Which testing method leverages internal software knowledge to select data?

The chosen answer, which refers to white-box testing, signifies a testing method that utilizes knowledge of the internal workings or structure of the software. In this testing approach, testers have access to the source code, design documents, and other internal details, allowing them to craft test cases that are more targeted and informed. This enables the selection of specific data inputs that can effectively validate the handling of various scenarios within the system.

White-box testing is particularly advantageous for identifying logical errors and vulnerabilities in the code since testers can directly analyze the internal paths and structures. Because of this in-depth knowledge, white-box testing allows for comprehensive assessments of the software's functionalities, ensuring that all code paths are tested and aiding in verifying the system's performance under different conditions.

Understanding the software's internal architecture empowers testers to make informed decisions about what data to use during testing, directly contributing to the overall quality assurance process.
