property.feature

@hp
Property: HP
  HP stands for health points and denotes whether an entity is alive or 
  dead.
  
  @valid
  Given HP
   When valid
   Then it must be a natural number 
    And greater than or equal to 0 
    And less than or equal to 100

@entity
Property: Entity 
  Entity stands for any character; friend or foe 

  @an@another
  Given an entity 
   Then it can be any of below:
   |Hero|
   |Damsel in distress|
   |Monster|

  @dead@died
  Given an entity
   When dead
   Then it has 0 @hp

Scenario Outline: Every @entity shall inevitably die
  Given I have @an @entity: A with @valid @hp
    And I have @another @entity: B with @valid @hp
   When A strikes B
   Then the @hp of B will decrement by 1
    And B will continue to be struck until it has @died
