+Feature: oembed
+  In order to make videos easy accessible
+  As a user
+  I want the links in my posts be replaced by their oEmbed representation
+
+  Background:
+    Given a user named "Alice Smith" with email "alice@alice.alice"
+    And I have several oEmbed data in cache
+    When I sign in as "alice@alice.alice"
+    And I am on the home page
+
+  Scenario: Post a secure video link
+    Given I expand the publisher
+    When I fill in "status_message_fake_text" with "http://youtube.com/watch?v=M3r2XDceM6A&format=json"
+    And I press "Share"
+
+    And I follow "Your Aspects"
+    Then I should see a video player
+
+  Scenario: Post an unsecure video link
+    Given I expand the publisher
+    When I fill in "status_message_fake_text" with "http://mytube.com/watch?v=M3r2XDceM6A&format=json"
+    And I press "Share"
+
+    And I follow "Your Aspects"
+    Then I should not see a video player
+    And I should see "http://mytube.com/watch?v=M3r2XDceM6A&format=json"
+
+  Scenario: Post an unsecure rich-typed link
+    Given I expand the publisher
+    When I fill in "status_message_fake_text" with "http://myrichtube.com/watch?v=M3r2XDceM6A&format=json"
+    And I press "Share"
+
+    And I follow "Your Aspects"
+    Then I should not see a video player
+    And I should see "http://myrichtube.com/watch?v=M3r2XDceM6A&format=json"
+
+  Scenario: Post a photo link
+    Given I expand the publisher
+    When I fill in "status_message_fake_text" with "http://farm4.static.flickr.com/3123/2341623661_7c99f48bbf_m.jpg"
+    And I press "Share"
+
+    And I follow "Your Aspects"
+    Then I should see a "img" within ".stream_element"
+
+  Scenario: Post an unsupported text link
+    Given I expand the publisher
