### Question:
TalendOutputEntity extends TalendEntity { @Override public void connectToEntity(List<String> inputs, List<String> outputs) { for (String input : inputs) { String id = GeneratorID.generateNodeID(this.getJobId(), input); this.addPreviousEntity(id); } this.addNextEntity(this.getEntityId()); } TalendOutputEntity(String jobId, String componentName); void addPreviousEntity(String entityId); void addNextEntity(String entityId); List<String> getPreviousEntitiesId(); List<String> getNextEntitiesId(); List<EndPointProxy> getSourceProxies(); List<EndPointProxy> getTargetProxies(); @Override String toString(); @Override void connectToEntity(List<String> inputs, List<String> outputs);  }### Answer:
@Test public void testConnectToEntity() { TalendOutputEntity toe = new TalendOutputEntity("job", "component1"); assertEquals(0, toe.getPreviousEntitiesId().size()); assertEquals(0, toe.getNextEntitiesId().size()); toe.connectToEntity(Arrays.asList("component2", "component3"), Arrays.asList("component4", "component5")); assertEquals(1, toe.getNextEntitiesId().size()); assertEquals(2, toe.getPreviousEntitiesId().size()); assertEquals(2, toe.getSourceProxies().size()); assertEquals(1, toe.getTargetProxies().size()); assertEquals( "[" + GeneratorID.generateNodeID("job", "component2") + ", " + GeneratorID.generateNodeID("job", "component3") + "]---> component1 (" + GeneratorID.generateEntityID("job", "component1") + ")", toe.toString()); }
