+Feature: Hovercards
+  In order to not having to leave the page to view a persons profile
+  As a user
+  I want to use hovercards
+
+  Background:
+    Given a user named "Bob Jones" with email "bob@bob.bob"
+    And "bob@bob.bob" has a public post with text "public stuff"
+    And a user named "Alice" with email "alice@alice.alice"
+    And I sign in as "alice@alice.alice"
+
+
+  Scenario: Hovercards on the main stream
+    Given I am on "bob@bob.bob"'s page
+    Then I should see "public stuff" within ".stream_element"
+    When I activate the first hovercard
+    Then I should see a hovercard
+    When I deactivate the first hovercard
+    Then I should not see a hovercard
