Feature: Configuration from config.d
  Background:
    Given a directory named "templates"
    And a file named "templates/test.erb" with:
    """
    Test var : <%= test_var %>
    """
    And a file named "templates/additional.erb" with:
    """
    Additional var : <%= additional_var %>
    """
    And a directory named "config.d"

  Scenario: Override common.yaml
    Given a file named "common.yaml" with:

  Scenario: Configuration from 3 separate files
    Given a file named "config.d/00-base.yaml" with:
