-Feature: Creating the source
-
-  Scenario Outline: Adding an new unique source
-    Given the label "<label>"
-    And the path "<source_path>"
-    And the destinations <destinations>
-    And the arguments "<arguments>"
-    When I add the source
-    Then the source should be added successfully
-
-    Examples:
-      | label | source_path | destinations                     | arguments      |
-      | usb   | /mnt/usb    | []                               | <empty>        |
-      | db    | /db         | ["/backup/db"]                   | -avuP          |
-      | temp  | /tmp        | ["/backup/tmp1", "/backup/tmp2"] | -avuP --delete |
