What is the focus of structural testing?

Structural testing, often referred to as white-box testing, focuses on the internal structure of the software application. This involves reviewing the system architecture and design to ensure that the implementation aligns with the intended framework and logic. The goal is to verify that the software components work correctly together, examining how individual pieces interact and contribute to overall functionality.

By concentrating on the architecture and design, structural testing provides insights into the internal workings of the system, allowing testers to identify any flaws or inefficiencies in the code itself. This method contrasts with other forms of testing, which may prioritize user interaction or requirements without assessing how those interactions are managed within the system. Through this detailed examination of structure and design, structural testing helps ensure that the system is robust and reliable before it is validated against end-user expectations.
