Feature: Verifying emptiness

  As a Cucumber user
  I want a programmatic way to verify emptiness of a Mortadella instance
  So that I can verify the absence of data in comfortable ways.


  Scenario: an empty table
    Given I have a Mortadella instance:  "m = Mortadella.new headers: ['foo']"
    When I ask it whether it is empty:   "m.empty?"
    Then it responds with true


  Scenario: a non-empty table
    Given I have a Mortadella instance:  "m = Mortadella.new headers: ['foo']"
    And I add a data row:                "m << ['bar']"
    When I ask it whether it is empty:   "m.empty?"
    Then it responds with false
