### Question:
JobEntryAnalyzerProvider extends BaseKettleMetaverseComponent implements IJobEntryAnalyzerProvider { public void setJobEntryAnalyzers( List<IJobEntryAnalyzer> analyzers ) { if ( analyzers == null ) { this.jobEntryAnalyzers = null; } else { if ( this.jobEntryAnalyzers == null ) { this.jobEntryAnalyzers = new ArrayList(); } for ( final IJobEntryAnalyzer analyzer : analyzers ) { if ( !jobEntryAnalyzers.contains( analyzer ) ) { jobEntryAnalyzers.add( analyzer ); } } loadAnalyzerTypeMap(); } }  @Override List<IJobEntryAnalyzer> getAnalyzers(); @Override List<IJobEntryAnalyzer> getAnalyzers( Collection<Class<?>> types ); void setJobEntryAnalyzers( List<IJobEntryAnalyzer> analyzers ); void setClonableJobEntryAnalyzers( List<IJobEntryAnalyzer> analyzers ); @Override void addAnalyzer( IJobEntryAnalyzer analyzer ); void addClonableAnalyzer( IClonableJobEntryAnalyzer analyzer ); @Override void removeAnalyzer( IJobEntryAnalyzer analyzer ); void removeClonableAnalyzer( IClonableJobEntryAnalyzer analyzer );  }### Answer:
@Test public void testsetJobEntryAnalyzersNull() throws Exception { assertNotNull( provider.jobEntryAnalyzers ); assertTrue( provider.jobEntryAnalyzers.isEmpty() ); provider.setJobEntryAnalyzers( null ); assertNull( provider.jobEntryAnalyzers ); }
@Test public void testsetJobEntryAnalyzers() throws Exception { assertNotNull( provider.jobEntryAnalyzers ); assertTrue( provider.jobEntryAnalyzers.isEmpty() ); List<IJobEntryAnalyzer> analyzerSet = new ArrayList<IJobEntryAnalyzer>() {{ add( mockJobEntryAnalyzer ); }}; provider.setJobEntryAnalyzers( analyzerSet ); assertFalse( provider.jobEntryAnalyzers.isEmpty() ); }
