+Feature: Extensions
+  In order to have an open source ecosystem for stylesheets
+  As a compass user
+  I can install extensions that others have created
+  And I can create and publish my own extensions
+
+  Scenario: Extensions directory for stand_alone projects
+    Given I am using the existing project in test/fixtures/stylesheets/compass
+    And the "extensions" directory exists
+    And and I have a fake extension at extensions/testing
+    When I run: compass --list-frameworks
+    Then the list of frameworks includes "testing"
+
+  Scenario: Extensions directory for rails projects
+    Given I'm in a newly created rails project: my_rails_project
+    And the "my_rails_project/vendor/plugins/compass/extensions" directory exists
+    And and I have a fake extension at my_rails_project/vendor/plugins/compass/extensions/testing
+    When I run: compass --list-frameworks
+    Then the list of frameworks includes "testing"
