Junit for RESTTemplate Clients

Question

我正在尝试为一个使用RestTemplate的REST Web服务客户端编写Junit。

以下是 REST 模板的方法调用：

final ResponseEntity<LogDateVO[]> result = restTemplate.postForEntity(url, LogDateInputVO, LogDateVO[].class);

在我的测试课程中，我正在尝试以下内容：

mockServer.expect(requestTo("http://abc.def.pvt:80/testOperations/api/traffic/logs/")).andExpect(method(HttpMethod.POST))
    .andRespond(MockRestResponseCreators.withSuccess("{ \"id\" : \"42\", \"name\" : \"Holiday Inn\"}", MediaType.APPLICATION_JSON));

我无法得到结果而无法继续这种方法，我需要一些帮助才能得到这个。

我的意图是当我的restTemplate被调用时，它应检查上述预期并返回一些数据的成功。

假设测试中的类有一个使用RestTemplate调用postForEntity的方法。有关详情，请查看this

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.web.client.RestTemplate;

@Service
public class SimpleRestService {
    @Autowired
    private RestTemplate restTemplate;

    public String getMessage() {
        String result;
        String httpResult = restTemplate.getForObject("http://google.com",
                String.class);
        result = "Message SUCCESS result: " + httpResult;

        return result;
    }
}

您的测试类应如下所示：

@ContextConfiguration(locations = {"classpath:aap.xml"})
public class SimpleRestServiceFunctionalTest extends AbstractJUnit4SpringContextTests {
    @Autowired
    private SimpleRestService simpleRestService;

    @Autowired
    private RestTemplate restTemplate;

    private MockRestServiceServer mockServer;

    @Before
    public void setUp() {
        mockServer = MockRestServiceServer.createServer(restTemplate);
    }

    @Test
    public void testGetMessage() {
        mockServer.expect(requestTo("http://google.com")).andExpect(method(HttpMethod.GET))
                .andRespond(withSuccess("resultSuccess", MediaType.TEXT_PLAIN));

        String result = simpleRestService.getMessage();

        mockServer.verify();
        assertThat(result, allOf(containsString("SUCCESS"), containsString("resultSuccess")));
    }

    @Test
    public void testGetMessage_500() {
        mockServer.expect(requestTo("http://google.com")).andExpect(method(HttpMethod.GET))
                .andRespond(withServerError());

        String result = simpleRestService.getMessage();

        mockServer.verify();
        assertThat(result, allOf(containsString("FAILED"), containsString("500")));
    }

    @Test
    public void testGetMessage_404() {
        mockServer.expect(requestTo("http://google.com")).andExpect(method(HttpMethod.GET))
                .andRespond(withStatus(HttpStatus.NOT_FOUND));

        String result = simpleRestService.getMessage();

        mockServer.verify();
        assertThat(result, allOf(containsString("FAILED"), containsString("404")));
    }
}
