Spring 如何测试具有外部客户端的my rest控制器？

我有一个使用2个fein客户端的rest控制器，我想用不同的示例编写和测试rest控制器，我不是编写springboot测试的专家

在这个场景中，我没有要测试的存储库，只是通过rest控制器访问假客户机。下面是我的测试控制器代码

@RestController
public class CustomerController {

    @Autowired
    private CustomerClient customerClient;

    @Autowired
    private PaymentsClient paymentsClient;

    @RequestMapping(path = "/getAllCustomers", method = RequestMethod.GET)
    public ResponseEntity<Object> getAllCustomers() {
        List<Customer> customers = customerClient.getAllCustomers();
        return new ResponseEntity<>(customers, HttpStatus.OK);

    }

    @RequestMapping(path = "/{customerId}", method = RequestMethod.GET)
    public ResponseEntity<Object> get(@PathVariable() long customerId) {
        try {
            Customer c = customerClient.getCustomerById(customerId);
            if (c != null) {
                return new ResponseEntity<>(c, HttpStatus.OK);
            } else {
                return ResponseEntity.status(HttpStatus.NOT_FOUND).body("Customer Not Found");
            }
        } catch (Exception e) {
            e.printStackTrace();
            return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).body(e.getMessage());
        }
    }

    @RequestMapping(path = "/{customerId}", method = RequestMethod.PATCH)
    public ResponseEntity<Object> UpdateCustomer(@PathVariable() Long customerId, @RequestBody Customer customer) {
        Customer c;
        try {
            c = customerClient.update(customerId, customer);
            if (c != null) {
                return new ResponseEntity<>(c, HttpStatus.OK);
            } else {
                return ResponseEntity.status(HttpStatus.NOT_FOUND).body("Customer Not Found");
            }
        } catch (Exception e) {
            e.printStackTrace();
            return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).body(e.getMessage());
        }
    }

    @RequestMapping(path = "", method = RequestMethod.POST)
    public ResponseEntity<Object> saveCustomer(@RequestBody Customer customer) {
        Customer c;
        try {
            c = customerClient.saveCustomer(customer);
            return new ResponseEntity<>(c, HttpStatus.OK);
        } catch (Exception e) {
            e.printStackTrace();
            return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).body(e.getMessage());
        }
    }

    @RequestMapping(path = "/registerPayment", method = RequestMethod.POST)
    public ResponseEntity<Object> saveCustomer(@RequestBody Payment payment) {
        Payment p = null;
        Customer c = null;
        try {
            c = customerClient.getCustomerById(payment.getCustomerId());
            p = paymentsClient.saveCustomer(payment);
            return new ResponseEntity<>(p, HttpStatus.OK);
        } catch (Exception e) {
            if (null == c) {
                return ResponseEntity.status(HttpStatus.UNPROCESSABLE_ENTITY).body("Customer Does not Exist");
            } else {
                e.printStackTrace();
                return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).body(e.getMessage());
            }
        }
    }

我得到下面的错误

NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.test.web.servlet.MockMvc' available: expected at least 1 bean which qualifies as autowire candidate.

它和编写任何其他JUnit测试一样简单

@RunWith(SpringRunner.class)
@SpringBootTest
@ActiveProfiles("test")
public class CustomerControllerTest {

    @Mock
    private CustomerClient customerClient;

    @InjectMocks
    private CustomerController customerController;

    @Test
    public void getAllCustomers() {
        List<Customer> customers = new ArrayList<>();
        customers.add(new Customers("name"));
        Mockito.when(customerClient.getAllCustomers()).thenReturn(customers);
        Mockito.assertEquals(customers.toString(),customerController.getAllCustomers())
    }

}

您需要自己的可在MockMvc之外工作的外部客户端：

导入静态java.nio.charset.StandardCharsets.UTF_8； 导入静态java.util.function.function.identity； 导入静态org.springframework.test.web.servlet.request.MockMvcRequestBuilders.request； 进口国外客户； 进口外国请求； 进口国外反应； 导入java.io.UncheckedIOException； 导入java.io.UnsupportedEncodingException； 导入java.net.URI； 导入java.net.url解码器； 导入java.util.ArrayList； 导入java.util.List； 导入java.util.stream.collector； 导入org.springframework.http.HttpHeaders； 导入org.springframework.http.HttpMethod； 导入org.springframework.mock.web.MockHttpServletResponse； 导入org.springframework.test.web.servlet.MockMvc； 导入org.springframework.test.web.servlet.ResultActions； 导入org.springframework.test.web.servlet.request.MockHttpServletRequestBuilder； 公共类MockMvcFeignClient实现客户端{ 私有最终MockMvc MockMvc； 公共MockMvcFeignClientMockMvc mockMvc{ this.mockMvc=mockMvc； } @凌驾 公共响应executeRequest请求，请求.选项{ URI requestUrl=URI.createrequest.url； List uriVars=新阵列列表； 字符串urlTemplate=FillVarsandGetUrlTemplaterRequestUrl，uriVars； HttpMethod=HttpMethod.valueOfrequest.method； 字节[]body=request.body； HttpHeaders HttpHeaders=convertHeadersrequest； MockHttpServletRequestBuilder requestBuilder=requestmethod，urlTemplate，uriVars.toArray .校长 .内容体； mockhttpservletresp； 试一试{ ResultActions ResultActions=mockMvc.performrequestBuilder； resp=resultActions.andReturn .getResponse； }捕获异常e{ 在执行请求时抛出新的IllegalStateExceptionError，e； } 返回ConverterResponseRequest，resp； } 静态字符串fillVarsAndGetUrlTemplateURI请求URL，列表Urivar{ StringBuilder urlTemplate=新建StringBuilderrequestUrl.getPath； 如果requestUrl.getQuery！=null{ urlTemplate.append'？'； String[]pairs=requestUrl.getRawQuery.split&； 对于int i=0；iheaders.putheader，新的ArrayListvalues； 返回标题； } 专用静态响应convertResponseRequest请求，MockHttpServletResponse响应{ 返回响应.builder .请求 .statusresp.getStatus .bodyresp.getContentAsByteArray .HeaderResp.getHeaderNames.stream .collectCollectors.toMapidentity，resp:：getHeaders 建筑 } } 并使用它创建您的外国客户：

返回外国建筑商 .clientnew MockMvcFeignClientmockMvc ...

因此，对于可以进行MockMvc集成测试的测试，现在您可以通过假客户端调用它。

我认为您需要另外添加@AutoConfigureMockMvc来配置MockMvc。原始问题使用MockMvc，而不是直接调用控制器！

@RunWith(SpringRunner.class)
@SpringBootTest
@ActiveProfiles("test")
public class CustomerControllerTest {

    @Mock
    private CustomerClient customerClient;

    @InjectMocks
    private CustomerController customerController;

    @Test
    public void getAllCustomers() {
        List<Customer> customers = new ArrayList<>();
        customers.add(new Customers("name"));
        Mockito.when(customerClient.getAllCustomers()).thenReturn(customers);
        Mockito.assertEquals(customers.toString(),customerController.getAllCustomers())
    }

}
