-@shard_2
-Feature: CMS.Course updates
-    As a course author, I want to be able to provide updates to my students
-
-    # Internet explorer can't select all so the update appears weirdly
-    @skip_internetexplorer
-    Scenario: Users can change handouts
-        Given I have opened a new course in Studio
-        And I go to the course updates page
-        When I modify the handout to "<ol>Test</ol>"
-        Then I see the handout "Test"
-        And I see a "saving" notification
-
-    Scenario: Static links are rewritten when previewing handouts
-        Given I have opened a new course in Studio
-        And I go to the course updates page
-        When I modify the handout to "<ol><img src='/static/my_img.jpg'/></ol>"
-        # Can only do partial text matches because of the quotes with in quotes (and regexp step matching).
-        Then I see the handout image link "my_img.jpg"
-        And I change the handout from "/static/my_img.jpg" to "<img src='/static/modified.jpg'/>"
-        Then I see the handout image link "modified.jpg"
-        And when I reload the page
-        Then I see the handout image link "modified.jpg"
-
-    Scenario: Users cannot save handouts with bad html until edit or update it properly
-        Given I have opened a new course in Studio
-        And I go to the course updates page
-        When I modify the handout to "<p><a href=>[LINK TEXT]</a></p>"
-        Then I see the handout error text
-        And I see handout save button disabled
-        When I edit the handout to "<p><a href='https://www.google.com.pk/'>home</a></p>"
-        Then I see handout save button re-enabled
-        When I save handout edit
-        # Can only do partial text matches because of the quotes with in quotes (and regexp step matching).
-        Then I see the handout "https://www.google.com.pk/"
-        And when I reload the page
-        Then I see the handout "https://www.google.com.pk/"
