test objects design

Another example why you need to test your web application for error handling. This is from Jim Carr at eCommerce Business and I quote “Barnes & Noble.com’s appear instead to nail the poor beast to the highway, leaving it as roadkill. At least, that’s how I felt after ordering a book — and not receiving it for almost three weeks — from the No. 2 online bookseller. My problems started from the get-go. When prompted to enter my gift-certificate number at the bn.com shopping cart, I apparently typed the wrong number. (The certificate contains separate “serial” and “verification” numbers.) This left bn.com’s back-end systems unable to process my order.”
