Background:

An online bookstore application allows users to browse, search for, and purchase books. The

application features user account creation and management, a search engine for books, a shopping

cart, and a checkout system with payment processing.

Scenario:

The development team has recently introduced a new feature: personalized book

recommendations. This feature analyzes the user's past purchases and browsing history to

recommend books. The team has also updated the search engine to include filters based on book

genres, author names, and publication dates.
