### Question:
JobEntryAnalyzer extends BaseKettleMetaverseComponent implements
  IClonableJobEntryAnalyzer<IMetaverseNode, T> { @Override public IMetaverseNode analyze( IComponentDescriptor descriptor, T entry ) throws MetaverseAnalyzerException { validateState( descriptor, entry ); this.descriptor = descriptor; rootNode = createNodeFromDescriptor( descriptor ); String stepType = null; try { stepType = PluginRegistry.getInstance().findPluginWithId( JobEntryPluginType.class, entry.getPluginId() ).getName(); } catch ( Throwable t ) { stepType = entry.getClass().getSimpleName(); } rootNode.setProperty( DictionaryConst.PROPERTY_PLUGIN_ID, entry.getPluginId() ); rootNode.setProperty( DictionaryConst.PROPERTY_JOB_ENTRY_TYPE, stepType ); rootNode.setProperty( DictionaryConst.PROPERTY_COPIES, entry.getParentJob().getJobMeta().getJobCopies().size() ); rootNode.setProperty( DictionaryConst.PROPERTY_DESCRIPTION, entry.getDescription() ); rootNode.setProperty( DictionaryConst.PROPERTY_ANALYZER, this.getClass().getSimpleName() ); metaverseBuilder.addNode( rootNode ); customAnalyze( entry, rootNode ); return rootNode; }  @Override IMetaverseNode analyze( IComponentDescriptor descriptor, T entry ); IConnectionAnalyzer<Object, T> getConnectionAnalyzer(); void setConnectionAnalyzer( IConnectionAnalyzer<Object, T> connectionAnalyzer ); IComponentDescriptor getDescriptor(); void setDescriptor( IComponentDescriptor descriptor ); @Override final IClonableJobEntryAnalyzer cloneAnalyzer(); @Override void setDocumentAnalyzer( final IClonableDocumentAnalyzer documentAnalyzer ); @Override IClonableDocumentAnalyzer getDocumentAnalyzer(); @Override void setDocumentDescriptor( final IComponentDescriptor documentDescriptor ); @Override void setDocumentPath( final String documentPath ); @Override IComponentDescriptor getDocumentDescriptor();  }### Answer:
@Test( expected = MetaverseAnalyzerException.class ) public void testNullAnalyze() throws MetaverseAnalyzerException { analyzer.analyze( mockDescriptor, null ); }
@Test public void testAnalyzeWithDatabaseMeta() throws MetaverseAnalyzerException { DatabaseMeta[] dbs = new DatabaseMeta[] { mockDatabaseMeta }; when( mockJobEntryInterface.getUsedDatabaseConnections() ).thenReturn( dbs ); assertNotNull( analyzer.analyze( mockDescriptor, mockJobEntryInterface ) ); }
@Test( expected = MetaverseAnalyzerException.class ) public void testSetMetaverseBuilderNull() throws MetaverseAnalyzerException { analyzer.setMetaverseBuilder( null ); analyzer.analyze( mockDescriptor, mockJobEntryInterface ); }
