+    And I am visiting the "Demo translatable page" create node page
+    Then I should not see selectbox with label "Language"
+
+    When I fill in "Title" with "Title Default value"
+    And I fill in "Body" with "Body Default value"
+    And I press "Save"
+    Then I should see the success message "Demo translatable page Title Default value has been created."
+
+    When I click "Translate"
+    Then I have to be sure that "Title Default value" node translation only in site default language.
