Cucumber(2): puts, raw, diff!

說明

puts: 顯示數據
raw: 將數據表轉換成陣列
diff!: 比較數據表

建立 test_board.feature

# test_board.feature
Feature: Test board
Background: Some backgrounds here
Scenario: Add row and column
    Given a board like this:
    |    | 1 | 2 | 3 |
    | 1 |    |    |    |
    | 2 | x |    |    |
    | 3 |    |    |    |
    When player x plays in row 3, column 2
    Then the board should look like this:
    |    | 1 | 2 | 3 |
    | 1 |    |    |    |
    | 2 | x |    |    |
    | 3 |    | x |    |

建立 steps.rb

# features/step_definitions/steps.rb

Given /^a board like this:$/ do |table|
    @board = table.raw
end

When /^player x plays in row (\d+), column (\d+)$/ do |row, col|
    row, col = row.to_i, col.to_i
    @board[row][col] = 'x'
    puts @boards
end

Then /^the board should look like this:$/ do |expected_table|
    expected_table.diff!(@board)
end
