Cucumber

What is cucumber?

Cucumber example

Feature: code-breaker starts game

          As a code-breaker

          I want to start a game

          So that I can break the code

Scenario: start game

          Given I am not yet playing

          When I start a new game

          Then the game should say “Welcome to CodeBreaker”

          And the game should say “Enter guess:”
