Cucumber implementation-independent feature ideas

basic.feature

Feature: Basic feature execution
  In order to do BDD
  As a cucumber afficionado
  I want to run basic cucumber features

  # 1. Not abstract enough: first step is language dependent
  Scenario: Simple flat steps
    Given the following step definition:
      """
      When(/a step passes/, function()  {
        callback();
      });
      """
    When I run the following feature:
      """
      Feature: Simple flat steps
        Scenario: Simple flat step
          When a step passes
      """
    Then the feature should have run successfully

  # 2. Language dependence is gone, that's better. But specifying a
  #    whole feature source each time seems a bit redundant between
  #    scenarios.
  Scenario: Simple flat steps
    Given a step definition matching /a step passes/
    When I run the following feature:
      """
      Feature: Simple flat steps
        Scenario: Simple flat step
          When a step passes
      """
    Then the feature should have run successfully

  # 3. Redundancy between scenarios is gone and the useful statement
  #    from step 2 (i.e. the name of the called step) is not lost.
  #    Note: I didn't include the "When" keyword in the name of the 
  #    step for briefness, it could be there of course.
  Scenario: Simple flat steps
    Given a step definition matching /a step passes/
    When I run a feature with a step called "a step passes"
    Then the feature should have run successfully

  # 4. Highest level of abstraction.
  Scenario: Simple flat steps
    Given a passing step definition
    When I run a feature using the step definition
    Then the feature should have run successfully
