Feature: Todo List

Scenario: Adding an item to my todo list
  Given my todo list currently looks as follows:
  | TaskName            | Priority |
  | Fix bugs in my code | medium   |
  | Document my hours   | medium   |
  When I add the following task:
  | TaskName                              | Priority |
  | Watch cat videos on YouTube all day   | high     |
  Then I should see the following todo list:
  | TaskName                              | Priority |  
  | Watch cat videos on YouTube all day   | high     |
  | Sign up for unemployment              | high     |

	});
      });
