GameOfLife

Code challenge for junior dev position March, 2017 By Jason Hinchcliffe

Instructions

• Unzip files
• Navigate to root directory
• Run ruby game_of_life.rb in terminal
• Press ctrl-c to exit the infinite loop

Evolution rules:

• Any live cell with fewer than two live neighbours dies, as if caused by underpopulation.
• Any live cell with two or three live neighbours lives on to the next generation.
• Any live cell with more than three live neighbours dies, as if by overpopulation.
• Any dead cell with exactly three live neighbours becomes a live cell, as if by reproduction.

Notes / Improvements

• The Neighbours method in Board needs refactoring - super ugly.
• Having a Cell class seemed unnecessary - board state just needs to have true / false for each section.
• In the Evolution test I'm requiring Board. Need to figure out how to test Evolution in isolation.
• Display isn't tested - not sure how to test text output to terminal.
