+Feature: Question submission and answering will follow the availability setting
+  In order to allow users to submission questions or answering questions only in a limited period
+  As a teacher
+  I need availability setting for question submission and question answering
+
+  Background:
+    Given the following "courses" exist:
+      | fullname | shortname | category |
+      | Course 1 | C1        | 0        |

+      | studentquiz | StudentQuiz Test | StudentQuiz description | C1     | studentquiz1 |
+    And the following "questions" exist:
+      | questioncategory             | qtype     | name       |
+      | Default for StudentQuiz Test | truefalse | Question 1 |
+      | Default for StudentQuiz Test | truefalse | Question 2 |
+      | Default for StudentQuiz Test | truefalse | Question 3 |
+
+  @javascript
+  Scenario: New availability settings should exist
+    Given I log in as "admin"
+    And I am on "Course 1" course homepage
+    And I turn editing mode on
+    And I add a "StudentQuiz" to section "1"
+    When I expand all fieldsets

+    And I expand all fieldsets

+
+    # Submissions deadline can not be specified before the open for submissions date
