Kotlin integration tests for spring-boot

What I have: there is a microservice on Spring boot, with the web and MongoDB as a storage. For integration tests, I use test container. For testing the microservice, 2 intagration tests with SpringBootTest annatation are written, and for them there is a TestConfig class for raising the mongodb container.

What is the problem: if you run the tests individually, they pass, but if you run them simultaneously, they fall. 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() {}
}

The funny thing is that if you rewrite the tests and config in java, everything works)
