§58-28.
   
   At the time appointed for the hearing, or at the time to which the
   hearing may have been postponed, the court, unless the parties appear,
   must require proof that the notice has been given, which being made,
   the court must hear testimony in proof of the will. If such notice is
   not proved to have been given, or if from any other cause it is
   necessary, the hearing may be postponed to a day certain. The
   appearance in court of parties interested is a waiver of notice.
