Review comment:
       1.This is a good test scenario, but windows system does not have the 
permission information of group/other  IIRC.
   2.If it is a Windows operating platform, it will skip the permission logic, 
because the Windows system itself does not have detailed executable permission, 
only read and write permission,the method of canExecute defaults to true on 
Windows systems.
