java - UnsatisfiedDependencyException Swagger2 + Sringboot + @RestClientTest

Question

我是 Swager 2 的新手，我一直在尝试进行一些测试，但没有成功，我希望我可以使用它。情况是这样的:

我正在使用 spring-boot 创建不同的休息服务，一切正常，但是当我尝试为我的服务创建单元测试时，会发生错误，并且是由 Swager 引起的。

如果我删除 @EnableSwagger2 注释，则测试有效。

@EnableSwagger2
@SpringBootApplication
public class ServerApplication extends WebMvcConfigurerAdapter
    {

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


@Override
public void addInterceptors(InterceptorRegistry registry)
{
    registry.addInterceptor(new LoggingInterceptor()).addPathPatterns("/**");
}


@Bean
public Docket docket()
{
    return new Docket(DocumentationType.SWAGGER_2)
        .select()
        .apis(RequestHandlerSelectors.basePackage(getClass().getPackage().getName()))
        .paths(PathSelectors.any())
        .build()
        .apiInfo(generateApiInfo());
}

   }

Unit test

@RunWith(SpringRunner.class)
@RestClientTest(DriverController.class)
public class DriverControllerTest
{

    @Autowired
    DriverController driverController;

    @Test
    public void getVehicleDetailsWhenResultIsSuccessShouldReturnDetails()
        throws Exception
    {

错误(抛出异常)

Answer 1

可能不是最好的解决方案，但我通过提供错误所提示的 bean 的模拟版本来运行测试。

即，

@MockBean
DocumentationPluginsBootstrapper mock; //keep swagger happy

@MockBean
WebMvcRequestHandlerProvider another;  //keep swagger happy
