this is my first class to start the application
#SpringBootApplication
#ComponentScan
public class PosApplication {
public static void main(String[] args) {
SpringApplication.run(PosApplication.class, args);
}
}
This is my second class and bean is defined and throgh testNGRunner method it will call Testme class
#Configuration
public class WebDriverLibrary {
#Bean
public void testNGRunner()
{
TestNG testng=new TestNG();
XmlSuite suite=new XmlSuite();
List<XmlSuite> suites=new ArrayList<XmlSuite>();
suites.add(suite);
List<XmlClass> clazzes=new ArrayList<XmlClass>();
XmlClass clazz=new XmlClass("com.pos.Testme");
clazzes.add(clazz);
XmlTest test=new XmlTest(suite);
test.setClasses(clazzes);
testng.setXmlSuites(suites);
testng.run();
}
}
this is my 3rd class and here i have autowired TestDemo Class and problem in this class. My Testme class run successfully but TestDemo is get autowired dependancy as null.
public class Testme {
#Autowired TestDemo test; // here i am getting null for test
#Test
public void Print() {
System.out.println("Helo my child");
}
#BeforeTest
public void suite() {
System.out.println("MY Suite");
test.launchBrow();
}
#Component
public class TestDemo {
public void launchBrow()
{
System.out.println("Hit the Url");
}
}

My service
#Service
public class StripeServiceImpl implements StripeService {
#Override
public int getCustomerId() {
return 2;
}
}
My test
public class StripeServiceTests {
#Autowired
StripeService stripeService;
#TestConfiguration
static class TestConfig {
#Bean
public StripeService employeeService() {
return new StripeServiceImpl();
}
}
#Test
public void findCustomerByEmail_customerExists_returnCustomer() {
assertThat(stripeService.getCustomerId()).isEqualTo(2);
}
}
The error: java.lang.NullPointerException. I had checked and the stripeService is actually null.
Since you are autowiring you need an applicationcontext so that Spring can manage the bean and then can get injected in your class. Therefore you are missing an annotation to create the applicationcontext for your testclass.
I have updated your code and it works now(with junit 5 on your classpath). In the case dat you are using junit 4 it should be #RunWith(SpringRunner.class) instead of #ExtendWith(SpringExtension.class):
#ExtendWith(SpringExtension.class)
#ContextConfiguration(classes = TestConfiguration.class)
public class StripeServiceTests {
#Autowired
StripeService stripeService;
#TestConfiguration
static class TestConfig {
#Bean
public StripeService employeeService() {
return new StripeServiceImpl();
}
}
#Test
public void findCustomerByEmail_customerExists_returnCustomer() {
assertThat(stripeService.getCustomerId()).isEqualTo(2);
}
}
I wrote an ApplicationListener that should check if the environment is prepared during context initialization. I'm having trouble testing the scenario since I'm adding the listener manually both in my configure() and main() methods.
ApplicationListener class:
public class EnvironmentPrepared implements ApplicationListener<ApplicationEnvironmentPreparedEvent> {
#Override
public void onApplicationEvent(ApplicationEnvironmentPreparedEvent event) {
//code that checks if conditions are met
if (checkTrue) {
throw new RuntimeException();
}
}
}
Main class:
public class MyApp extends SpringBootServletInitializer {
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
setRegisterErrorPageFilter(false);
return application.listeners(new EnvironmentPrepared()).sources(MyApp.class);
}
public static void main(String[] args) {
SpringApplication springApplication = new SpringApplication(MyApp.class);
springApplication.addListeners(new EnvironmentPrepared());
springApplication.run(args);
}
}
The test I want to execute:
#RunWith(SpringRunner.class)
#SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
#ContextConfiguration(loader = OverriddenProfilesTest.CustomLoader.class)
public class OverriddenProfilesTest {
public static class CustomLoader extends SpringBootContextLoader {
#Override
protected SpringApplication getSpringApplication() {
SpringApplication app = super.getSpringApplication();
app.addListeners(new EnvironmentPrepared());
return app;
}
}
/**
* Checks if spring can bootstrap everything
*/
#Test(expected = RuntimeException.class)
public void test() {
}
}
This would be the test I want. A RuntimeException is thrown but the exception happens during context initialization so the test doesn't even start.
Here is the solution I used. I removed the manual adding of the listener to the application and used spring.factories file instead.
Regarding the test, I first created a custom runner class:
public class SpringRunnerWithExpectedExceptionRule extends SpringJUnit4ClassRunner {
public SpringRunnerWithExpectedExceptionRule(Class<?> clazz) throws InitializationError {
super(clazz);
}
#Override
protected Statement methodBlock(FrameworkMethod frameworkMethod) {
List<ExpectedException> testRules = getTestClass().getAnnotatedFieldValues(null, ExpectedExceptionClassRule.class, ExpectedException.class);
Statement result = super.methodBlock(frameworkMethod);
for (TestRule item : testRules) {
result = item.apply(result, getDescription());
}
return result;
}}
Then I create following annotation:
#Retention(RUNTIME)
#Target({ FIELD })
public #interface ExpectedExceptionClassRule {
}
And finally, I was able to run the test with my runner:
#RunWith(SpringRunnerWithExpectedExceptionRule.class)
#SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class OverriddenProfilesTest {
#ExpectedExceptionClassRule
public static ExpectedException expectedException = ExpectedException.none();
#BeforeClass
public static void before() {
expectedException.expectCause(runtimeExceptionMethod());
}
#Test
public void testThatShouldThrowExceptionWhileSettingContext {
}
static Matcher<Throwable> runtimeExceptionMethod() {
return new IsRuntimeException();
}
static class IsRuntimeException extends TypeSafeMatcher<Throwable> {
//do stuff
}

wanner test spring boot(1.5.20) aop with minimum code

#Autowired
private Test test;
#Override
public void run(String... strings) throws Exception {

}
}
both Test bean and LoggingAspect bean is created. Test.pring is executed. However, the pointcut log() is never triggered. I searched so and found no answer. I also tried #EnableAspectJAutoProxy with proxyTargetClass = True or False. In my understanding this params force to use cglib for Test class.
please let me know what I missed
figure out. change from .Test. to com.example.aop.Test.*, then works.
I tried to add some entities in the db shema
config:
#Configuration
#ComponentScan(ApplicationConfig.basePackage)
public class ApplicationConfig {
public final static String basePackage = "test"
}
spring container invocation:
public class StartApp {
public static void main(String... args) throws Exception{
ApplicationContext context = new AnnotationConfigApplicationContext(ApplicationConfig.class);
TestEntityRepository repository = (TestEntityRepository) context.getBean("testEntityRepository");
repository.save(new TestEntity("test"));
}
}
target class with annotation:
public class PersistenceService {
#Autowired
TestEntityRepository testEntityRepository;
#PostConstruct
public void initialize(){
//repository.deleteAll();
testEntityRepository.save(new TestEntity("test1"));
testEntityRepository.save(new TestEntity("test2"));
testEntityRepository.save(new TestEntity("test3"));
}
}
as the result in table only one record - "test". At the Tomcat all works fine.

It seems your PersistenceServiceis not recognized as a Service. Can you add the #Service to PersistenceService?
#Service
public class PersistenceService {
...
}
Hope this help.
I am using spring boot 1.4,
when using the #SpringBootTest annotation for integration test, it gives a null pointer.
#RunWith(SpringRunner.class);
#SpringBootTest
public class MyControllerTest {
#Test
public void mytest {
when().
get("/hello").
then().
body("hello");
}
}
and for main class:
#SpringApplication
#EnableCaching
#EnableAsync
public class HelloApp extends AsyncConfigureSupport {
public static void main(String[] args) {
SpringApplication.run(HelloApp.class, args);
}
#Override
public Executor getAsyncExecutor() {
...
}
}
Then in my controller:
#RestController
public class HelloController {
#Autowired
private HelloService helloService;
#RequestMapping("/hello");
public String hello() {
return helloService.sayHello();
}
}
HelloService
#Service
public class HelloService {
public String sayHello() {
return "hello";
}
}
But it ways says NullPointException when for helloService when processing request.
What am I missing?
You need to mock HelloService in your test class as your controller is calling a service .Here in your case Your Test class is not aware that there is any service available or not
The following example test class might help you. In this guide from spring an example is shown how to integration test a rest controller in a spring fashion way.
#RunWith(SpringRunner.class)
#SpringBootTest
#WebAppConfiguration
public class HelloControllerTest {
private MockMvc mockMvc;
#Autowired
private WebApplicationContext webApplicationContext;
#Before
public void setUp() {
this.mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
}
#Test
public void hello() throws Exception {
mockMvc.perform(get("/hello")).andExpect(content().string("hello"));
}
}
