spring-boot - 使用 springboot 运行集成测试

问题描述

我有几个繁重的 Spring 集成测试（是的，这不是最好的方法，我没有时间正确模拟所有外部部门）

这是测试的典型注释


@ExtendWith(SpringExtension.class)
@AutoConfigureMockMvc
@EmbeddedKafka(
        partitions = 1,
        brokerProperties = {"log.dir=target/${random.int}/embedded-kafka/data"},
        topics = {
                "${service.topic}",
                "${service.dead-letter-topic}"
        })
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class OneOfMyHeavyintegrationTests extends DatabaseBackedTest {

// omitted for brevity
//
}

// foundation for DB in tests
@ContextConfiguration(initializers = DatabaseBackedTest.Initializer.class)
public abstract class DatabaseBackedTest {

    private static final EmbeddedPostgresInfo db = EmbeddedPostgresDatabase.create().start();

    static class Initializer implements ApplicationContextInitializer<ConfigurableApplicationContext> {
        @Override
        public void initialize(ConfigurableApplicationContext context) {
            TestPropertyValues.of("spring.datasource.url=" + db.getJdbcUrl()).applyTo(context.getEnvironment());
        }
    }

}

由于以下原因，测试会定期失败

22:14:51.463  [main] INFO  o.a.k.common.utils.AppInfoParser - Kafka commitId : fa14705e51bd2ce5

    at kafka.utils.TestUtils.createServer(TestUtils.scala)

有两个问题：1.让测试共存的正确方法是什么？我设置forkCount=0了surefire插件。似乎有帮助

在开始测试之前mock/组件的正确方法是什么？disable

2.1。我真的不需要@Scheduled @Component在每次测试期间都开始

2.2. 我真的不需要在每次测试时启动 Kafka 消费者

谢谢！
