### Question:
ConfiguratorBase { public static void setVisibilityCacheSize(Configuration conf, int visibilityCacheSize) { conf.setInt(enumToConfKey(GeneralOpts.VISIBILITY_CACHE_SIZE), visibilityCacheSize); }  static void setClientProperties(Class<?> implementingClass, Configuration conf,
      Properties props, String clientPropsPath); static Properties getClientProperties(Class<?> implementingClass, Configuration conf); static Boolean isClientConfigured(Class<?> implementingClass, Configuration conf); static AccumuloClient createClient(Class<?> implementingClass, Configuration conf); static void setVisibilityCacheSize(Configuration conf, int visibilityCacheSize); static int getVisibilityCacheSize(Configuration conf); static void setJobStored(Class<?> implementingClass, Configuration conf); static void checkJobStored(Class<?> implementingClass, Configuration conf);  }### Answer:
@Test public void testSetVisibilityCacheSize() { Configuration conf = new Configuration(); assertEquals(Constants.DEFAULT_VISIBILITY_CACHE_SIZE, ConfiguratorBase.getVisibilityCacheSize(conf)); ConfiguratorBase.setVisibilityCacheSize(conf, 2000); assertEquals(2000, ConfiguratorBase.getVisibilityCacheSize(conf)); }
