Let’s test a simple program Here is a simple example from the paper on ‘An approach to Program Testing’ by J. C. Huang: © Sowmya Padmanabhan, 2003 3
Analysis To assert that the output value Z assumes the correct value for all input values of X and Y, we have to test all possible assignment values of X and Y. Suppose that X and Y take integer values and the program is tested on a computer whose word size is 32 bits. What is the maximum integer value that the program can take? © Sowmya Padmanabhan, 2003 4
