Java 模仿HttpClient的execte()方法
我想模拟Java 模仿HttpClient的execte()方法,java,unit-testing,powermockito,java-http-client,Java,Unit Testing,Powermockito,Java Http Client,我想模拟executeHttpClass的method来返回一个虚拟响应,但是我的测试代码正在实际执行请求 类别代码- class MyService { private CloseableHttpClient newHttpClient() { try { SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory( new SSL
execute
HttpClass的method来返回一个虚拟响应,但是我的测试代码正在实际执行请求
类别代码-
class MyService {
private CloseableHttpClient newHttpClient() {
try {
SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
new SSLContextBuilder().loadTrustMaterial(TrustAllStrategy.INSTANCE).build(),
NoopHostnameVerifier.INSTANCE);
return HttpClients.custom().setSSLSocketFactory(sslsf).build();
} catch (KeyManagementException | NoSuchAlgorithmException | KeyStoreException exception) {
logger.error(exception);
}
return null;
}
public String create(CreateRequestDTO Request) {
CloseableHttpClient client = newHttpClient();
CloseableHttpResponse response = null;
HttpPut httpPut = new HttpPut("MyUrl...");
try {
response = client.execute(httpPut);
} catch (IOException exception) {
return "exception";
}
return response.toString();
}
}
测试类别代码-
@PrepareForTest({ MyService.class })
@PowerMockIgnore({ "com.sun.org.apache.xerces.*", "javax.xml.*", "org.xml.*", "org.w3c.*", "com.sun.org.apache.xalan.*",
"javax.activation.*", "javax.management.*", "javax.net.ssl.*", "javax.crypto.*" })
@RunWith(PowerMockRunner.class)
public class MyServiceTest {
@InjectMocks
private MyService MyService;
@Mock
private CloseableHttpClient closeableHttpClient;
@Mock
private HttpClient httpClient;
@Mock
private CloseableHttpResponse closeableHttpResponse;
@Mock
private HttpPut httpPut;
@Mock
private HttpEntity httpEntity;
@Before
public void setupTest() {
MockitoAnnotations.initMocks(this);
}
@Test
public void testCreate() throws Exception {
// MyService MyServiceSpy = PowerMockito.spy(MyService);
MyService MyServiceSpy = PowerMockito.spy(MyService);
CreateRequestDTO createRequestDTO = new CreateRequestDTO();
createRequestDTO.setLocation("room 1");
createRequestDTO.setStartTime("3 pm");
createRequestDTO.setEndTime("4 pm");
try {
PowerMockito.doReturn(closeableHttpClient).when(MyServiceSpy, "newHttpClient");
// PowerMockito.when(MyServiceSpy,
// "newHttpClient").thenReturn(httpClient);
// PowerMockito.verifyPrivate(MyServiceSpy).invoke("newHttpClient");
String jsonEntity = " created successfully";
HttpEntity httpEntity = EntityBuilder.create().setText(jsonEntity)
.setContentType(org.apache.http.entity.ContentType.APPLICATION_JSON).build();
closeableHttpResponse.setEntity(httpEntity);
PowerMockito.doReturn(closeableHttpResponse).when(closeableHttpClient).execute(any(HttpPut.class));
// PowerMockito.doReturn(closeableHttpResponse).when(httpClient).execute(any(HttpPut.class));
String res = MyService.create(createRequestDTO);
logger.info("Result from create : " + res);
Assert.assertTrue(res.substring(0, 5).matches("BEGIN"));
} catch (Exception e) {
e.printStackTrace();
throw e;
}
}
}
我尝试了Mockito而不是PowerMockito,但请求仍然是真实执行的。您的问题不是模拟客户端,而是构建它。
当前,当您使用HttpClients.custom()
static方法时,您的代码将构建一个新的客户端而不是模拟客户端
由于需要模拟静态方法,因此需要PowerMockito.mockStatic()
首先,您需要将HttpClients
添加到@PrepareForTest
注释中,然后您应该执行以下操作:
PowerMockito.mockStatic(HttpClients.class);
when(HttpClients.custom()).thenReturn(mockedBuilder);
when(mockedBuilder.setSSLSocketFactory(any(SSLSocketFactory.class)).theReturn(mockedBuilder);
when(mockedBuilder.build()).thenReturn(httpClient);// your mock object
可能的副本。如前所述(在原始线程中),需要重构服务代码,以便可以利用模拟。在其当前形式中,行为如预期的那样。这是必需的MyService MyServiceSpy=PowerMockito.spy(MyService);1.我使用私有方法的模拟返回模拟的http客户端,这不对吗?2.在您建议的解决方案中,什么是mockedBuilder?我尝试使用@Mock private HttpClientBuilder mockedBuilder模拟Http客户端生成器代码>但获取错误org.mockito.exceptions.misusing.InvalidUseOfMatchersException:在此处检测到错误放置或误用的参数匹配器:
在线when(mockedBuilder.setsslssocketfactory(any(SSLSocketFactory.class))。然后返回(mockedBuilder);
