+Feature: Checkboxes Page
+
+  Background: Open Checkboxes page
+    Given I have navigated to the 'the-internet' "Checkboxes" page
+
+  Scenario: Verify Checkboxes page contents are correct
+    Then the page title is "Checkboxes"
+    And the page contains 2 checkboxes
+    And the checkbox labels are
+      | label      |
+      | checkbox 1 |
+      | checkbox 2 |
+    And the 1st checkbox is unchecked
+    And the 2nd checkbox is checked
+    And a "Fork me on GitHub" banner is displayed in the top-right corner of the page
+    And the page has a footer containing "Powered by Elemental Selenium"
+    And the link in the page footer goes to "http://elementalselenium.com/"
+
+  Scenario Outline: Click on <ordinal> checkbox
+    When I click on the <ordinal> checkbox
+    Then the <ordinal> checkbox is <state>
+    Examples:
+      | ordinal | state     |
+      | 1st     | checked   |
+      | 2nd     | unchecked |
+
+Scenario Outline: Click on <ordinal> checkbox twice
+  When I click on the <ordinal> checkbox
+  Then the <ordinal> checkbox is <first_state>
+  When I click on the <ordinal> checkbox
+  Then the <ordinal> checkbox is <second_state>
+  Examples:
+    | ordinal | first_state | second_state |
+    | 1st     | checked     | unchecked    |
+    | 2nd     | unchecked   | checked      |
