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