Our project is not currently using a spring framework.
Therefore, it is being tested based on the standalone tomcat runner.
However, since integration-enabled tests such as #SpringBootTest are not possible, Tomcat is operated in advance and the HTTP API test is carried out using Spock.
Is there a way to turn this like #SpringBootTest?
TomcatRunner
private Tomcat tomcat = null;
private int port = 8080;
private String contextPath = null;
private String docBase = null;
private Context rootContext = null;
public Tomcat8Launcher(){
init();
}
public Tomcat8Launcher(int port, String contextPath, String docBase){
this.port = port;
this.contextPath = contextPath;
this.docBase = docBase;
init();
}
private void init(){
tomcat = new Tomcat();
tomcat.setPort(port);
tomcat.enableNaming();
if(contextPath == null){
contextPath = "";
}
if(docBase == null){
File base = new File(System.getProperty("java.io.tmpdir"));
docBase = base.getAbsolutePath();
}
rootContext = tomcat.addContext(contextPath, docBase);
}
public void addServlet(String servletName, String uri, HttpServlet servlet){
Tomcat.addServlet(this.rootContext, servletName, servlet);
rootContext.addServletMapping(uri, servletName);
}
public void addListenerServlet(ServletContextListener listener){
rootContext.addApplicationListener(listener.getClass().getName());
}
public void startServer() throws LifecycleException {
tomcat.start();
tomcat.getServer().await();
}
public void stopServer() throws LifecycleException {
tomcat.stop();
}
public static void main(String[] args) throws Exception {
System.setProperty("java.util.logging.manager", "org.apache.logging.log4j.jul.LogManager");
System.setProperty(javax.naming.Context.INITIAL_CONTEXT_FACTORY, "org.apache.naming.java.javaURLContextFactory");
System.setProperty(javax.naming.Context.URL_PKG_PREFIXES, "org.apache.naming");
Tomcat8Launcher tomcatServer = new Tomcat8Launcher();
tomcatServer.addListenerServlet(new ConfigInitBaseServlet());
tomcatServer.addServlet("restServlet", "/rest/*", new RestServlet());
tomcatServer.addServlet("jsonServlet", "/json/*", new JsonServlet());
tomcatServer.startServer();
}
Spock API Test example
class apiTest extends Specification {
//static final Tomcat8Launcher tomcat = new Tomcat8Launcher()
static final String testURL = "http://localhost:8080/api/"
#Shared
def restClient
def setupSpec() {
// tomcat.main()
restClient = new RESTClient(testURL)
}
def 'findAll user'() {
when:
def response = restClient.get([path: 'user/all'])
then:
with(response){
status == 200
contentType == "application/json"
}
}
}
The test will not work if the annotations are removed from the annotations below.
// static final Tomcat8Launcher tomcat = new Tomcat8Launcher()
This line is specified API Test at the top.
// tomcat.main()
This line is specified API Test setupSpec() method
I don't know why, but only logs are recorded after Tomcat has operated and the test method is not executed.
Is there a way to fix this?
I would suggest to create a Spock extension to encapsulate everything you need. See writing custom extensions of the Spock docs as well as the built-in extensions for inspiration.

I need to test some REST client. For that purpose I'm using org.mockserver.integration.ClientAndServer
I start my server. Create some expectation. After that I mock my client. Run this client. But when server receives request I see in logs:
14:00:13.511 [MockServer-EventLog0] INFO org.mockserver.log.MockServerEventLog - received binary request:
505249202a20485454502f322e300d0a0d0a534d0d0a0d0a00000604000000000000040100000000000408000000000000ff0001

This is my test:
#RunWith(PowerMockRunner.class)
#PrepareForTest({NrfClient.class, SnefProperties.class})
#PowerMockIgnore({"javax.net.ssl.*"})
#TestPropertySource(locations = "classpath:test.properties")
public class NrfConnectionTest {
private String finalPath;
private UUID uuid = UUID.fromString("8d92d4ac-be0e-4016-8b2c-eff2607798e4");
private ClientAndServer mockServer;
#Before
public void startMockServer() {
mockServer = startClientAndServer(8888);
}
#After
public void stopServer() {
mockServer.stop();
}
#Test
public void NrfRegisterTest() throws Exception {
//create some expectation
new MockServerClient("127.0.0.1", 8888)
.when(HttpRequest.request()
.withMethod("PUT")
.withPath("/nnrf-nfm/v1/nf-instances/8d92d4ac-be0e-4016-8b2c-eff2607798e4"))
.respond(HttpResponse.response().withStatusCode(201));
//long preparations and mocking the NrfClient (client that actually make request)
//NrfClient is singleton, so had to mock a lot of methods.
PropertiesConfiguration config = new PropertiesConfiguration();
config.setAutoSave(false);
File file = new File("test.properties");
if (!file.exists()) {
String absolutePath = file.getAbsolutePath();
finalPath = absolutePath.substring(0, absolutePath.length() - "test.properties".length()) + "src\\test\\resources\\test.properties";
file = new File(finalPath);
}
try {
config.load(file);
config.setFile(file);
} catch(ConfigurationException e) {
LogUtils.warn(NrfConnectionTest.class, "Failed to load properties from file " + "classpath:test.properties", e);
}
SnefProperties spyProperties = PowerMockito.spy(SnefProperties.getInstance());
PowerMockito.doReturn(finalPath).when(spyProperties, "getPropertiesFilePath");
PowerMockito.doReturn(config).when(spyProperties, "getProperties");
PowerMockito.doReturn(config).when(spyProperties, "getLastUpdatedProperties");
NrfConfig nrfConfig = getNrfConfig();
NrfClient nrfClient = PowerMockito.spy(NrfClient.getInstance());
SnefAddressInfo snefAddressInfo = new SnefAddressInfo("127.0.0.1", "8080");
PowerMockito.doReturn(nrfConfig).when(nrfClient, "loadConfiguration", snefAddressInfo);
PowerMockito.doReturn(uuid).when(nrfClient, "getUuid");
Whitebox.setInternalState(SnefProperties.class, "instance", spyProperties);
nrfClient.initialize(snefAddressInfo);
//here the client makes request
nrfClient.run();
}
private NrfConfig getNrfConfig() {
NrfConfig nrfConfig = new NrfConfig();
nrfConfig.setNrfDirectConnection(true);
nrfConfig.setNrfAddress("127.0.0.1:8888");
nrfConfig.setSnefNrfService(State.ENABLED);
nrfConfig.setSmpIp("127.0.0.1");
nrfConfig.setSmpPort("8080");
return nrfConfig;
}
}
Looks like I miss some server configuration, or use it in wrong way.
Or, maybe the reason is in powermock: could it be that mockserver is incompatible with powermock or PowerMockRunner?
I am having issue when I deploy the jar in AWS ubuntu server,I have 2 packages in Spring Boot.
#1)core package
#2)Process package
The first package(core) is not containing spring boot dependency and generate the jar using maven package,When I run the code the below code works fine in Intellij. But when I deploy in AWS Ubuntu machine I get Null Pointer Exception for MySQLAdapter Class used in the Process PackageController.
Below is the code
//Code in Process
#SpringBootApplication
public class ProcessApplication
{
#Bean
MySQLAdapter mySQLAdapter() {
MySQLAdapter mySQLAdapter = new MySQLAdapter();
return mySQLAdapter;
}
public static void main(String[] args) {
SpringApplication.run(com.test.ProcessApplication.class, args);
}
}
// Core package jar
public class MySQLAdapter {
private String hostName;
private int port;
private String DBName;
private String username;
private String pwd;
private String secretPwdKey;
private com.test.Util.CryptoUtil cryptoUtil;
public MySQLAdapter() {
hostName = "localhost";
port = 3306;
username = "test";
pwd = "test";
DBName = "test";
secretPwdKey = "test";
cryptoUtil = new com.test.Util.CryptoUtil();
}
}
Is this Null Pointer Exception because of cryptoUtil not getting injected or instantiated?
How can this be solved?
// Controller inside Process package
#RestController
class MyRestController{
#Autowired
MySQLAdapter mySQLAdapter;
#RequestMapping(value = {"/register"}, method = {RequestMethod.POST}, produces = {"application/json"})
#ResponseBody
public RegistrationResponse register(#Valid #RequestBody UserPojo userPojo) {
if (!this.mySQLAdapter.checkClientID(userPojo.getClientID())) { //Null Pointer thrown here
}
}
}
I would like to write some integration with ElasticSearch. For testing I would like to run in-memory ES.
I found some information in documentation, but without example how to write those kind of test. Elasticsearch Reference [1.6] » Testing » Java Testing Framework » integration tests
« unit tests
Also I found following article, but it's out of data. Easy JUnit testing with Elastic Search
I looking example how to start and run ES in-memory and access to it over REST API.
Based on the second link you provided, I created this abstract test class:
#RunWith(SpringJUnit4ClassRunner.class)
public abstract class AbstractElasticsearchTest {
private static final String HTTP_PORT = "9205";
private static final String HTTP_TRANSPORT_PORT = "9305";
private static final String ES_WORKING_DIR = "target/es";
private static Node node;
#BeforeClass
public static void startElasticsearch() throws Exception {
removeOldDataDir(ES_WORKING_DIR + "/" + clusterName);
Settings settings = Settings.builder()
.put("path.home", ES_WORKING_DIR)
.put("path.conf", ES_WORKING_DIR)
.put("path.data", ES_WORKING_DIR)
.put("path.work", ES_WORKING_DIR)
.put("path.logs", ES_WORKING_DIR)
.put("http.port", HTTP_PORT)
.put("transport.tcp.port", HTTP_TRANSPORT_PORT)
.put("index.number_of_shards", "1")
.put("index.number_of_replicas", "0")
.put("discovery.zen.ping.multicast.enabled", "false")
.build();
node = nodeBuilder().settings(settings).clusterName("monkeys.elasticsearch").client(false).node();
node.start();
}
#AfterClass
public static void stopElasticsearch() {
node.close();
}
private static void removeOldDataDir(String datadir) throws Exception {
File dataDir = new File(datadir);
if (dataDir.exists()) {
FileSystemUtils.deleteRecursively(dataDir);
}
}
}
In the production code, I configured an Elasticsearch client as follows. The integration test extends the above defined abstract class and configures property elasticsearch.port as 9305 and elasticsearch.host as localhost.
#Configuration
public class ElasticsearchConfiguration {
#Bean(destroyMethod = "close")
public Client elasticsearchClient(#Value("${elasticsearch.clusterName}") String clusterName,
#Value("${elasticsearch.host}") String elasticsearchClusterHost,
#Value("${elasticsearch.port}") Integer elasticsearchClusterPort) throws UnknownHostException {
Settings settings = Settings.settingsBuilder().put("cluster.name", clusterName).build();
InetSocketTransportAddress transportAddress = new InetSocketTransportAddress(InetAddress.getByName(elasticsearchClusterHost), elasticsearchClusterPort);
return TransportClient.builder().settings(settings).build().addTransportAddress(transportAddress);
}
}
That's it. The integration test will run the production code which is configured to connect to the node started in the AbstractElasticsearchTest.startElasticsearch().
In case you want to use the elasticsearch REST api, use port 9205. E.g. with Apache HttpComponents:
HttpClient httpClient = HttpClients.createDefault();
HttpPut httpPut = new HttpPut("http://localhost:9205/_template/" + templateName);
httpPut.setEntity(new FileEntity(new File("template.json")));
httpClient.execute(httpPut);
Here is my implementation

You can start ES on your local with:
Settings settings = Settings.settingsBuilder()
.put("path.home", ".")
.build();
NodeBuilder.nodeBuilder().settings(settings).node();
When ES started, access it over REST like:
http://localhost:9200/_cat/health?v
As of 2016 embedded elasticsearch is no-longer supported
As per a response from one of the devlopers in 2017 you can use the following approaches:
Use the Gradle tools elasticsearch already has. You can read some information about this here: https://github.com/elastic/elasticsearch/issues/21119
Use the Maven plugin: https://github.com/alexcojocaru/elasticsearch-maven-plugin
Use Ant scripts like http://david.pilato.fr/blog/2016/10/18/elasticsearch-real-integration-tests-updated-for-ga
Using Docker: https://www.testcontainers.org/modules/elasticsearch
Using Docker from maven: https://github.com/dadoonet/fscrawler/blob/e15dddf72b1ed094dad279d492e4e0314f73683f/pom.xml#L241-L289
I'm developing a client which should run in OSGi container. I'm using the stubs generated by cxf-codegen-plugin. The following Standalone application works fine:
public class MyClient {
public static void main(String args[]) throws java.lang.Exception{
String endpointT = "http://myService/endpoint/";
MyServicess = new MyService( );
MyServicePortType port = ss.MyServicePort();
BindingProvider provider = (BindingProvider) port;
Client client = ClientProxy.getClient(port);
client.getRequestContext().put(Message.ENDPOINT_ADDRESS, endpointT) ;
System.out.println("Invoking findEventManager...");
System.out.println(port.callService());
}
}
When I try the same thing in an OSGi container (I'm using karaf which use the felix implementation of OSGi). It doesn't work! and show me this excepption javax.xml.ws.WebServiceException: Could not find wsdl:binding operation info for web method callService. . The code looks as following:
#Component(name="RemoteExample", immediate=true)
#Service
public class RemoteExampleImpl extends Thread implements IRemoteExample {
private Boolean running =false;
#Activate
protected void activate(ComponentContext context) {
running =true;
this.start();
}
public void run() {
boolean cont = true;
while (cont && running) {
String endpointT = "http://myService/endpoint/";
MyServicess = new MyService( );
MyServicePortType port = ss.MyServicePort();
BindingProvider provider = (BindingProvider) port;
Client client = ClientProxy.getClient(port);
client.getRequestContext().put(Message.ENDPOINT_ADDRESS, endpointT) ;
System.out.println("Invoking findEventManager...");
System.out.println(port.callService());
}
}
#Deactivate
protected void deactivate(ComponentContext context) {
running = false;
mLogger.info("LocalExampleImpl deactivated");
}
}
How I can make this code work?
I try to create a soap UI WSDL Mock Service using the soapUI API. But there seems to be no documentation of the source code.
Has anyone done this before or something in that direction?
Ok, I can now answer myself ... :)
I created a unit test for this task:
private static WsdlProjectFactory wsdlProjectFactory;
private static WsdlInterfaceFactory wsdlInterfaceFactory;
#BeforeClass
public static void createFactories(){
wsdlProjectFactory = new WsdlProjectFactory();
wsdlInterfaceFactory = new WsdlInterfaceFactory();
}
#Before
public void deleteCreatedFiles() {
new File("global-groovy.log").delete();
new File("soapui-errors.log").delete();
new File("soapui.log").delete();
new File("test.xml").delete();
}
private WsdlProject project;
#Before
public void createProject() throws XmlException, IOException, SoapUIException {
project = wsdlProjectFactory.createNew();
}
#Test #Ignore
public void testWSDLInterfaceImporting() throws SoapUIException {
int interfaceCount = project.getInterfaceCount();
assertThat("newly created project has no interfaces", interfaceCount, is(equalTo(0)));
WsdlInterface[] importWsdl = wsdlInterfaceFactory.importWsdl(project, "wsdls/SimpleUseCasesellerbtainitialbtexampleMasterClient.wsdl", false);
interfaceCount = project.getInterfaceCount();
assertThat("newly created project has 1 interface", interfaceCount, is(equalTo(1)));
}
#Test
public void testMockCreation() throws XmlException, IOException, SoapUIException {
int mockCount = project.getMockServiceCount();
assertThat("newly created project has no mocks", mockCount, is(equalTo(0)));
WsdlInterface[] importWsdl = wsdlInterfaceFactory.importWsdl(project, "wsdls/SimpleUseCasesellerbtainitialbtexampleMasterClient.wsdl", false);
WsdlMockService service = project.addNewMockService("newMockService");
service.addNewMockOperation(importWsdl[0].getOperationAt(0));
project.saveAs("test.xml");
mockCount = project.getMockServiceCount();
assertThat("project has exactly one mock", mockCount, is(1));
}
