+Feature: LMS.Conditional Module
+  As a student, I want to view a Conditional component in the LMS
+
+  Scenario: A Conditional hides content when conditions aren't satisfied
+    Given that a course has a Conditional conditioned on problem attempted=True
+    And that the conditioned problem has not been attempted
+    When I view the conditional
+    Then the conditional contents are hidden
+
+  Scenario: A Conditional shows content when conditions are satisfied
+    Given that a course has a Conditional conditioned on problem attempted=True
+    And that the conditioned problem has been attempted
+    When I view the conditional
+    Then the conditional contents are visible
+
+  Scenario: A Conditional containing a Poll is updated when the poll is answered
+    Given that a course has a Conditional conditioned on poll poll_answer=yes
+    When I view the conditional
+    Then the conditional contents are hidden
+    When I answer the conditioned poll "yes"
+    Then the conditional contents are visible
