White-Box Testing (also known as Clear Box Testing, Glass Box Testing, or Structural Testing) is a software testing method where the internal structure, logic, and code of an application are tested. Testers have full knowledge of the system's code and design, which helps in verifying the correctness of code logic, pathways, and decision points.

• Involves testing code structures, algorithms, and internal functions
• Focuses on improving code efficiency, security, and logic
• Requires programming knowledge and access to the source code
