### Question:
TransformationAnalyzer extends BaseDocumentAnalyzer { protected BaseStepMeta getBaseStepMetaFromStepMeta( StepMeta stepMeta ) { BaseStepMeta baseStepMeta = new BaseStepMeta(); baseStepMeta.setParentStepMeta( stepMeta ); if ( stepMeta != null ) { StepMetaInterface smi = stepMeta.getStepMetaInterface(); if ( smi instanceof BaseStepMeta ) { baseStepMeta = (BaseStepMeta) smi; } } return baseStepMeta; }  @Override synchronized IMetaverseNode analyze( IComponentDescriptor descriptor, IDocument document ); @Override synchronized IMetaverseNode analyze(
    final IComponentDescriptor documentDescriptor, final AbstractMeta meta, final IMetaverseNode node,
    final String documentPath ); Set<String> getSupportedTypes(); void setStepAnalyzerProvider( IStepAnalyzerProvider stepAnalyzerProvider ); IStepAnalyzerProvider getStepAnalyzerProvider(); @Override IClonableDocumentAnalyzer newInstance();  }### Answer:
@Test public void testGetBaseStepMetaFromStepMetaWithNull() { BaseStepMeta baseStepMeta = analyzer.getBaseStepMetaFromStepMeta( null ); assertNotNull( baseStepMeta ); assertNull( baseStepMeta.getParentStepMeta() ); }
