### Question:
MulgaraConnector extends TriplestoreConnector { @Override public TriplestoreReader getReader() { if (m_reader == null){ try{ open(); } catch(TrippiException e){ logger.error(e.toString(),e); } } return m_reader; }  @Override void close(); @Override GraphElementFactory getElementFactory(); @Override TriplestoreReader getReader(); @Override TriplestoreWriter getWriter(); @Deprecated @Override void init(Map<String, String> config); @Override void setConfiguration(Map<String, String> config); @Override void setTripleIteratorFactory(TripleIteratorFactory factory); @Override Map<String,String> getConfiguration(); @Override void open();  }### Answer:
@Test public void testGetReader() throws Exception { TriplestoreReader reader = _connector.getReader(); assertEquals(0, reader.countTriples(null, null, null, -1)); }
