1.Consider a Web site that allows its visitors to search for items in a database using arbitrary search strings. Suppose we focus our attention only on three operations allowed by this site: search, previous, and next. To invoke the search operation, a search string is typed and the Go button clicked. When the search results are displayed, the Previous and Next buttons show up and may be clicked to move to the next or the previous page of search results. Describe how an oracle will determine whether or not the three functions of the Web site are implemented correctly. Can this oracle be automated ?(20points) 1.Consider a Web site that allows its visitors to search for items in a database using arbitrary search strings.
