+  Scenario Outline: send sharing invitation to already shared group
+    Given user "Carol" has been created with default attributes and without skeleton files
+    And group "grp1" has been created
+    And the following users have been added to the following groups
+      | username | groupname |
+      | Brian    | grp1      |
+      | Carol    | grp1      |
+    And user "Alice" has uploaded file with content "to share" to "/textfile1.txt"
+    And user "Alice" has created folder "FolderToShare"
+    And user "Alice" has sent the following share invitation:
+      | resourceType    | <resource-type>    |
+      | resource        | <path>             |

+      | shareType       | group              |
+      | permissionsRole | <permissions-role> |
+    When user "Alice" sends the following share invitation using the Graph API:
+      | resourceType    | <resource-type>    |
+      | resource        | <path>             |

+      | shareType       | group              |
+      | permissionsRole | <permissions-role> |
