Approach
-
Planning: Focusing on agile and Object Orientated Design, I broke down the specification into smaller issues to write user stories. Domain modelling enabled me to identify 'noun' and 'verb' relationships. Diagramming aided in visualising my thought process.
-
Test Driven Development: TDD ensured I made logical design decisions and allowed me to identify bugs to be solved quickly. I was not able to test for everything i.e. PokerGame#play however this is something I would like to be worked on in the future.
All tests pass!
- Refactoring: Refactoring as I went along to ensure that my code was as clean as possible. There are still a couple things I would like to work on such as SRP with the classes and methods.
