| White-box refers to a situation where the internal workings, structures, or components of a system are known and visible to the observer. | Black-box refers to a situation where the internal workings, structures, or components of a system are unknown or hidden from the observer. |
| White-box refers to a situation where the internal workings, structures, or components of a system are known and visible to the observer. | It focuses on understanding and analyzing the system’s behavior and outputs without knowledge of its internal mechanisms. |
| In a white-box approach, the person or analyst has access to the internal code, architecture, and design of the system being studied or tested. | In a black-box approach, the person or analyst has no knowledge or access to the internal code, design, or architecture of the system. |
| The white-box approach assumes prior knowledge of the internal workings, which enables a deeper understanding of how the system operates. | The black-box approach assumes no prior knowledge of the internal workings, requiring the observer to rely solely on the inputs and outputs of the system. |
| In software testing, white-box testing involves examining the internal logic, code coverage, and data flows to ensure the system functions as intended. | In software testing, black-box testing involves examining the system’s functionality, behavior, and user experience without considering the internal implementation. |
| White-box provides transparency and allows for detailed analysis, debugging, and optimization of the system. | Black-box provides independence from the internal complexities, allowing for a more user-centric or high-level perspective on the system. |
