I try testing my LocalServiceUtil classes, generated by service builder, with PowerMock but always getting 'null' or '0' from Util's methods.
Test class
#RunWith(PowerMockRunner.class)
#PrepareForTest(EntityLocalServiceUtil.class)
public class EntityTest {
#Test
public void testGetAnswer() throws PortalException, SystemException {
PowerMockito.mockStatic(EntityLocalServiceUtil.class);
assertEquals("hello", EntityLocalServiceUtil.getHello());
}
}
Util class contains
public static java.lang.String getHello() {
return getService().getHello();
}
and this service working correctly on deployed portlet. What i do wrong?
You have forgot to mock the methode:
#Test
public void testGetAnswer() throws PortalException, SystemException {
PowerMockito.mockStatic(EntityLocalServiceUtil.class);
when(EntityLocalServiceUtil.getHello()).thenReturn("hello"); // <- here
assertEquals("hello", EntityLocalServiceUtil.getHello());
}

I am writing a JUnit test case for the controller in my micronaut application. The controller has a GET endpoint which invokes a method in my service class. I am getting a NullPointerException so I am assuming that my service class might not be properly mocked however, I am not sure. I am using #Mock (Mockito) for the service.
Am I using the correct annotation to mock the service layer? I have tried to search on google but it hasn't given me much to look into. Thanks.
#MicronautTest
public class FPlanControllerTest {
private static final String url = "dummy_url";
#Inject
FPlanService fplanService;
#Inject
#Client("/")
RxHttpClient client;
#Test
public void testGetLayout() {
FPlanUrl expectedFPlanUrl = new FPlanUrl(url);
when(fplanService.getLayoutUrl(Mockito.anyString(), Mockito.anyString()))
.thenReturn(expectedFPlanUrl);
FPlanUrl actualFPlanUrl = client.toBlocking()
.retrieve(HttpRequest.GET("/layout/1000545").header("layoutId", "7"), FPlanUrl.class);
assertEquals(expectedFPlanUrl , actualFPlanUrl);
}
#MockBean(FPlanService.class)
FPlanService fplanService() {
return mock(FPlanService.class);
}
}
I received the below error.
java.lang.NullPointerException at com.apartment.controller.FPlanControllerTest.testGetLayout(FPlanControllerTest.java:44)
Use #MockBean (io.micronaut.test.annotation.MockBean).
Docs - https://micronaut-projects.github.io/micronaut-test/latest/guide/#junit5
Simply try to mock as below :-
#MockBean(MyService.class)
MyService myService() {
return mock(MyService.class);
}
Now the service can be injected as:-
#Inject
private MyService myService;
Use inside your test method as:-
#Test
public void myServiceTest() {
when(myService.foo(any())).thenReturn(any());
MutableHttpResponse<FooResponse> response = controller.bar(new
MyRequest());
Assertions.assertNotNull(response);
}
I figured out what went wrong. This was giving a NullPointerException because the HTTP response was expecting a String and not the FPlanUrl object. The correct code is as below:
#Test
public void testGetLayout() {
FPlanUrl expectedFPlanUrl = new FPlanUrl("http://dummyurl.com");
when(fplanService.getLayoutUrl(Mockito.anyString(), Mockito.anyString()))
.thenReturn(expectedFPlanUrl);
Assertions.assertEquals("{\"url\":\"http://dummyurl.com\"}", client.toBlocking().retrieve(HttpRequest.GET("/layout/123").header("layoutId", "7"), String.class);
verify(fplanService).getLayoutUrl("123","7");
}
When trying to use #AutoWire feature with one of StandAlone Application unable to do so instead getting Null Pointer Exception. Please highlight my mistakes if any. Your help is appreciated.
Spring Ver 5.1.5.RELEASE and we're not using any xml config file to tell spring there are annotated classes to look into instead using #ComponentScan or #EnableAutoConfiguration at the top of AppConfig and boost strap the Context from main() class as a first line. But Autowiring works perfectly with internal bean/java classes of jdk(Environment) but not with custom POJO classes. If we're trying to get through getBean method then it works. But I'm trying to avoid creating context everywhere and using getBean() Please Refer below and help me only with your valuable guidelines.
public class ContextMaster {
private static AnnotationConfigApplicationContext appContext;
public static AnnotationConfigApplicationContext getApplicationContext() {
if (appContext == null) {
appContext = new AnnotationConfigApplicationContext(ContextConfig.class);
//appContext = new AnnotationConfigApplicationContext("com.xx.xx.xxx","xx.xxx.xxxx.xxx.datamanager");
logger.debug("Context Invoked !!");
}
return appContext;
}
}
#Configuration
#EnableAutoConfiguration
#PropertySource("classpath:db.properties")
#EnableTransactionManagement
#ComponentScans(value = {
#ComponentScan(basePackages = "xxxxx.datamanager"),
#ComponentScan(basePackages = "com.xx.xx.xxx"),
#ComponentScan(basePackages = "com.xx.xx.xxx.utils")})
public class AppConfig {
#Autowired
private Environment env;
#Bean
public DataSource getDataSource() {
BasicDataSource dataSource = new BasicDataSource();
dataSource.setDriverClassName(env.getProperty("db.driver"));
dataSource.setUrl(env.getProperty("db.url"));
return dataSource;
}
#Bean
public LocalSessionFactoryBean getSessionFactory() {
LocalSessionFactoryBean factoryBean = new LocalSessionFactoryBean();
//LocalSessionFactoryBean sessionFactoryBean = new AnnotationSessionFactoryBean();
factoryBean.setDataSource(getDataSource());
Properties props=new Properties();
props.put("hibernate.show_sql", env.getProperty("hibernate.show_sql"));
props.put("hibernate.hbm2ddl.auto", env.getProperty("hibernate.hbm2ddl.auto"));
props.put("hibernate.cache.region.factory_class", env.getProperty("hibernate.cache.region.factory_class"));
factoryBean.setHibernateProperties(props);
factoryBean.setAnnotatedClasses(xx.class, xxxx.class, xxxx.class, xxx.class);
return factoryBean;
}
#Bean
public HibernateTransactionManager getTransactionManager() {
return transactionManager;
}
}
// Here is NPE thrown when tried with auto-configured bean
#Component
public class Good extends Good11 {
#Autowired
private RxxxDyyyyHelper rdh;
//RxxxDyyyyHelper rdh =
ContextHelper.getApplicationContext().getBean(RxxxDyyyyHelper .class);
rdh.setProperty(); // NPE here
rdh.getProperty(); // NPE
}
// Here we're trying to initiate the LosUtils class
public class LosUtils {
public static void main(String args[]) throws Exception {
AnnotationConfigApplicationContext applicationContext = `ContextHelper.getApplicationContext();`
}
It seems like you didn't put the full code here, because your Good class won't compile this way..
I'm trying to use arquillian to test one method of an EJB using a webservice through #WebServiceRef annotation
In my method decorated by #Deployment I declared the resource
#Deployment
public static JavaArchive createDeployment() {
return ShrinkWrap.create(JavaArchive.class)
.addPackages(true, .... PortType.class.getPackage())
.addAsResource("test-my.wsdl","my.wsdl")
.addAsManifestResource("META-INF/beans.xml", "beans.xml").addAsManifestResource("META-INF/test-persistence.xml", "persistence.xml");
}
Then I coded the bean as following
#Stateless
#LocalBean
public class WSBean {
#WebServiceRef(wsdlLocation = "/my.wsdl")
PortType portType;
public void test() throws Exception{
portType.lireAdresseClient(null, null);
}
}
and the test
#RunWith(Arquillian.class)
public class WSintegrationTest extends DefaultServicesIntegrationTest {
#Deployment
....
#Inject
private WSBean wsBean;
#Test
public void testAppel() throws Exception {
System.out.println("TEST APPEL");
wsBean.test();
}
}
Can I do that with Arquillian ?
How can I fix it ?
Thanks

Also if you want you can take a look at https://github.com/javaee-samples/javaee7-samples/tree/master/jaxws you will find examples of JAXWS with its Arquillian test.
Is it possible to create spy(mock) object in testing class?
Here is tested class.
#Stateless
#Slf4j
public class UserDao {
#Inject
private TestBean testBean;
public String mock() {
return testBean.mock();
}
public String notMock() {
return testBean.notMock();
}
}
TestBean code
#Stateless
#Slf4j
public class TestBean {
public String notMock() {
return "NOT MOCK";
}
public String mock() {
return "IMPLEMENTED MOCK";
}
}
Here's my test
#RunWith(Arquillian.class)
public class UserDataTest {
#Rule
public ExpectedException thrown = ExpectedException.none();
#Inject
private UserDao userDao;
#Deployment
protected static Archive createWar() {
File[] dependencies = Maven.configureResolver()
.withRemoteRepo("nexus-remote", "http://maven.wideup.net/nexus/content/groups/public/", "default")
.withRemoteRepo("nexus-release", "http://maven.wideup.net/nexus/content/repositories/releases/", "default")
.resolve(
"org.slf4j:slf4j-simple:1.7.7",
"eu.bitwalker:UserAgentUtils:1.15",
"org.mockito:mockito-all:1.10.8"
).withoutTransitivity().asFile();
return ShrinkWrap
.create(WebArchive.class, "pass.jpa.war")
.addAsWebInfResource("jbossas-ds.xml")
.addAsWebInfResource("jboss-deployment-structure.xml")
.addAsLibraries(
PassApiDeployments.createDefaultDeployment(),
PassUtilLibrary.createDefaultDeployment(),
PassJpaDeployments.createDefaultDeployment()
).addAsLibraries(dependencies);
}
#Test
public void testMock() {
assertEquals("MOCK", userDao.mock());
}
#Test
public void testNotMock() {
assertEquals("NOT MOCK", userDao.notMock());
}
}
I'd like to create a spy object on TestBean to change result on method test() of this bean.
So is it possible to create TestBean spy in UserDao.
I solve some problems through producer like this.
#Singleton
public class MockFactory {
#Produces
#ArquillianAlternative
public TestBean getTestBean() {
return when(mock(TestBean.class).mock()).thenReturn("MOCK").getMock();
}
}
But in this example I need create on Bean completely on my own. And if it is bean with additional dependencies and thus i will manage all dependencies.
As far as I know, its not possible to use a mocking framework in combination with arquillian ...
I haven't used it myself, but this Arquillian extension seems to be specifically designed to support Mockito Spy objects in an Arquillian test: https://github.com/topikachu/arquillian-extension-mockito/
New poster here, hope I don't brake any rules :)
I am using PrivateModule in google-guice in order to have multiple DataSource's for the same environment. But I am having a hard time getting MethodInterceptor's to work inside the private modules.
Below is a simple test case that explains the "problem".
A simple service class would be:
interface Service {
String go();
}
class ServiceImpl implements Service {
#Override #Transactional
public String go() {
return "Test Case...";
}
}
The MyModule class would be:
class MyModule extends AbstractModule {
#Override
protected void configure() {
install(new PrivateModule() {
#Override
protected void configure() {
bind(Service.class).to(ServiceImpl.class);
bindInterceptor(
Matchers.any(),
Matchers.annotatedWith(Transactional.class),
new MethodInterceptor() {
#Override
public Object invoke(MethodInvocation i)
throws Throwable {
System.out.println("Intercepting: "
+ i.getMethod().getName());
return i.proceed();
}
});
expose(Service.class);
}
});
}
}
And the final test case:
public class TestCase {
#Inject Service service;
public TestCase() {
Guice.createInjector(new MyModule()).injectMembers(this);
}
public String go() {
return service.go();
}
public static void main(String[] args) {
TestCase t = new TestCase();
System.out.println(t.go());
}
}
You would expect the output to be:
Intercepting: go
Test Case...
But it doesn't happen, the interceptor is not used, ant only Test Case... is output.
If I bind/expose the ServiceImpl instead of the interface then it works.
Thanks in advance,
Regards,
LL
Well... I figured it out shortly after I posted the question :)
The problem is that you also need to expose() the ServiceImpl class.
So the bind/expose would be.
bind(ServiceImpl.class); // ServiceImpl annotated with #Singleton
bind(Service.class).to(ServiceImpl.class);
expose(ServiceImpl.class);
expose(Service.class);
Regards,
LL
You need to explicitly bind ServiceImpl in the private module. The problem with your existing code is that it inherits the binding for ServiceImpl from the parent module. From the PrivateModule docs,
Private modules are implemented using parent injectors. When it can satisfy their dependencies, just-in-time bindings will be created in the root environment. Such bindings are shared among all environments in the tree.
Adding this line should fix the problem:
bind(ServiceImpl.class);
