Activity Description

This activity must be solved individually or in pairs.

Write a web application that allows testing the user about her/his knowledge on design patterns. The application must allow the user to select how many questions (between one and ten) she/he wants to answer. The questions must be selected randomly from a bank of at least 30 multiple choice items. All questions must be related to design patterns or antipatterns, and must be taken from any of the following resources: [OLSEN], [GAMMA] or [SOURCEMAKING].

Each question should appear by itself in its own page. Once the user answers the question, the application must give the user the corresponding feedback, indicating if the answer was right or wrong, and displaying the correct answer if the user’s choice was wrong. Once all questions have been answered, the application must display the final score, and give the user the option to restart it.

The application must be developed using the Ruby programming language, the Sinatra DSL, and the SQLite RDBMS via the Active Record design pattern. The user interface must be intuitive and easy to use.
