在 Spock 上调用服务得到空对象

Calling a service on Spock gets null object

我正在尝试在具有以下结构的 spock 框架下执行测试

class UserServiceSpec extends Specification{

   ModelMapper modelMapper = Stub(ModelMapper.class)

   UserRepository userRepository=Mock(UserRepository.class)

   UserService userService

   def setup(){
       userService= new UserServiceImpl(userRepository,modelMapper)
   }
   def "find user by email"(){
      given: "Creates a constant with an existing email"
          def constant ="juan@rodriguez.com"
      when: "Calling the method findUserByEmail"
          def response= userService.findUserByEmail(constant)
      then:"Comparing the response result with the constant"
        
         response.getEmail()==constant
   }
}

然而,当我尝试获取 response.getEmail() 的值时,结果是一个空对象,它应该获取与“常量”相同的参数,错误是:

Cannot invoke method getEmail() on null object

UserService 的代码结构和实现是:

 public interface UserService {

     UserModel findUserByEmail(String email);
 }

UserService 实现是:

@Service
@Qualifier("userDetailsService")
public class UserServiceImpl implements UserService, UserDetailsService {

    private final UserRepository userRepository;

    private final ModelMapper modelMapper;

    public UserServiceImpl(UserRepository userRepository,ModelMapper modelMapper){
       this.userRepository= userRepository;
       this.modelMapper= modelMapper;
    }

}

但是,如果我使用相同的方法从控制器(spring 项目)调用服务,我会得到一个带有它的参数的对象。如何修复此 spock 测试?

您没有指定与模拟 UserRepository 的任何交互,因此 Spock returns null 来自您对其进行的任何方法调用。假设您的存储库是普通存储库,请这样说:

then:
userRepository.findByEmail(constant) >> { c -> new UserEntity(email: c, ...) }
constant == response.email // expected value comes first, and you can use Groovy property syntax
