The rabbitmq is configured but not in the test
In spring boot 3 with same code, rabbitmq only connect and disconnect on the whole test once
I am wondering why, and how to change back its behavior? Hopefully I am not missing something in the boot 4 migration guide

rabbitmq configuration:

@Configuration
class RabbitConfig {

    @Bean
    fun rabbitTemplate(connectionFactory: ConnectionFactory): RabbitTemplate {
        initQueues(connectionFactory)
        return RabbitTemplate(connectionFactory)

            connection.createChannel(false).use { channel ->
                channel.queueDeclare(DemoListener.QUEUE_NAME, true, false, false, null)
            }
        }
    }
}

listener:

@Component
class DemoListener {

    companion object {
        const val QUEUE_NAME = "demo.queue"
    }

    @RabbitListener(queues = [QUEUE_NAME])
    fun onMessage(message: String) {
        println("Received: $message")
    }
}

test base class:

@ActiveProfiles("test")
@SpringBootTest
@ContextConfiguration(initializers = [BaseTest.Initializer::class])
abstract class BaseTest {

    companion object {
        val rabbitMQContainer: RabbitMQContainer = RabbitMQContainer(DockerImageName.parse("rabbitmq:3.13"))

        init {
            rabbitMQContainer.start()
        }
    }

    internal class Initializer : ApplicationContextInitializer<ConfigurableApplicationContext> {
        override fun initialize(context: ConfigurableApplicationContext) {
            TestPropertyValues.of(
                "spring.rabbitmq.host=${rabbitMQContainer.host}",
                "spring.rabbitmq.port=${rabbitMQContainer.amqpPort}",
                "spring.rabbitmq.username=${rabbitMQContainer.adminUsername}",
                "spring.rabbitmq.password=${rabbitMQContainer.adminPassword}",
            ).applyTo(context.environment)
        }
    }
}

test class:

class FirstTest : BaseTest() {

    @Test
    fun test1() {
        println("=== FirstTest.test1 running ===")
        assertTrue(true)
    }

    @Test
    fun test2() {
        println("=== FirstTest.test2 running ===")
        assertTrue(true)
    }
}

Sorry for my bad English

I believe this has nothing to do with Spring AMQP or RabbitMQ at all.
Looks like in Spring Boot 3.5.x, all the test classes use the same cached application context, while in Spring Boot 4.0.x they are no for some reason.
Might even the case that it even has nothing to do with Spring Boot, but just Spring Framework 6.5.x vs 7.0.x.

Would you mind to investigate to that direction?
I mean without AMQP stuff or even Spring Boot?

Thanks

Thank you very much! Will look into that direction

Thank you that I have found the issue but I have no idea how to workaround it.
Spring Framework 7 introduces Pausing of Test Application Contexts and reference for it.
This change is causing rabbitmq connect and disconnect on every test class as SmartLifecycle#isPauseable() by default is true
For me, the real problem is this connect and disconnect behavior takes about 1 second to happen even against local rabbitmq, which make my tests using too much time if this is needed on every test class
Do you have any suggestions? much thanks @artembilan

See here: spring-projects/spring-framework#36044.
I guess no solution yet.
You may try to extend CachingConnectionFactory to override its isPauseable() for now.
