Work Breakdown Structure (WBS) is a project management technique that decomposes a project into smaller and manageable tasks. It is not a factor that is used as a basis for estimating testing effort, but rather an outcome of the estimation process. The other options are factors that can influence the testing effort, such as the quality of the test basis, the requirements for documentation, and the skills of the test team.

Integration testing is the process of testing the interactions between different components or subsystems of a system. It has the following characteristics:

• It can be done in an incremental manner, meaning that components or subsystems are integrated and tested one by one until the whole system is integrated and tested.
• It is usually done before system testing, which is the process of testing the system as a whole against its requirements and specifications.
• It includes functional tests, which are tests that verify the functionality and behavior of the system or its components.
• It includes non-functional tests, which are tests that verify the quality attributes of the system or its components, such as performance, reliability, security, etc.

Therefore, statements I, III, and IV are correct.

Preventing defects from being introduced into the code is not a valid objective of testing, because testing can only detect defects that are already present in the code, not prevent them from happening. Testing can help prevent future defects by providing feedback to developers and other stakeholders, but it cannot guarantee that no defects will be introduced. Preventing defects is more related to quality assurance activities, such as reviews, inspections, and standards12.

Functional and structural testing can both be applied at all test levels, from component testing to acceptance testing1 . Functional testing verifies whether the software meets the specified requirements and user expectations, while structural testing verifies whether the software meets the specified design and code standards1 . Both types of testing can be useful at any stage of the software development life cycle, depending on the test objectives and scope1 . The other options are incorrect, because they limit the application of functional and structural testing to certain test levels only.
