/// @assertion void deleteSync({bool recursive: false})
/// Synchronously deletes this FileSystemEntity.
///
/// If the FileSystemEntity is a directory, and if recursive is false, the
/// directory must be empty. Otherwise, if recursive is true, the directory and
/// all sub-directories and files in the directories are deleted. Links are not
/// followed when deleting recursively. Only the link is deleted, not its
/// target.
///
/// If recursive is true, the FileSystemEntity is deleted even if the type of
/// the FileSystemEntity doesn't match the content of the file system. This
/// behavior allows deleteSync to be used to unconditionally delete any file
/// system object.
///
/// Throws an exception if the FileSystemEntity cannot be deleted.
/// @description Checks that a FileSystemEntity is thrown if the
/// FileSystemEntity cannot be deleted
///
/// @note The test should run with the Administrator priveleges on Windows.
/// Dart API Spec reads:
/// In order to create a symbolic link on Windows, Dart must be run in
/// Administrator mode or the system must have Developer Mode enabled, otherwise
/// a FileSystemException will be raised with ERROR_PRIVILEGE_NOT_HELD set as
/// the errno when this call is made.
