Question

我正在寻找如何在单个构造函数中注入bean和mock的方法。

@Service
public class SomeService {

private EndpointUrlProvider endpointUrlProvider;
private RestTemplate restTemplate;

@Autowired
public SomeService(EndpointUrlProvider endpointUrlProvider, RestTemplate restTemplate){
  this.endpointUrlProvider = endpointUrlProvider;
  this.restTemplate = restTemplate;
}

测试：

class SomeTest extends Specification {

@Autowired
EndpointUrlProvider endpointUrlProvider

RestTemplate restTemplate = Mock {
    postForEntity(_, _, SomeResponse.class) >> new ResponseEntity(new SomeResponse(), HttpStatus.OK)
 }

SomeService someService = new SomeService(endpointUrlProvider, restTemplate)

//some tests
    }

当我触发测试时，someService中的endpointUrlProvider为null。我做错了什么？测试这个的最佳方法是什么？

据我所知，你正试图做部分嘲笑。要注入Spring bean，首先需要TestContextManager。因此，请使用SpringRunner或SpringJUnit4ClassRunner运行测试。这应该做的工作：

@RunWith(SpringRunner.class)
public class SomeServiceTest {

    @Autowired
    private EndpointUrlProvider endpointUrlProvider;

    @Before
    public setUp() {
        RestTemplate restTemplate = mock(RestTemplate.class);
        SomeService someService = new SomeService(endpointUrlProvider, restTemplate);
    }
}

Spock Spring通过构造函数注入模拟和bean
