### Question:
RowsToResultStepAnalyzer extends StepAnalyzer<RowsToResultMeta> { @Override public Set<Class<? extends BaseStepMeta>> getSupportedSteps() { Set<Class<? extends BaseStepMeta>> supportedSteps = new HashSet<Class<? extends BaseStepMeta>>( 1 ); supportedSteps.add( RowsToResultMeta.class ); return supportedSteps; }  @Override Set<Class<? extends BaseStepMeta>> getSupportedSteps(); @Override IClonableStepAnalyzer newInstance();  }### Answer:
@Test public void testGetSupportedSteps() { RowsToResultStepAnalyzer analyzer = new RowsToResultStepAnalyzer(); Set<Class<? extends BaseStepMeta>> types = analyzer.getSupportedSteps(); assertNotNull( types ); assertEquals( types.size(), 1 ); assertTrue( types.contains( RowsToResultMeta.class ) ); }
