### Question:
FilterRowsStepAnalyzer extends StepAnalyzer<FilterRowsMeta> { @Override public Set<Class<? extends BaseStepMeta>> getSupportedSteps() { Set<Class<? extends BaseStepMeta>> supportedSteps = new HashSet<>(); supportedSteps.add( FilterRowsMeta.class ); return supportedSteps; }  @Override Set<Class<? extends BaseStepMeta>> getSupportedSteps(); @Override IClonableStepAnalyzer newInstance(); static final String DATA_FLOW_CONDITION; }### Answer:
@Test public void testGetSupportedSteps() throws Exception { Set<Class<? extends BaseStepMeta>> supportedSteps = analyzer.getSupportedSteps(); assertNotNull( supportedSteps ); assertTrue( supportedSteps.contains( FilterRowsMeta.class ) ); }
