### Question:
SequencingService implements AdministeredService { public Selector getSequencerSelector() { return this.sequencerSelector; } SequencingService(); ServiceAdministrator getAdministrator(); Statistics getStatistics(); boolean addSequencer( SequencerConfig config ); List<SequencerConfig> getSequencers(); boolean updateSequencer( SequencerConfig config ); boolean removeSequencer( SequencerConfig config ); ExecutionContext getExecutionContext(); void setExecutionContext( ExecutionContext executionContext ); RepositoryLibrary getRepositoryLibrary(); void setRepositoryLibrary( RepositoryLibrary repositoryLibrary ); ExecutorService getExecutorService(); void setExecutorService( ExecutorService executorService ); Selector getSequencerSelector(); void setSequencerSelector( Selector sequencerSelector ); void setSequencersList( List<Sequencer> sequencersList ); List<Sequencer> getSequencersList(); static final Selector DEFAULT_SEQUENCER_SELECTOR; }### Answer:
@Test public void shouldHaveTheDefaultSelectorUponConstruction() { assertThat(sequencingService.getSequencerSelector(), is(sameInstance(SequencingService.DEFAULT_SEQUENCER_SELECTOR))); }
