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