### Question:
OpenNlpPosTagger extends AbstractPosTagger { public OpenNlpPosTagger(File modelFile) { Validate.notNull(modelFile, "The model file must not be null."); this.tagger = loadModel(modelFile); } OpenNlpPosTagger(File modelFile); @Override String getName();  }### Answer:
@Test public void testOpenNlpPosTagger() { OpenNlpPosTagger posTagger = new OpenNlpPosTagger(modelFile); List<Annotation> annotations = posTagger.getAnnotations(TEXT); assertEquals(10, annotations.size()); assertEquals("DT", annotations.get(0).getTag()); assertEquals("JJ", annotations.get(1).getTag()); assertEquals("JJ", annotations.get(2).getTag()); assertEquals("NN", annotations.get(3).getTag()); assertEquals("NNS", annotations.get(4).getTag()); assertEquals("IN", annotations.get(5).getTag()); assertEquals("DT", annotations.get(6).getTag()); assertEquals("JJ", annotations.get(7).getTag()); assertEquals("NN", annotations.get(8).getTag()); assertEquals(".", annotations.get(9).getTag()); }
