of the software product and to support decision-making and improvement processes. Some of these objectives are:

• Finding defects: Testing is the process of finding defects or failures in the software product that do not meet its requirements or expectations.
• Providing information for decision-making: Testing is the process of providing information about the quality and risk level of the software product based on the observed behavior and results under certain conditions and assumptions. This information can help stakeholders make informed decisions about releasing, deploying, accepting, or improving the software product.
• Gaining confidence about the level of quality of the software: Testing is the process of gaining confidence that the software product meets its requirements and expectations and provides value to the users and customers.
• Analyzing and removing the cause of failures: Testing is not only the process of finding defects but also the process of analyzing and removing the cause of failures that lead to defects. This objective is related to debugging, which is a development activity that involves locating, diagnosing, and fixing errors in the code or design of the software product.
