Week 2 – More OOP, class extraction and dependency injection

This week was a continuation and consolidation of the OOP, ODD, Ruby and TDD topics covered in week 1.

The weekly challenge was Oystercards: a TDD Ruby sim of London’s Oystercard system.  The weekend challenge was to create a very basic takeaway ordering system that sent a confirmation text message using Twilio.  Again, this was done with TDD Ruby.
