使用嵌入式内存 postgresql 数据库进行 Java Spring 启动单元测试

如何解决使用嵌入式内存 postgresql 数据库进行 Java Spring 启动单元测试

我有一个 Java Spring 启动项目，大量使用数据库 (Postgres) 作为它的存储库/数据。它是基本的 MVC 项目，控制器都是 REST 控制器。项目运行良好（服务已启动，能够通过 REST 客户端调用服务等）。

现在，我正在向其中添加单元测试。我对 Spring boot 很陌生，主要是单元测试部分。由于 CI/CD（构建管道），我无法使用持久/外部数据库进行测试。因此我需要使用内存数据库。

初始运行（主类）在项目启动时运行一堆数据库查询以建立缓存。所以我需要 postgres DB 进行测试（使用了很多 DB 函数）。

我正在经历 https://github.com/opentable/otj-pg-embedded，这似乎是一个不错的候选人。

我正在尝试编写如下的基本测试，但它失败了。

@ExtendWith(SpringExtension.class)
@FlywayTest
@DataJpaTest
@ActiveProfiles("test")
@AutoConfigureEmbeddedDatabase
public class AuthControllerTest {

    @Autowired
    private AuthController authController;

    @Test
    void contextLoads() {

    }

    @Test
    public void authenticateUsertest() {
    ...
    }
}

我的测试文件夹如下：

test
    |
    resources
            |
            application-test.properties
            db
              |
              migration
                     |
                     V1__baseline.sql
                     V2__static_data.sql
                     V3__changeset.sql

在 application-test.properties 文件中，我有以下属性：

spring.jpa.generate-ddl=true
spring.jpa.hibernate.ddl-auto=create
spring.jpa.database=POSTGREsql
spring.flyway.schemas=test
spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=true

但是，当我运行 Docker 测试失败时？为什么会搜索和使用docker？
