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