### Question:
TableInputStepAnalyzer extends ConnectionExternalResourceStepAnalyzer<TableInputMeta> { @Override protected Set<StepField> getUsedFields( TableInputMeta meta ) { return null; }  @Override Set<Class<? extends BaseStepMeta>> getSupportedSteps(); @Override String getResourceInputNodeType(); @Override String getResourceOutputNodeType(); @Override boolean isOutput(); @Override boolean isInput(); @Override IMetaverseNode getConnectionNode(); void setBaseStepMeta( TableInputMeta meta ); @Override String toString();  }### Answer:
@Test public void testGetUsedFields() throws Exception { assertNull( analyzer.getUsedFields( meta ) ); }
