使用 Mockito 模拟 post 请求引发 javax.ws.rs.ProcessingException: RESTEASY004655: 无法调用请求
Mocking a post request using Mockito raises javax.ws.rs.ProcessingException: RESTEASY004655: Unable to invoke request
我是 Mockito 的新手，我需要模拟一个 post 请求，以便我可以单独测试客户端。但是，无论我做什么，我都会得到 RESTEASY004655: Unable to invoke request 异常。这是我目前所拥有的简化版本。我有 class TestClassA，它向 api 发送 post 请求，如下所示：
import java.io.IOException;
import java.util.HashMap;
import java.util.Map;
import java.util.concurrent.TimeUnit;
import javax.ws.rs.client.Entity;
import javax.ws.rs.core.Response;
import org.jboss.resteasy.client.jaxrs.ResteasyClient;
import org.jboss.resteasy.client.jaxrs.ResteasyClientBuilder;
import org.jboss.resteasy.client.jaxrs.ResteasyWebTarget;
import com.fasterxml.jackson.databind.ObjectMapper;
public class TestClassA {
public int moveActual(String path) throws IOException {
Response resp = null;
String newHome = "0" ;
ResteasyClient client = new ResteasyClientBuilder().build();
ResteasyWebTarget callTarget = client.target(path) ;
Map<String, Object> request = new HashMap<>();
request.put("operation", "dislocation");
request.put("direction", "right");
request.put("amount", "2");
request.put("unit", "metric");
String payload = new ObjectMapper().writeValueAsString(request);
resp = callTarget.request().post(Entity.entity(payload, "application/json"));
String outcome = resp.readEntity(String.class);
ObjectMapper outcomeMapper = new ObjectMapper();
@SuppressWarnings("unchecked")
Map<String, Object> finalResponse = (Map<String, Object>) outcomeMapper.readValue(outcome, Map.class);
if (finalResponse != null) {
newHome = (String) finalResponse.get("coordinate");
}
return Integer.parseInt(newHome) ;
}
}
我尝试使用下面的 mockito 测试模拟 post 请求：
import static org.junit.Assert.assertEquals;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.Answers;
import org.mockito.ArgumentMatchers;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.junit.MockitoJUnitRunner;
import static org.mockito.BDDMockito.given;
import java.util.HashMap;
import java.util.Map;
import org.jboss.resteasy.client.jaxrs.ResteasyWebTarget;
import javax.ws.rs.client.Entity;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import javax.ws.rs.core.Response.Status;
import externalTests.TestClassA;
@RunWith(MockitoJUnitRunner.class)
public class DispositionMockTest {
@Mock(answer = Answers.RETURNS_DEEP_STUBS)
ResteasyWebTarget targetMock;
@InjectMocks
TestClassA classA;
@Test
public void dispositionTest() throws Exception {
// Given
Map<String, Integer> outcomeMap = new HashMap<String, Integer>() ;
outcomeMap.put("coordinate", 4) ;
Response resp = Response.status(Status.OK).type(MediaType.APPLICATION_JSON).entity(outcomeMap).build() ;
// Builder req = DispositionMockTest.fakeRequest() ;
// given(req.post(ArgumentMatchers.any(Entity.class))).willReturn(fakeRequest()) ;
given(targetMock.request().post(ArgumentMatchers.any(Entity.class))).willReturn(resp) ;
// When
int result = classA.moveActual("url to what has to run") ;
// Then
assertEquals(4, result);
}
}
我还尝试在测试中使用两条注释掉的行来模拟请求方法，并从下面的方法中得到它 return 或多或少是伪造的 Builder。
public static Builder fakeRequest() {
ResteasyClient httpClient = new ResteasyClientBuilder().build();
ResteasyWebTarget target = httpClient.target("");
Builder req = target.request() ;
return req ;
}
但是我一直收到这个异常。

我尝试了很多我在网上找到的可能的解决方案，但我无法解决任何问题。如果有人知道我如何模拟 post 请求，我将非常感谢向他们学习。
因为你模拟了 ResteasyWebTarget 并且没有定义 request() 方法的 return 应该是什么，所以你得到了那个异常。
您应该首先模拟请求并将其 return 发送到 request() 方法，并将 post() 方法的行为定义为 mockedRequest
@Mock
private Invocation.Builder mockedRequest;
@Test
public void dispositionTest() throws Exception {
when(targetMock.request()).thenReturn(mockedRequest);
when(mockedRequest.post(any(Entity.class))).thenReturn(resp) ;
}
对于可能需要它的人。我找不到使用 mockito 完成它的方法。我不得不转移到wiremock。在 wiremock 中，您只需记录一个成功的事务，创建一个 wiremock 服务器对象，然后让它模拟记录的行为。更容易和更快。
