+    Given I am on the "Music history" "workshop activity" page logged in as teacher1
+    When I change phase in workshop "Music history" to "<phase>"

+      | Grading evaluation phase |
+      | Closed                   |
+
+  Scenario: Filter submissions report by surname/first name is hidden in the Setup phase.

+  Scenario: Filter submissions report by surname name as a teacher.
+    Given I am on the "Music history" "workshop activity" page logged in as teacher1
+    And I change phase in workshop "Music history" to "Submission phase"
+    When I click on "V" "link" in the ".lastinitial" "css_element"

+    When I click on "V" "link" in the ".firstinitial" "css_element"
+    And I click on "M" "link" in the ".lastinitial" "css_element"
+    Then I should see "Vinnie Money" in the "grading-report" "table"
+    And I should not see "Anna Moe" in the "grading-report" "table"
+    And I should not see "Anna Velvet" in the "grading-report" "table"
+
+  Scenario: Filter submissions report and see nothing.
+    Given I am on the "Music history" "workshop activity" page logged in as teacher1
+    And I change phase in workshop "Music history" to "Submission phase"
