### Question:
NodeTermScorer extends NodePositionScorer { @Override public boolean nextPosition() throws IOException { return docsEnum.nextPosition(); } protected  NodeTermScorer(final Weight weight,
                           final DocsNodesAndPositionsEnum docsEnum,
                           final Similarity.ExactSimScorer docScorer); @Override int doc(); @Override float freqInNode(); @Override int pos(); @Override IntsRef node(); @Override boolean nextCandidateDocument(); @Override boolean nextNode(); @Override boolean nextPosition(); @Override float scoreInNode(); @Override boolean skipToCandidate(final int target); @Override String toString();  }### Answer:
@Test public void testNextPositionFail() throws Exception { this.addDocument("<http: final NodeTermScorer scorer = (NodeTermScorer) this.getScorer(ntq("renaud")); assertFalse(scorer.nextPosition()); }
