Question

使用Restlet我为我的Java应用程序创建了一个路由器。

从使用curl，我知道每个不同的GET，POST＆amp; DELETE请求适用于每个URI并返回正确的JSON响应。

我想为每个URI设置JUnit测试，以使测试过程更容易。但是，我不确定向每个URI发出请求以获取JSON响应的最佳方法，然后我可以进行比较以确保结果符合预期。有关如何做到这一点的任何想法？

Answer 1

您可以使用Restlet Client发出请求，然后检查每个响应及其表示。

例如：

Client client = new Client(Protocol.HTTP);
Request request = new Request(Method.GET, resourceRef);
Response response = client.handle(request);

assert response.getStatus().getCode() == 200;
assert response.isEntityAvailable();
assert response.getEntity().getMediaType().equals(MediaType.TEXT_HTML);

// Representation.getText() empties the InputStream, so we need to store the text in a variable
String text = response.getEntity().getText();
assert text.contains("search string");
assert text.contains("another search string");

我实际上并不熟悉JUnit，assert或一般的单元测试，所以如果我的例子中有些内容，我会道歉。希望它仍然可以说明一种可能的测试方法。

祝你好运！

单元测试ServerResource

// Code under test
public class MyServerResource extends ServerResource {
  @Get
  public String getResource() {
    // ......
  }
}

// Test code
@Autowired
private SpringBeanRouter router;
@Autowired
private MyServerResource myServerResource;

String resourceUri = "/project/1234";
Request request = new Request(Method.GET, resourceUri);
Response response = new Response(request);
router.handle(request, response);
assertEquals(200, response.getStatus().getCode());
assertTrue(response.isEntityAvailable());
assertEquals(MediaType.TEXT_PLAIN, response.getEntity().getMediaType());
String responseString = response.getEntityAsText();
assertNotNull(responseString);

我的测试类中router和资源是@Autowired。 Spring应用程序上下文中的相关声明看起来像

<bean name="router" class="org.restlet.ext.spring.SpringBeanRouter" />
<bean id="myApplication" class="com.example.MyApplication">
  <property name="root" ref="router" />
</bean> 
<bean name="/project/{project_id}" 
      class="com.example.MyServerResource" scope="prototype" autowire="byName" />

myApplication与

类似

public class MyApplication extends Application {
}

我在REST junit测试用例中获得了挑战响应设置的答案

@Test
public void test() {
    String url ="http://localhost:8190/project/user/status";
    Client client = new Client(Protocol.HTTP);
    ChallengeResponse challengeResponse = new ChallengeResponse(ChallengeScheme.HTTP_BASIC,"user", "f399b0a660f684b2c5a6b4c054f22d89");
    Request request = new Request(Method.GET, url);
    request.setChallengeResponse(challengeResponse);
    Response response = client.handle(request);
    System.out.println("request"+response.getStatus().getCode());
    System.out.println("request test::"+response.getEntityAsText());
}

基于answer of Avi Flax我将此代码重写为java并使用junitparams运行它，这是一个允许传递参数化测试的库。代码如下：

@RunWith(JUnitParamsRunner.class)
public class RestServicesAreUpTest {

    @Test
    @Parameters({
        "http://url:port/path/api/rest/1, 200, true",
        "http://url:port/path/api/rest/2, 200, true", })
    public void restServicesAreUp(String uri, int responseCode,
        boolean responseAvaliable) {
    Client client = new Client(Protocol.HTTP);
    Request request = new Request(Method.GET, uri);
    Response response = client.handle(request);

    assertEquals(responseCode, response.getStatus().getCode());
    assertEquals(responseAvaliable, response.isEntityAvailable());
    assertEquals(MediaType.APPLICATION_JSON, response.getEntity()
        .getMediaType());

    }
}
