### Question:
AAICreateTasks { public List<String> splitCDL(String str) { return Stream.of(str.split(",")).map(String::trim).map(elem -> new String(elem)).collect(Collectors.toList()); }  void createServiceInstance(BuildingBlockExecution execution); void createServiceSubscription(BuildingBlockExecution execution); void createProject(BuildingBlockExecution execution); void createOwningEntity(BuildingBlockExecution execution); void createVnf(BuildingBlockExecution execution); void createPnf(BuildingBlockExecution execution); void createPlatformForNetwork(BuildingBlockExecution execution); void createPlatform(BuildingBlockExecution execution); List<String> splitCDL(String str); void createLineOfBusiness(BuildingBlockExecution execution); void createLineOfBusinessForNetwork(BuildingBlockExecution execution); void createVolumeGroup(BuildingBlockExecution execution); void createVfModule(BuildingBlockExecution execution); void connectVfModuleToVolumeGroup(BuildingBlockExecution execution); void createNetwork(BuildingBlockExecution execution); void createCustomer(BuildingBlockExecution execution); void createNetworkCollection(BuildingBlockExecution execution); void createNetworkCollectionInstanceGroup(BuildingBlockExecution execution); void connectNetworkToTenant(BuildingBlockExecution execution); void connectNetworkToCloudRegion(BuildingBlockExecution execution); void connectVnfToCloudRegion(BuildingBlockExecution execution); void connectVnfToTenant(BuildingBlockExecution execution); void connectNetworkToNetworkCollectionServiceInstance(BuildingBlockExecution execution); void connectNetworkToNetworkCollectionInstanceGroup(BuildingBlockExecution execution); void createConfiguration(BuildingBlockExecution execution); void createInstanceGroupVnf(BuildingBlockExecution execution); void createNetworkPolicies(BuildingBlockExecution execution);  }### Answer:
@Test public void splitCDL_Test() throws Exception { List<String> strings = aaiCreateTasks.splitCDL("Test"); assertEquals(strings.get(0), "Test"); List<String> strings2 = aaiCreateTasks.splitCDL(""); assertEquals(strings2.get(0), ""); }
