+Feature: LMS.Graphical Slider Tool Module
+  As a student, I want to view a Graphical Slider Tool Component
+
+  Scenario: The slider changes values on the page
+    Given that I have a course with a Graphical Slider Tool
+    When I view the Graphical Slider Tool
+    Then the displayed value should be 0
+    And I move the slider to the right
+    Then the displayed value should be 10
