   I'm not sure how to go about setting up a test case for this. I have been using this makeshift test which happens to work on my laptop where files within /tmp are restricted:
   
   ```c++
   // localfs_test.cc
   TYPED_TEST(TestLocalFS, TraverseSomeRestrictedContent) {
     auto fs = std::make_shared<LocalFileSystem>();
     FileSelector file_selector;
     file_selector.base_dir = "/tmp";
     file_selector.allow_not_found = true;
     file_selector.allow_errors = true;
     file_selector.recursive = true;
     std::vector<FileInfo> infos;
     ASSERT_OK_AND_ASSIGN(infos, fs->GetFileInfo(file_selector));
   }
   ```
