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