### Question:
TextFileInputStepAnalyzer extends ExternalResourceStepAnalyzer<TextFileInputMeta> { @Override public Set<Class<? extends BaseStepMeta>> getSupportedSteps() { return new HashSet<Class<? extends BaseStepMeta>>() { { add( TextFileInputMeta.class ); } }; }  @Override Set<Class<? extends BaseStepMeta>> getSupportedSteps(); @Override IMetaverseNode createResourceNode( IExternalResourceInfo resource ); @Override String getResourceInputNodeType(); @Override String getResourceOutputNodeType(); @Override boolean isOutput(); @Override boolean isInput();  }### Answer:
@Test public void testGetSupportedSteps() { TextFileInputStepAnalyzer analyzer = new TextFileInputStepAnalyzer(); Set<Class<? extends BaseStepMeta>> types = analyzer.getSupportedSteps(); assertNotNull( types ); assertEquals( types.size(), 1 ); assertTrue( types.contains( TextFileInputMeta.class ) ); }
