问题

尝试使用以下测试代码来测试我的客户端：

private static final HttpPost EXPECTED_POST = new HttpPost(someURI);

@Test
public void sendingPostRequest() throws IOException {
    classUnderTest.takeParamsAndSend(REQUEST_STRING);
    verify(client).execute(EXPECTED_POST);
    verifyNoMoreInteractions(client);
}

在生产代码中，大致是这样的：

URI uri = createURI();
HttpPost post = new HttpPost(uri);
return client.execute(post);

结果是在相同的execute方法上出现了“Comparison Failure”，而且在实际输出中，有一行空行。大致如下所示：

期望输出：

"client.execute(
    POST somePostRequest HTTP/1.1
);"

实际输出：

"client.execute(
   POST somePostRequest HTTP/1.1
);
"

Tried to test my client with this following test:

    private static final HttpPost EXPECTED_POST = new HttpPost(someURI);
    
        @Test
        public void sendingPostRequest() throws IOException {
            classUnderTest.takeParamsAndSend(REQUEST_STRING);
            verify(client).execute(EXPECTED_POST);
            verifyNoMoreInteractions(client);
        }

And in the production code it&#39;s something like this:

    URI uri = createURI();
    HttpPost post = new HttpPost(uri);
    return client.execute(post);

The result is a &quot;Comparison Failure&quot; on the same execute and on the actual, there is an empty row.
Looks something like this:
expected:

    &quot;client.execute(
        POST somePostRequest HTTP/1.1
    );&quot;

actual:

    &quot;client.execute(
       POST somePostRequest HTTP/1.1
    );
    &quot;

edit: 如评论中所述，大多数 Apache HTTP 客户端 API 类并没有覆盖 `java.lang.Object＃equals` 方法，因此您不能可靠地使用 `org.mockito.ArgumentMatchers＃eq(T)` 方法。
您应该使用 `org.mockito.ArgumentMatchers＃argThat` 匹配器，在谓词中定义您的相等条件。

以下是我如何测试它：

```java
import static org.mockito.ArgumentMatchers.argThat;

//...
@Test
void stackOverflow64222693() {

    // Given
    HttpClient client = mock(HttpClient.class);
    URI uri = URI.create("https://stackoverflow.com/questions/64222693");
    HttpPost post = new HttpPost(uri);

    // When
    client.execute(post);

    // Then
    URI expectedUri = URI.create("https://stackoverflow.com/questions/64222693");
    HttpPost expectedPost = new HttpPost(expectedUri);

    verify(client).execute(argThat(argument -> argument.getURI().equals(expectedPost.getURI()) &&
                                                argument.getMethod().equals(expectedPost.getMethod()) &&
                                                Arrays.equals(argument.getAllHeaders(), expectedPost.getAllHeaders()) &&
                                                argument.getProtocolVersion().equals(expectedPost.getProtocolVersion())));
}

import static org.mockito.ArgumentMatchers.argThat;

//...
@Test
  void stackOverflow64222693() {

    // Given
    HttpClient client = mock(HttpClient.class);
    URI        uri    = URI.create("https://stackoverflow.com/questions/64222693");
    HttpPost   post   = new HttpPost(uri);

    // When
    client.execute(post);

    // Then
    URI      expectedUri  = URI.create("https://stackoverflow.com/questions/64222693");
    HttpPost expectedPost = new HttpPost(expectedUri);

    verify(client).execute(argThat(argument -> argument.getURI().equals(expectedPost.getURI()) &&
                                               argument.getMethod().equals(expectedPost.getMethod()) &&
                                               Arrays.equals(argument.getAllHeaders(), expectedPost.getAllHeaders()) &&
                                               argument.getProtocolVersion().equals(expectedPost.getProtocolVersion())));
  }
