### Question:
DummyStepAnalyzer extends StepAnalyzer<DummyTransMeta> { @Override public Set<Class<? extends BaseStepMeta>> getSupportedSteps() { Set<Class<? extends BaseStepMeta>> supportedSteps = new HashSet<>(); supportedSteps.add( DummyTransMeta.class ); return supportedSteps; }  @Override Set<Class<? extends BaseStepMeta>> getSupportedSteps();  }### Answer:
@Test public void testGetSupportedSteps() throws Exception { Set<Class<? extends BaseStepMeta>> supportedSteps = analyzer.getSupportedSteps(); assertNotNull( supportedSteps ); assertEquals( 1, supportedSteps.size() ); assertEquals( DummyTransMeta.class, supportedSteps.iterator().next() ); }
