Confirmation testing, also known as re-testing, is the process of testing a defect that has been fixed to verify that it has been resolved and does not affect other parts of the system. Confirmation testing is usually done by the same tester who reported the defect and using the same test case that revealed the defect. You can find more information about confirmation testing in A Study Guide to the ISTQB® Foundation Level 2018 Syllabus, Chapter 3, Section 3.21.

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

The V-model 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). The model also shows that testing activities should start as early as possible in the development process and that each level of testing should be planned and designed in parallel with its corresponding level of development. Therefore, one of the roles of a tester in a software company that adopts the V-model is to coordinate the test strategy with the project managers who are responsible for planning and managing each phase of development. This role involves defining the scope, objectives, approach, resources, schedule, risks, and deliverables of each level of testing in alignment with the development plan and the project requirements. You can find more information about the V-model and test planning in Software Testing Foundations: A Study Guide for the Certified Tester Exam, Chapter 22.

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.
