Approach

Design Approach

1. Follow the extreme programming approach. Write test first and then let it fails write minimal code to pass then refactor it and again check if it pass. Then write next test and so on.

2. Divide the problem into separate concerns:

• lib/web_log_parser/web_log_file.rb: Responsible for reading the content and validating the file.
• lib/web_log_parser/page_views.rb: Responsible for creating a data structure so I can get page visits and unique view efficiently.
• lib/web_log_parser/view.rb: Responsible for showing the view.
• lib/web_log_parser.rb: Responsible for being a single interface to build all object and perform the operation.

What can be improved

• Naming. Like page views and views.
• View class can be write better so I dont have to pass the block for page visits an unique view.
