Computer Science for IGCSE & O level - Algorithm Design And Problem Solving (Section 7 - No. 47)
What is the role of 'boundary data' during algorithm testing?
To check how the algorithm processes numbers near the extreme range (boundaries) of acceptable inputs.
To provide average input values to see how the algorithm performs in normal circumstances.
To verify that the algorithm does not produce output outside the defined range.
To test every branch.
Forklaring
Boundary data checks the extremes of acceptable inputs to identify potential errors.
