White-Box Testing

White-Box Testing is a software testing method where the tester has access to the internal workings, structure, and code of the application. It involves testing the system from the inside out, focusing on code logic, paths, and internal components to ensure correctness and optimize performance.

Key components of white-box testing include:

• Code Coverage: Ensuring that the code is thoroughly tested by executing all paths, branches, and conditions. This may include statement coverage, branch coverage, and path coverage.
• Internal Logic Testing: Verifying that the system’s internal logic and algorithms work as expected, ensuring all functions and methods are functioning properly.
• Unit Testing: Often used in white-box testing, unit testing involves testing individual units or components of the application (e.g., functions, methods, or classes) to ensure they work correctly.
• Security Testing: Checking for vulnerabilities in the code, such as buffer overflows, injection flaws, or improper access control, that could be exploited.
• Optimization: Identifying inefficient code, redundant operations, or bottlenecks that may impact system performance and proposing improvements.

White-box testing helps improve code quality, optimize performance, and identify hidden vulnerabilities by ensuring the internal logic and structure of the application are functioning as expected.
