### Question:
CaliperConfig { public ImmutableSet<Class<? extends ResultProcessor>> getConfiguredResultProcessors() { return resultProcessorConfigs.keySet(); } @VisibleForTesting  CaliperConfig(ImmutableMap<String, String> properties); ImmutableMap<String, String> properties(); VmConfig getDefaultVmConfig(); VmConfig getVmConfig(String name); ImmutableSet<String> getConfiguredInstruments(); InstrumentConfig getInstrumentConfig(String name); ImmutableSet<Class<? extends ResultProcessor>> getConfiguredResultProcessors(); ResultProcessorConfig getResultProcessorConfig(
      Class<? extends ResultProcessor> resultProcessorClass); @Override String toString();  }### Answer:
@Test public void getConfiguredResultProcessors() throws Exception { assertEquals(ImmutableSet.of(), new CaliperConfig(ImmutableMap.<String, String>of()).getConfiguredResultProcessors()); CaliperConfig configuration = new CaliperConfig(ImmutableMap.of( "results.test.class", TestResultProcessor.class.getName())); assertEquals(ImmutableSet.of(TestResultProcessor.class), configuration.getConfiguredResultProcessors()); }
