how to disable autoconfiguration in integration test? - spring

Question

I am trying this:
#SpringBootTest(
webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT,
)
#EnableAutoConfiguration(
exclude = [
ReactiveOAuth2ClientAutoConfiguration::class,
ReactiveOAuth2ResourceServerAutoConfiguration::class,
]
)
#ActiveProfiles("testcontainers")
internal class RecordIntegrationTest {
#Test
fun contextLoads() {}
}
With testcontainers profile in application.yml:
spring:
config.activate.on-profile: testcontainers
r2dbc.url: r2dbc:tc:postgresql:///databasename?TC_IMAGE_TAG=13.2
flyway:
enabled: false
But then it tries to create repositories twice (and potentially other beans as well):
java.lang.IllegalStateException: Failed to load ApplicationContext
...
Caused by: org.springframework.beans.factory.support.BeanDefinitionOverrideException: Invalid bean definition with name 'recordRepository' defined in com.example.RecordRepository defined in #EnableR2dbcRepositories declared on R2dbcRepositoriesAutoConfigureRegistrar.EnableR2dbcRepositoriesConfiguration: Cannot register bean definition [Root bean: class [org.springframework.data.r2dbc.repository.support.R2dbcRepositoryFactoryBean]; scope=; abstract=false; lazyInit=false; autowireMode=0; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=null; factoryMethodName=null; initMethodName=null; destroyMethodName=null; defined in com.example.RecordRepository defined in #EnableR2dbcRepositories declared on R2dbcRepositoriesAutoConfigureRegistrar.EnableR2dbcRepositoriesConfiguration] for bean 'recordRepository': There is already [Root bean: class [org.springframework.data.r2dbc.repository.support.R2dbcRepositoryFactoryBean]; scope=; abstract=false; lazyInit=false; autowireMode=0; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=null; factoryMethodName=null; initMethodName=null; destroyMethodName=null; defined in com.example.RecordRepository defined in #EnableR2dbcRepositories declared on R2dbcRepositoriesAutoConfigureRegistrar.EnableR2dbcRepositoriesConfiguration] bound.
UPDATE
Found out that the test runs fine when I move it to the root package
src/test/kotlin/com/example/backend
But it fails when I put it in the package
`src/test/kotlin/com/example/backend/subfolder`
UPDATE 2
I figured out that if a repository defined under src/main/kotlin is in the same package as the integration test that exception shows up.
E.g.:
data class X(#Id id: Long? = null)
// src/main/kotlin/com/example/x/XRepository.kt
interface XRepository : CoroutineCrudRepository<X, Long> {}
This test fails with the above exception:
// src/test/kotlin/com/example/x/XIntegrationTest.kt
#SpringBootTest(classes = [BackendApplication::class])
#EnableAutoConfiguration(
exclude = [
ReactiveOAuth2ClientAutoConfiguration::class,
ReactiveOAuth2ResourceServerAutoConfiguration::class,
]
)
#ActiveProfiles("testcontainers")
internal class XIntegrationTest {
#Test
fun contextLoads() {
}
}
Deleting the repository or moving the integration test to a different package works fine.

Answer 1

Include DataSourceAutoConfiguration in exclude block used by EnableR2dbcRepositories which disables the checking of datasource while starting up your integration test which is used by Repositories or you can configure the datasource to fix this issue.
The issue is basically due to the unavailability of datasource required by the repositories

Answer 2

Somewhere in your src/main/java you have a class that brings the annotation #EnableAutoConfiguration. This is the class that you want to exclude from your tests, when you have defined your own #EnableAutoConfiguration in some other class in test package.
