found multiple declarations of @BootstrapWith

Question

I'm using a base integration test with these annotations:

@ExtendWith(SpringExtension::class)
@SpringBootTest(classes = [SomeApplication::class], webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@DataMongoTest
@EmbeddedKafka(
        partitions = 3,
        controlledShutdown = false,
        brokerProperties = ["listeners=PLAINTEXT://127.0.0.1:9092", "port=9092"])
abstract class IntegrationTestBase {

When I run the test i get this error:

java.lang.IllegalStateException: Configuration error: found multiple declarations of @BootstrapWith for test class [com.some.app.application.restapi.DatabaseSetupApiEte]: [@org.springframework.test.context.BootstrapWith(value=org.springframework.boot.test.context.SpringBootTestContextBootstrapper), @org.springframework.test.context.BootstrapWith(value=org.springframework.boot.test.autoconfigure.data.mongo.DataMongoTestContextBootstrapper)]

The error is caused by both annotations @SpringBootTest and @DataMongoTest including @BootstrapWith like this:

@SpringBootTest has @BootstrapWith(SpringBootTestContextBootstrapper.class)

@DataMongoTest has @BootstrapWith(DataMongoTestContextBootstrapper.class)

I need to keep using @SpringBootTest for SpringBootTest.WebEnvironment.RANDOM_PORT but i also want the embedded mongodb from @DataMongoTest

Any suggestions?

I solved it by doing this:

@ExtendWith(SpringExtension::class)
@SpringBootTest(classes = [SomeAppApplication::class], webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
abstract class SomeAppSpringBootTest {

In cases where I want the mebedded mongodb to be used:

@EmbeddedKafka(
        partitions = 3,
        controlledShutdown = false,
        brokerProperties = ["listeners=PLAINTEXT://127.0.0.1:9092", "port=9092"])
abstract class IntegrationTestBase: SomeAppSpringBootTest() {

In the above you get the embedded mongodb by just including:

testCompile("de.flapdoodle.embed:de.flapdoodle.embed.mongo:2.2.0")

In cases where I don't wan't the embedded behaviour i use:

@TestPropertySource(properties = ["spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.mongo.embedded.EmbeddedMongoAutoConfiguration"])
abstract class EndToEndTestBase: SomeAppSpringBootTest()

So for each type of test i use the correct abstract base test class.

found multiple declarations of @BootstrapWith
