Test data: Boundary - GCSE Computer Science Definition

In computer science, 'Test data: Boundary' refers to a special kind of data used when testing programs or software. This data is chosen because it sits at the edges or the limits of what the program can handle. For example, if a program is designed to work with numbers from 1 to 100, boundary test data would include values like 1 and 100, as well as just outside that range, like 0 and 101. Testing with boundary data helps ensure that the program behaves correctly at its limits and can handle edge cases, preventing errors in everyday use. So, it’s an important step in making sure software is robust and reliable.
