      vdirsyncer.tests.storage.test_caldav
      ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  
      Using an actual CalDAV server to test the CalDAV storage. Done by using
      Werkzeug's test client for WSGI apps. While this is pretty fast, Radicale
      has so much global state such that a clean separation of the unit tests is
      not guaranteed.
