我有一个Sping Boot 类的单元测试，当我运行测试时，它将一个文件发送到带有POST请求的URL，它将实际请求发送到真实的的URL。我认为ClosebleHttpClient没有被嘲笑。

class FileSenderTest {
    @InjectMocks
    FileSender fileSender;
    
    @Mock
    UrlConfig urlConfig;
    
    @Mock
    InetAddress inetAddress;

    @Mock
    SSLContextFactory sslContextFactory = new SSLContextFactory();

    @BeforeEach
    void setUp() {
    }

    @AfterEach
    void tearDown() {
    }
   
    @Test
    public void postData() throws Exception {
        URL url = new URL("/someUrl");
        urlConfig.setURL(url);
        urlConfig.setPassword("somePassword123");
        fileSender = new FileSender(urlConfig);

        URL res = getClass().getClassLoader().getResource("test.json");
        File file = Paths.get(res.toURI()).toFile();
        String filePath = file.getAbsolutePath();
        
        HttpPost httpPost = mock(HttpPost.class);
        StatusLine statusLine = mock(StatusLine.class);
        CloseableHttpClient closeableHttpClient = mock(CloseableHttpClient.class);
        CloseableHttpResponse closeableHttpResponse = mock(CloseableHttpResponse.class);

        when(statusLine.getStatusCode()).thenReturn(200);
        when(closeableHttpResponse.getStatusLine()).thenReturn(statusLine);
        when(closeable.HttpClient.execute(httpPost)).thenReturn(closeableHttpResponse);

        int response = fileSender.sendFile(filePath);

        Assertions.assertEquals(200, response);
    }

}

下面是要测试的类：

@Service 
public class FileSender {
    private final UrlConfig urlConfig;
    SSLContext sslContext;
    
    @Autowired
    public FileSender(UrlConfig urlConfig) {
        this.urlConfig = urlConfig;
    }

    public int sendFile(String targetFileName) throws IOException {
        Path tracesPath = Paths.get(targetFileName);
        HttpPost httpPost = new HttpPost(this.UrlConfig.getURL().toString());
        httpPost.addHeader("Accept", "application/json");

        MultipartEntityBuilder builder = MultipartEntityBuilder.create();        
        builder.addBinary("file", new ByteArrayInputStream(Files.readAllBytes(tracesPath)), ContentType.APPLICATION_OCTET_STREAM, targetFileName);

        HttpEntity multipart = builder.build();
        httpPost.setEntity(multipart);
        
        sslContext = this.UrlConfig.getSSLContext();
        sslContext = SSLContextFactory.create().this.urlConfig.setSSLContext(sslContext);

       try (CloseableHttpClient httpClient = HttpClients.custom()setSSLContext(sslContext).build);
           CloseableHttpResponse response = httpClient.execute(httpPost)) {
               return response.getStatusLine().getStatusCode();
        }  catch (IOException e) {
               log.error(e);
        }
        return 500;
    }
}

有没有办法只重构测试来解决这个问题。
