无法运行带有JPA的Spring引导测试运行器，没有HSQL

Question

我们正在尝试编写一个应用程序的测试用例，该应用程序使用AbstractRoutingDataSource，Mockito在Spring引导中同时使用MyBatis和JPA;我们能够嘲笑mybatis代码。当我们集成JPA时，@SpringBootTest尝试访问它失败的AbstractRoutingDataSource数据源。

@RunWith(SpringRunner.class) 
@SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT, classes = MyWebService.class) 
@ComponentScan(basePackages = { "com.me.xyz" }) 
@EnableAutoConfiguration 
public class MyWebServiceTest extends Mockito { 


} 

我们喜欢使用到的Mockito充分扩展，所以我们不希望使用HSQL/H2数据库我们的测试增加我们的代码中插入所需的所有数据。请在下面找到错误日志，

Answer 1

这可能是一些使用的，看看题为secion “测试应用切片”

https://spring.io/blog/2016/04/15/testing-improvements-in-spring-boot-1-4

您可以将您的代码？ Spring引导测试切片的想法是模拟出整个层次，例如，如果您只希望MVC层不打扰MyBatis/HIbernate层，就像这样（参见下文）。

如果你不使用切片注释，Spring Boot会尝试实例化它看起来不需要的实体管理器等。

@RunWith(SpringRunner.class) 
@WebMvcTest(UserVehicleController.class) 
public class UserVehicleControllerTests { 

@Autowired 
private MockMvc mvc; 

@MockBean 
private UserVehicleService userVehicleService; 

Answer 2

我有类似的问题。找到答案在下面的文章：

http://www.devthoughts.pl/2016/08/02/datajpatest-from-spring-boot/

春天开机默认通过与HSQL更换您的数据源。

使用与所需的弹簧引导和JPA测试的那些组合注释@AutoConfigureTestDatabase，解决我的问题：

@RunWith(SpringRunner.class) 
@DataJpaTest 
@AutoConfigureTestDatabase(replace = Replace.NONE) 

希望这有助于。
