Feature: Tagging test cases for uniqueness

  Tests are tagged based on a simple <prefix><unique_id> pattern. Every test gets a tag at the test level and, in the case outlines, a sub-id for each of its example rows. Any test which has already been given an id tag or other id information will not have that information modified by the tagging process.


  Background:
    * a tag prefix of "@test_case_"


  Scenario: Tagging tests that don't have id tags

  This is one of the most common cases, wherein new tests have been written but they have not yet been tagged by the tagging tool.

  Scenario: Tagging outlines that are partially 'filled in'

  Whereas scenarios either have an id tag or don't, outlines have many more places for identifying information to be placed and it is quite possible that some of that information is already present. Maybe several scenarios were combined into one outline and an id tag got carried over. Maybe an extra row or entire example table was added to an already tagged outline. Maybe someone removed id information by accident. In any case, the missing information is replaced by the tagging tool.
