Java 无法使用PowerMock模拟httpClient.execute方法

我使用EasyMock和PowerMock来模拟外部WS调用。我可以模拟getHttpClient方法，它是一个私有方法并返回CloseableHttpClient，但是我无法模拟httpClient.execute（httpPost）调用。我得到的httpResponse为空，而我期望的是200个http状态码

public class MyWsClient {

public void post(String data) throws Exception {

    CloseableHttpResponse httpResponse = null;
    String url = "http://abc:8080/myapp/mysvc"
    ...
    ....

    try {
        CloseableHttpClient httpClient = getHttpClient();

         HttpPost httpPost = new HttpPost(url);
        //populate the headers
        ....
        //set entity logic goes heres
        ....
        ......
        httpResponse = httpClient.execute(httpPost);


    } catch (Exception e) {
        //exception handling
    }   
  }
}

测试用例：

@Test
public void testPostWs() {
    try {
        // Given            
        CloseableHttpClient mockHttpClient = EasyMock.createMock(CloseableHttpClient.class);
        CloseableHttpResponse mockResponse = EasyMock.createMock(CloseableHttpResponse.class);
        MyWsClient classUnderTest = PowerMock.createPartialMock(MyWsClient.class, "getHttpClient");

        EasyMock.expect(mockResponse.getStatusLine()).andReturn(new BasicStatusLine(HttpVersion.HTTP_1_1, HttpStatus.SC_CREATED, "CREATED!"));


        PowerMock.expectPrivate(classUnderTest, "getHttpClient").andReturn(mockHttpClient);

        EasyMock.expect(mockHttpClient.execute(EasyMock.anyObject(HttpPost.class))).andReturn(mockResponse);
        PowerMock.replayAll(classUnderTest);
        //when
        classUnderTest.post(data);
    }  catch (Exception e) {
        e.printStackTrace();
        Assert.fail();
    }
}

您需要在最后执行

Easymock.replay（mockHttpClient，mockResponse）

，以便mocking激活。

成功了。非常感谢你帮我解决这个问题。
