Scenario: All steps passing means the scenario passes
  Given a scenario "Basic Arithmetic" with:
    """
    When I add 4 and 5
    Then the result is 9
    """
  When Cucumber executes "Basic Arithmetic" with these step mappings:
    | I add 4 and 5   | passing |
    | the result is 9 | passing |
  Then the scenario passes

# becomes:

Scenario: All steps passing means the scenario passes
  Given a scenario "Basic Arithmetic" with:
    """
    When I add 4 and 5
    Then the result is 9
    """
  And the step "I add 4 and 5" maps to "passing"
  And the step "the result is 9" maps to "passing"
  When Cucumber executes the scenario "Basic Arithmetic"
  Then the scenario passes

# or even:

Scenario: All steps passing means the scenario passes
  Given a scenario "Basic Arithmetic" with:
    """
    When I add 4 and 5
    Then the result is 9
    """
  And the step "I add 4 and 5" maps to a passing definition
  And the step "the result is 9" maps to a passing definition
  When Cucumber executes the scenario "Basic Arithmetic"
  Then the scenario passes
