### Question:
TransExecutorStepAnalyzer extends StepAnalyzer<TransExecutorMeta> { @Override protected boolean isPassthrough( StepField originalFieldName ) { return false; } TransExecutorStepAnalyzer(); void connectToSubTransOutputFields( TransExecutorMeta meta, TransMeta subTransMeta,
                                             IMetaverseNode subTransNode,
                                             IComponentDescriptor descriptor ); void connectToSubTransInputFields( TransMeta subTransMeta,
                                            IMetaverseNode subTransNode,
                                            IComponentDescriptor descriptor ); @Override Set<Class<? extends BaseStepMeta>> getSupportedSteps(); @Override IClonableStepAnalyzer newInstance(); static final String EXECUTION_RESULTS_TARGET; static final String OUTPUT_ROWS_TARGET; static final String RESULT_FILES_TARGET; }### Answer:
@Test public void testIsPassthrough() { StepField stepField = new StepField( "previousStep", "one" ); assertFalse( spyAnalyzer.isPassthrough( stepField ) ); }
