### Question:
BootStrap implements Runnable { static public Path toRootRealPath() { Path realPathName; try { if (NetShellConfiguration.getInstance() != null) { BootStrap.masterConfiguration = NetShellConfiguration.getInstance().getGlobal(); if (masterConfiguration == null) { realPathName = Paths.get("/"); } else if (masterConfiguration.getRootDirectory() != null) { realPathName = Paths.get( new File(masterConfiguration.getRootDirectory()).getCanonicalFile().toString()); } else { realPathName = Paths.get(new File(DefaultValues.NETSHELL_DEFAULT_ROOTDIR).getCanonicalFile().toString()); } } else { realPathName = Paths.get("/"); } } catch (IOException e) { throw new RuntimeException(e.getMessage()); } return realPathName; } BootStrap(); static Path toRootRealPath(); Shell getShell(); SShd getSshd(); String[] getArgs(); KernelSecurityManager getSecurityManager(); BundleContext getBundleContext(); DataBase getDataBase(); void setDataBase(DataBase dbClient); static void setSingleton(BootStrap bootStrap); PythonShellService getPythonService(); void setPythonService(PythonShellService pythonService); boolean isStandAlone(); void init(); static void main(String[] args); static void main(String[] args, BundleContext bundleContext); static BootStrap getBootStrap(); static BootStrap getBootStrap(String[] args, BundleContext bundleContext); void startServices(); void stop(); @Override void run(); boolean shutdown(); @SysCall(name = "do_shutdown") void do_shutdown(); static Path rootPath; }### Answer:
@Test public void testToRootRealPath() throws Exception { }
