Chapter 9, Problem 94H

“Untitled.” by Stephen Chen

lye often wondered how software is released and sold to the public. ironically, I work foi a company that sells products with knoisii problems. Unfortunately, most of the problems aze difficult to c,eate, which makes them difficult to fbc. I usually use the test program X, which tests the product, to ny to create a specific problem. When the test program Is run ro make an error occur, the likelihood of generating an error Is 1%.

So, aimed with this knowledge, I wrote a new test program Y that will generate the same error that test program X creates, but more often. To find out If m test program Is better than the original, so that I can convince the management that [m right, I ran my test piogram to find out how often I can generate the same error. When I ran my test program 50 times, I generated the error twice. While this may not seem much better, I chink that I can convince the management to use my test program instead of the original test program. Am I right?
