Codebreaker

A BDD command-line game built for The RSpec Book.

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                          # features/codebreaker_starts_game.feature:7
    Given I am not yet playing                  # features/step_definitions/codebreaker_starts_game_steps.rb:1
    When I start a new game                     # features/step_definitions/codebreaker_starts_game_steps.rb:4
    Then I should see "Welcome to Codebreaker!" # features/step_definitions/codebreaker_starts_game_steps.rb:9
    And I should see "Enter guess:"             # features/step_definitions/codebreaker_starts_game_steps.rb:9

Feature: code-breaker submits guess
  The code-breaker submits a guess of four numbers.  The game marks the guess
  with + and - signs.

  For each number in the guess that matches the number and position of a number
  in the secret code, the mark includes one + sign. For each number in the guess
  that matches the number but not the position of a number in the secret code,
  the mark includes one - sign.

  Each position in the secret code can only be matched once. For example, a
  guess of 1134 against a secret code of 1234 would get three plus signs: one
  for each of the exact matches in the first, third, and fourth positions. The
  number match in the second position would be ignored.

  Scenario Outline: submit guess      # features/codebreaker_submits_guess.feature:16
    Given the secret code is "<code>" # features/codebreaker_submits_guess.feature:17
    When I guess "<guess>"            # features/codebreaker_submits_guess.feature:18
    Then the mark should be "<mark>"  # features/codebreaker_submits_guess.feature:19
