### Question:
StepAnalyzer extends BaseKettleMetaverseComponent implements
  IClonableStepAnalyzer<T>, IFieldLineageMetadataProvider<T> { protected Map<String, RowMetaInterface> getOutputRowMetaInterfaces( T meta ) { return getOutputRowMetaInterfaces( parentTransMeta, parentStepMeta, meta, true ); }  @Override IMetaverseNode analyze( IComponentDescriptor descriptor, T meta ); @Override void postAnalyze( T meta ); Set<String> getInputStepNames( final T meta, final String fieldName ); String getStepName(); StepNodes getInputs(); StepNodes getOutputs(); void setDescriptor( IComponentDescriptor descriptor ); IComponentDescriptor getDescriptor(); Set<StepField> createStepFields( String fieldName, StepNodes stepNodes ); void validateState( IComponentDescriptor descriptor, T object ); IConnectionAnalyzer getConnectionAnalyzer(); void setConnectionAnalyzer( IConnectionAnalyzer connectionAnalyzer ); Map<String, RowMetaInterface> getInputFields( final TransMeta parentTransMeta,
                                                       final StepMeta parentStepMeta ); @Override Map<String, RowMetaInterface> getInputFields( T meta ); @Override RowMetaInterface getOutputFields( T meta ); @Override Set<IFieldMapping> getFieldMappings( T meta ); @Override Set<ComponentDerivationRecord> getChangeRecords( T meta ); void loadInputAndOutputStreamFields( T meta ); @Override final IClonableStepAnalyzer cloneAnalyzer(); IMetaverseNode getNode( final String name, final String type, final INamespace namespace,
                                 final String nodeKey, final Map<String, IMetaverseNode> nodeMap ); @Override void setDocumentAnalyzer( final IClonableDocumentAnalyzer documentAnalyzer ); @Override IClonableDocumentAnalyzer getDocumentAnalyzer(); @Override void setDocumentDescriptor( final IComponentDescriptor documentDescriptor ); @Override IComponentDescriptor getDocumentDescriptor(); @Override void setDocumentPath( final String documentPath ); static final String NONE; }### Answer:
@Test public void testGetOutputRowMetaInterfaces() throws Exception { String[] nextStepNames = new String[]{ "nextStep1" }; when( parentTransMeta.getNextStepNames( parentStepMeta ) ).thenReturn( nextStepNames ); RowMetaInterface rowMetaInterface = mock( RowMetaInterface.class ); doReturn( rowMetaInterface ).when( analyzer ).getOutputFields( baseStepMeta ); Map<String, RowMetaInterface> rowMetaInterfaces = analyzer.getOutputRowMetaInterfaces( baseStepMeta ); assertNotNull( rowMetaInterfaces ); assertEquals( nextStepNames.length, rowMetaInterfaces.size() ); assertEquals( rowMetaInterface, rowMetaInterfaces.get( nextStepNames[0] ) ); }
