### Question:
NaluPluginCoreWeb { public static boolean isSuperDevMode() { return "on".equals(System.getProperty("superdevmode", "off")); }  static boolean isSuperDevMode(); @SuppressWarnings("StringSplitter") static void getContextPath(ShellConfiguration shellConfiguration); @SuppressWarnings("StringSplitter") static NaluStartModel getNaluStartModel(); static void addPopStateHandler(RouteChangeHandler handler,
                                        String contextPath); static void route(String newRoute,
                           boolean replace,
                           RouteChangeHandler handler); static void addOnHashChangeHandler(RouteChangeHandler handler);  }### Answer:
@Test void isSuperDevMode() { System.setProperty("superdevmode", "on"); Assertions.assertTrue(NaluPluginCoreWeb.isSuperDevMode()); }
@Test void isNotSuperDevMode() { System.setProperty("superdevmode", "off"); Assertions.assertFalse(NaluPluginCoreWeb.isSuperDevMode()); }
