Feature: junit formatter

  Background:
    Given passing

  Scenario: passing scenario
    Then passing

  Scenario: failing scenario
    When failing
    Then passing

  Scenario: pending scenario
    When pending
    Then passing

  Scenario: undefined scenario
    When undefined
    Then next undefined

  Scenario Outline: outline
    Given <one>
    When <two>

    Examples:
      | one     | two     |
      | passing | passing |
      | passing | failing |
      | passing | pending |

	Examples:
      | one     | two       |
      | passing | undefined |
