Which type of test is commonly used in the early phases of system development?

• A. Integration testing
• B. Unit testing
• C. Developmental testing
• D. System testing

Answer: (C)

Developmental testing is a critical activity in the early phases of system development. This type of testing is primarily focused on verifying that the components of a system, including hardware and software, function as intended and meet specified requirements. It allows teams to identify and address issues early in the development process, which can significantly reduce the costs and risks associated with later-stage testing and integration. During developmental testing, prototypes or initial versions of the system are evaluated to ensure that they meet the design specifications and can operate effectively within their intended environment. It often involves a combination of unit testing and integration testing, but its primary focus is on validating that the overall development goals are being met. In contrast, integration testing typically occurs after the individual components have been verified and focuses on how different parts of the system work together. Unit testing is aimed at testing the smallest parts of the system in isolation. System testing assesses the complete and integrated software system to ensure that it meets specified requirements, occurring later in the development lifecycle after developmental testing has been conducted.
