I am working on moving my kafa CDC application to spring boot 2.6.* . But when I upgrade to spring boot 2.6.*, Junit tests are failing with following error
CdcConsumerApplicationTest > testMainApplicationLoad() FAILED
java.lang.IllegalStateException at DefaultCacheAwareContextLoaderDelegate.java:132
Caused by: java.lang.IllegalStateException at SpringBootCondition.java:60
Caused by: java.lang.ArrayStoreException at AnnotationParser.java:724
This is simple Junit example test that is failing
#SpringBootTest
#ActiveProfiles("test")
#ContextConfiguration(classes = { AppTestConfiguration.class })
#EmbeddedKafka(partitions = 1, topics = { "XXX.SOME-DB2-CHANGE" })
public class CdcConsumerApplicationTest {
#Test
public void testMainApplicationLoad() {
}
}
If I run this tests locally on my IDE, they works fine but they are failing when running via jenkins. All my Junits are junit 5. Anything I am missing or I need to change when moving from spring boot 2.5 to 2.6 and further ?

Trying to run a very simple Spring Boot 3 app on GraalVM. The app just stores some data in H2 on startup. It is basically the same as what Josh does in the Spring Tips about Ahead-of-Time compilation, but using Kotlin instead of Java.
When starting the native image, I get the following error after Spring startup:
java.lang.UnsupportedOperationException: Kotlin class com.example.demo.basics.Customer has no .copy(…) method for property id
at org.springframework.data.mapping.model.BeanWrapper$KotlinCopyUtil.setProperty(BeanWrapper.java:171) ~[na:na]
at org.springframework.data.mapping.model.BeanWrapper.setProperty(BeanWrapper.java:79) ~[na:na]
...
I'm pretty new to GraalVM and Spring Native Images, don't know if I am missing something basic which needs to be configured when using Kotlin with Spring. The missing copy methods for the data class should have been generated by Kotlin, so I guess something is left out by the native compile related to Kotlin specifically.
The code which fails is the following class:
#Configuration
class BasicsConfiguration {
#Bean // execute on application start
fun basicsApplicationListener(customerRepository: CustomerRepository): ApplicationListener<ApplicationReadyEvent> {
return ApplicationListener<ApplicationReadyEvent> {
// store some values in the database
customerRepository
.saveAll(listOf("A", "B", "C").map { Customer(null, it) })
.forEach { println(it) }
}
}
}
interface CustomerRepository : CrudRepository<Customer, Int>
data class Customer(#Id val id: Long?, val name: String)
Running the app on the JDK works perfectly fine: ./gradlew bootRun
2022-11-30T11:23:15.300+01:00 INFO 33997 --- [ main] com.example.demo.DemoApplicationKt : Started DemoApplicationKt in 2.383 seconds (process running for 2.733)
Customer(id=1, name=A)
Customer(id=2, name=B)
Customer(id=3, name=C)
The native image is also created successfully: ./gradlew nativeCompile
Starting the native image works, the server process starts up but then fails:
2022-11-30T11:08:11.085+01:00 INFO 33059 --- [ main] com.example.demo.DemoApplicationKt : Started DemoApplicationKt in 0.147 seconds (process running for 0.158)

Seems like this is an issue with Spring Data, which is not providing all necessary reflection hints for the native image creation. Specifically the reflection configuration for data classes' copy$default methods are missing. Will (probably) be fixed with Spring 6.0.3 release, see this issue for details: https://github.com/spring-projects/spring-framework/issues/29593
Workaround: add something like this in your reflect-config.json for the given data class:
{
"name": "copy$default",
"parameterTypes": [
"com.example.demo.basics.Customer",
"java.lang.Long",
"java.lang.String",
"int",
"java.lang.Object"
]
}
I am trying to use spring cloud contracts for messaging.
I have a producer and a consumer who is publishing and consuming from rabbitmq.
they are working fine when I run both these spring boot applications.
however, when I try to mvn clean install , generated ContractVerifierTest fails with the error

I have spring-cloud-stream, spring-cloud-stream-binder-rabbit, spring-cloud-starter-contract-verifier, spring-cloud-stream:test-binder dependencies in my pom as well.
My spring boot application class is configured like this
#SpringBootApplication
#EnableBinding(Source.class)
public class ProducerApplication {
It is sending the message to the destination topic from tests as well. However, it fails to read it
#Test
public void validate_contract_name() throws Exception {
// when:
trigger(); // this happens fine
// then:
ContractVerifierMessage response = contractVerifierMessaging.receive("destination-name",
contract(this, "contract_name.yml")); // THIS FAILS
assertThat(response).isNotNull();
I have annotated my base test class with these
#SpringBootTest(classes = ProducerApplication.class, webEnvironment = SpringBootTest.WebEnvironment.NONE)
#ExtendWith(SpringExtension.class)
#AutoConfigureMessageVerifier
I have verified that OutputDestination class is available in the classpath.
I have org.springframework.cloud:spring-cloud-stream:test-jar:test-binder:3.2.1:test in the classpath.
spring-boot-starter-parent version is 2.6.2. spring cloud version is 2021.0.0
I have configured spring-cloud-contract-maven-plugin version 3.1.0 to use JUNIT5
What I have: I'm developing a microservice, using Spring Boot with Web and MongoDB as storage. For CI integration tests I use test containers. I have two integrations tests with SpringBootTest annotations, which use TestConfig class. TestConfig class provides setup MongoDB test container with fixed exposed ports.
My problem: When I run my tests one at a time then they succeed. But when I run my tests at the same time then they failed.
MongoContainerConfig.kt
#TestConfiguration
class MongoContainerConfig {
var mongoContainer: GenericContainer<Nothing>
constructor() {
mongoContainer = FixedHostPortGenericContainer<Nothing>("mongo")
.withFixedExposedPort(27018,27017)
mongoContainer.start()
}
#PreDestroy
fun close() {
mongoContainer.stop()
}
}
First test
#SpringBootTest(
classes = arrayOf(MongoContainerConfig::class, AssertUtilsConfig::class),
webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT
)
class CardControllerTest {
#Test
fun test() {}
}
Second test
#SpringBootTest(classes = arrayOf(MongoContainerConfig::class, AssertUtilsConfig::class))
class PositiveTest {
#Test
fun test() {}
}

This project you can see on github with CI
https://github.com/GSkoba/eng-card/runs/576320155?check_suite_focus=true
It's very funny because tests work if rewrite them to java
Hah, it not easy)
https://docs.spring.io/spring/docs/5.2.5.RELEASE/spring-framework-reference/testing.html#testcontext-ctx-management-caching
Tests have different context and its why MongoContainerConfig call twice.
Fix - add webEnv as in CardControllerTest.kt
#SpringBootTest(classes = arrayOf(MongoContainerConfig::class, AssertUtilsConfig::class),
webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
class PositiveTest

I'm very new to junit testing. How to write junit test real database call from mybatis.xml file.
Please find the below code.
#RunWith(SpringRunner.class)
//#MybatisTest
#SpringBootTest
public class HotelMapperTest {
#Autowired
private HotelMapper hotelMapper;
#Test
public void selectByCityIdTest() {
Hotel hotel = hotelMapper.selectByCityId(1);
assertThat(hotel.getName()).isEqualTo("Conrad Treasury Place");
assertThat(hotel.getAddress()).isEqualTo("William & George Streets");
assertThat(hotel.getZip()).isEqualTo("4001");
}
when i run the junit testing i'm getting below exception:
org.apache.ibatis.binding.BindingException: Invalid bound statement (not found):
Herer my question is how we'll test the real database, When enable the #MybatisTest it's looking for datasource, already we specified all properties in applicaiton.properties. In this time i'm getting below exception:
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource':
You can config mybatis mapper location in spring configuration file (such as application.yml).
mybatis configuration:
mybatis:
mapper-locations:
- classpath*:mapper/*.xml
Switching from spring boot back to "normal" spring because the app only uses some jdbc code to "upsert" into a postgresql database.
1)
tried annotating the test class with:
#RunWith(SpringJUnit4ClassRunner.class)
public class DBIntegration {
results in:
java.lang.IllegalStateException: Failed to load ApplicationContext
2)
tried annotating the class with:
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(locations = {})
public class DBIntegration {

No exceptions, but java.lang.Exception: No tests found matching [{ExactMatcher:fDisplayName=insertDataFrom_sometest],
3) tried annotating the class with:
#Component
public class DBIntegration {
dependency injection does not work in this case, the expected service
(to be injected) throws a nullpointerexception
