我有一个使用 TestContainers 的抽象类 BaseIntegrationTest。问题是当我尝试运行像 UserRepositoryIntSpec 这样的简单数据库测试时，我遇到了一个异常，这意味着计数从 114 开始，而不是像预期的那样从 1 开始。为什么索引不是从 1 开始？为什么每次执行设置时我的本地数据库用户表都很清楚，因为我希望测试在容器中使用容器数据库运行，所以只会清除容器表。这绝对应该是我刚刚错过或不理解的简单事情。我将不胜感激。

对于迁移，我使用 Flyway 来测试 Spock。

不满足条件：

user1.getId() == 1 && user1.getRiskcustomerid() == 1 && user1.getDateCreated() != null
|     |       |    |                                 |
|     114     |    false                             false
|             false

基础集成测试 

@ContextConfiguration
@SpringBootTest(webEnvironment = DEFINED_PORT)
@Testcontainers
@Slf4j
abstract class BaseIntegrationTest extends Specification {

protected static PostgreSQLContainer postgres = new PostgreSQLContainer()
        .withDatabaseName("db")
        .withUsername("root")
        .withPassword("root")

def setupSpec() {
    startPostgresIfNeeded()
    ['spring.datasource.url'     : postgres.getJdbcUrl(),
     'spring.datasource.username': postgres.getUsername(),
     'spring.datasource.password': postgres.getPassword()
    ].each { k, v ->
        System.setProperty(k, v)
    }
}

private static void startPostgresIfNeeded() {
    if (!postgres.isRunning()) {
        log.info("[BASE-INTEGRATION-TEST] - Postgres is not started. Running...")
        postgres.start()
    }
}

def cleanupSpec() {
    if (postgres.isRunning()) {
        log.info("[BASE-INTEGRATION-TEST] - Stopping Postgres...")
        postgres.stop()
    }
}
}

UserRepositoryIntSpec

class UserRepositoryIntSpec extends BaseIntegrationTest {

    @Autowired
    private UserRepository UserRepository

    def setup() {
        UserRepository.deleteAll()
    }

    def "FindAll returns all users correctly"() {
        given:
        List<Integer> friends = [1,2]
        User User1 = User.builder()
                .riskcustomerid(1)
                .possibleids([1000, 1001])
                .preferableid(1000)
                .totalfriendscount(2)
                .friends(friends)
                .build()
        User User2 = User.builder()
                .riskcustomerid(2)
                .possibleids([8000, 8001])
                .preferableid(8000)
                .totalfriendscount(3)
                .friends(friends)
                .build()

        when:
        UserRepository.saveAll([User1, User2])

        then:
        List<User> Users = UserRepository.findAll()
        assert Users.size() == 2
        User user1 = Users.get(0)
        User user2 = Users.get(1)
        assert user1.getId() == 1 && user1.getRiskcustomerid() == 1 && user1.getDateCreated() != null
        assert user2.getId() == 2 && user2.getRiskcustomerid() == 2 && user2.getDateCreated() != null
    }

我看到你正在使用url: jdbc:postgresql://localhost:5432/db. 您实际上是在说“请针对我的本地数据库运行”:)

对于您的用例，我建议在 Testcontainers 中使用基于 JDBC 的容器。它将自动启动容器并在您关闭与它的最后一个连接时将其销毁。
