Feature: Detect Palindromes

As a user I want to be able to check if a given word or phrase is a palindrome.

Scenario Outline: Provide input to palindrome?
  Given the input "<input>"
  When palindrome? is run
  Then the output should be "<output>"
  
Examples:
  |input|output|
  |A man, a plan, a canal -- Panama|true|
  |Madam, I'm Adam!|true|
  |Abracadabra|false|

Feature: Detect Palindromes

  As a user I want to be able to check if a given word or phrase is a palindrome.

  Scenario Outline: Provide input to palindrome? # features\palindrome.feature:5
    Given the input "<input>"                    # features\palindrome.feature:6
    When palindrome? is run                      # features\palindrome.feature:7
    Then the output should be "<output>"         # features\palindrome.feature:8

    Examples:
      | input                            | output |
      | A man, a plan, a canal -- Panama | true   |
      | Madam, I'm Adam!                 | true   |

You can implement step definitions for undefined steps with these snippets:

Given /^the input "([^"]*)"$/ do |arg1|
  pending # express the regexp above with the code you wish you had
end

When /^palindrome\? is run$/ do
  pending # express the regexp above with the code you wish you had
end

Then /^the output should be "([^"]*)"$/ do |arg1|
  pending # express the regexp above with the code you wish you had
end

If you want snippets in a different programming language,
just make sure a file with the appropriate file extension
exists where cucumber looks for step definitions.
