由于java.lang.outofmemoryerror，contextloads测试失败。

@RunWith(SpringRunner.class)
@SpringBootTest
public class MongoDbKafkaConsumerApplicationTests
{
    @Test
    public void contextLoads() throws Exception {

    }
}

@SpringBootApplication
public class MongoDbKafkaConsumerApplication
{

    public static void main(String[] args)
    {
        SpringApplication.run(MongoDbKafkaConsumerApplication.class, args);
    }
}

stacktrace如下：

org.springframework.context.ApplicationContextException: Failed to start bean 'org.springframework.kafka.config.internalKafkaListenerEndpointRegistry'; nested exception is java.lang.OutOfMemoryError: Java heap space

我正在使用Java11，还尝试在gradle.properties文件中设置org.gradle.jvmargs=-xmx1024m。我错过了什么？
附加信息：如果我删除@springboottest注解，测试就通过了。
为什么使用@springboottest时测试没有通过？

应用程序（@springbootapplication）和测试（@springboottest）运行同一个类。因此，当您运行该类时，您将加载应用程序两次（应用程序本身和测试注解创建的应用程序上下文），这很可能是内存不足错误的原因。以及为什么它可以在删除测试注解的情况下工作。它已经具有实际运行的应用程序的应用程序上下文。
