（原创）Junit中遇到FTP的上传下载该如何Mock

在测试过程中，遇到代码中存在static，final，new对象，ftp需要被mock时，一向很令人头疼，本篇文章，简单介绍一下，ftp的上传下载等方法应该如何mock。

我和我的同事lsj同时对该方法进行测试，采用了两种不同的方案，在下面会依次展示，以及过程中遇到的坑和解决方法。

实例

待测试代码举例，待测method为sendEmailAffix()：

@Override 
public Response<BaseDTO> sendEmailAffix(Request<SendEmailRequestDTO> request) {
   BaseDTO baseDTO;
   SendEmailRequestDTO sendDTO = request.getRequestData();
  
   String langType = getLanguageType(sendDTO.getEntId());
   //获取邮件模板
   MessageEmailTemplate messageEmailTemplate = new MessageEmailTemplate();
   messageEmailTemplate.setTemplateType(ServiceConstants.MsgEmailTemplate.*TEMPLATE_TYPE_EMAIL*);
   messageEmailTemplate.setFuncId(ServiceConstants.MsgEmailTemplate.*NEGOTIATION_SUC_CLOUD_SIGN_EMAIL*);
   messageEmailTemplate.setLanguageType(langType);
   MessageEmailTemplate emailTemplate = messageEmailTemplateMapper.queryTemplateContentById(messageEmailTemplate);
   if (null == emailTemplate) {
       baseDTO = new BaseDTO();
       baseDTO.setStatus(false);
       baseDTO.setMsg("mail template empty!");
       *[log](http://log.info/)*[.info](http://log.info/)("templateID-33 mail template empty!");
       return ResponseFactory.*getResponse*(baseDTO, request);
   }
   //替换模板占位符
   String finalContent = emailTemplate.getTemplateContent(); sendDTO.setEmailPerson(emailTemplate.getSender());
   sendDTO.setEmailTitle(emailTemplate.getTitle());
   sendDTO.setEmailMsg(finalContent);
   sendDTO.setAppendix(ServiceConstants.MsgEmailTemplate.*TEMPLATE_LANGUAGE_TYPE_CN*.equals(langType) ?
   "洽谈备忘录.png" : "Negotiation Memo.png");

   //授权发送邮件
   BaseDTO resp = this.accreditSendEmail(sendDTO);
   return ResponseFactory.*getResponse*(resp, request); 
}

public BaseDTO accreditSendEmail(SendEmailRequestDTO sendEmailReq) {
 BaseDTO baseDTO = new BaseDTO();
 baseDTO.setStatus(false);
 //下载本地FTP服务器的附件图片，上传到远端的FTP上
 InputStream inputStream;
 try {
 inputStream = downloadPicFromLocalFTP(sendEmailReq);
 } catch (IOException e) {
 log.error("从gms FTP服务器下载文件失败！{}", e.getMessage());
 baseDTO.setStatus(false);
 baseDTO.setMsg("there is no picture on ftp");
 return baseDTO;
 }
​
 //获得affixId
 String sequence = messageEmailTemplateMapper.querySequence();//16位序列号
 String blankString = "            ";//12位空格
 String affixId = MessagePush.SYSTEM_ID + MessagePush.DISPTYPE_02 + sequence + blankString + ServiceConstants.EmailSendState.EMAIL_SEQUENCE;
​
 //上传签约图片到FTP2服务器
 try {
 uploadPic2RemoteFTP(inputStream, affixId);
 } catch (Exception e) {
 log.error("向邮件FTP服务器上传文件失败！{}", e.getMessage());
 baseDTO.setStatus(false);
 baseDTO.setMsg("upload to mcis's ftp fail");
 return baseDTO;
 }
​
 //发送邮件和附件
 SIPLauncherBean sipBean = sendEmailAccessory(sendEmailReq, affixId);
 if (null != sipBean && null != sipBean.getRespHeader() && "0000000".equals(sipBean.getRespHeader().getMsgcde())) {
 baseDTO.setStatus(true);
 log.info("sendEmailAndAccessory调用结束，返回信息={}", sipBean.getRespHeader().getMsgcde());
 }
​
 log.info("SendEmailServiceImpl   sendEmail end");
 return baseDTO;
 }
​
 //下载FTP1服务器的附件图片
 public InputStream downloadPicFromLocalFTP(SendEmailRequestDTO sendEmailReq) throws IOException {
 FtpEntity ftpEntityIn = new FtpEntity(ConfigUtils.getProperty("ftp.A.ip"),
 ConfigUtils.getProperty("ftp.A.username"),
 ConfigUtils.getProperty("ftp.A.password"),
 Integer.parseInt(ConfigUtils.getProperty("ftp.A.port")));
 InputStream inputStream = null;
 inputStream = new FTPUtil(ftpEntityIn).downloadToStream(
 ConfigUtils.getProperty("ftp.A.picture.address"), sendEmailReq.getPictureName());
 return inputStream;
 }
​
 //上传签约图片到FTP2服务器
 public Boolean uploadPic2RemoteFTP(InputStream inputStream, String affixId) throws IOException {
 FtpEntity ftpEntity = new FtpEntity(ConfigUtils.getProperty("ftp.B.ip"),
 ConfigUtils.getProperty("ftp.B.username"),
 ConfigUtils.getProperty("ftp.B.password"),
 Integer.parseInt(ConfigUtils.getProperty("ftp.B.port")),
 ConfigUtils.getProperty("ftp.B.picture.address"));
 new FTPUtil(ftpEntity).uploadFile(inputStream, affixId);//上传时不带文件后缀
 return true;//上传成功
 }

可观察到，代码中需要测试的method和FTP上传下载method在同一个类中。需要连接FTP服务器进行上传下载图片，而简单的@Mock无法实现对于FTP的模拟。下面提供两种UT测试方法。

添加POM

首先，添加所需的POM依赖，引入powermock

<dependency>
 <groupId>org.powermock</groupId>
 <artifactId>powermock-api-mockito</artifactId>
 <version>${powermock.version}</version>
 <scope>test</scope>
 <exclusions>
 <exclusion>
 <groupId>org.mockito</groupId>
 <artifactId>mockito-all</artifactId>
 </exclusion>
 <exclusion>
 <groupId>org.javassist</groupId>
 <artifactId>javassist</artifactId>
 </exclusion>
 </exclusions>
 </dependency>
 <dependency>
 <groupId>org.powermock</groupId>
 <artifactId>powermock-module-junit4</artifactId>
 <version>${powermock.junit.version}</version>
 <scope>test</scope>
 <exclusions>
 <exclusion>
 <groupId>org.mockito</groupId>
 <artifactId>mockito-all</artifactId>
 </exclusion>
 <exclusion>
 <groupId>junit</groupId>
 <artifactId>junit</artifactId>
 </exclusion>
 <exclusion>
 <groupId>org.javassist</groupId>
 <artifactId>javassist</artifactId>
 </exclusion>
 </exclusions>
 </dependency>
 <dependency>
 <groupId>org.javassist</groupId>
 <artifactId>javassist</artifactId>
 <version>3.20.0-GA</version>
 <scope>test</scope>
 </dependency>

PowerMockito准备

在你写的UT Class前先加@RunWith(PowerMockRunner.class)和@PrepareForTest

@RunWith(PowerMockRunner.class)
@PrepareForTest(SendEmailServiceImpl.class)
public class SendEmailAffixServiceUT extends UTContext {

   @InjectMocks
   private SendEmailServiceImpl sendEmailAffixService;

   @Mock
   private Launcher launcher;

   @Rule
   public TemporaryFolder temporaryFolder = new TemporaryFolder();

   @Mock
   MessageEmailTemplateMapper messageEmailTemplateMapper;

方法一

对new FtpEntity()和new FTPUtil()采用PowerMockito.whenNew()，进行mock

FtpEntity ftpEntityIn = new FtpEntity(ConfigUtils.getProperty("ftp.A.ip"),
 ConfigUtils.getProperty("ftp.A.username"),
 ConfigUtils.getProperty("ftp.A.password"),
 Integer.parseInt(ConfigUtils.getProperty("ftp.A.port")));

Junit代码如下

@Test
 public void test_sendEmailAffix_success() throws Exception{
 SendEmailRequestDTO sendDTO = new SendEmailRequestDTO();
 sendDTO.setEmail("GMS58@cs-boc.cn");
 sendDTO.setTransCode("0151fd79c6974f229d3001dc5889d6a8");
 sendDTO.setPictureName("cloud_sign_0151fd79c6974f229d3001dc5889d6a8.png");
​
 //获取邮件模板
 EntUserLoginInfo entUserLoginInfo = new EntUserLoginInfo();
 entUserLoginInfo.setLanguageType(ServiceConstants.UserLoginLanguageType.CN);
 when(entUserLoginInfoMapper.queryLanguageTypeByEntId(anyString())).thenReturn(entUserLoginInfo);
 MessageEmailTemplate messageEmailTemplateReq = new MessageEmailTemplate();
 messageEmailTemplateReq.setTemplateType(ServiceConstants.MsgEmailTemplate.TEMPLATE_TYPE_EMAIL);
 messageEmailTemplateReq.setFuncId(33);
 MessageEmailTemplate emailTemplateRet = new MessageEmailTemplate();
 emailTemplateRet.setSender("sender");
 emailTemplateRet.setTitle("title");
 emailTemplateRet.setTemplateContent("template content");
 when(messageEmailTemplateMapper.queryTemplateContentById(any(MessageEmailTemplate.class))).thenReturn(emailTemplateRet);
​
 //发送邮件接口
 SIPLauncherBean sipLauncherBean = new SIPLauncherBean();
 LauncherRespHeader respHeader = new LauncherRespHeader();
 respHeader.setMsgcde("0000000");
 sipLauncherBean.setRespHeader(respHeader);
​
 Response<SIPLauncherBean> sipResponse = ResponseFactory.getResponse(sipLauncherBean);
 when(launcher.launch(any(Request.class), any(Class.class))).thenReturn(sipResponse);
​
 FTPUtil mockFtpUtil = PowerMockito.mock(FTPUtil.class);
 PowerMockito.whenNew(FTPUtil.class).withArguments(any(FtpEntity.class)).thenReturn(mockFtpUtil);
 FtpEntity mockFtpEntity = PowerMockito.mock(FtpEntity.class);
 PowerMockito.whenNew(FtpEntity.class).withArguments(anyString(), anyString(), anyString(),anyInt()).thenReturn(mockFtpEntity);
​
 InputStream inputStream = PowerMockito.mock(InputStream.class);
 when(mockFtpUtil.downloadToStream(anyString(), anyString())).thenReturn(inputStream);
 when(mockFtpUtil.uploadFile(any(InputStream.class), anyString())).thenReturn(true);
​
 Response<BaseDTO> resp = sendEmailAffixService.sendEmailAffix(RequestFactory.createRequest(sendDTO));
 Assert.assertTrue(resp.getResponseData().isStatus());
 }

注意：原理通过mock构造函数得到新的对象，该对象的方法可以打桩，官网示例如下


image-20200916195418725.png

示例关键代码段：

FTPUtil mockFtpUtil = PowerMockito.mock(FTPUtil.class);
PowerMockito.whenNew(FTPUtil.class).withArguments(any(FtpEntity.class)).thenReturn(mockFtpUtil);
 FtpEntity mockFtpEntity = PowerMockito.mock(FtpEntity.class);
 PowerMockito.whenNew(FtpEntity.class).withArguments(anyString(), anyString(), anyString(),anyInt()).thenReturn(mockFtpEntity);
​
 InputStream inputStream = PowerMockito.mock(InputStream.class);
 when(mockFtpUtil.downloadToStream(anyString(), anyString())).thenReturn(inputStream);
 when(mockFtpUtil.uploadFile(any(InputStream.class), anyString())).thenReturn(true);

方法二

对FTP uploadFile和downloadToStream方法进行打桩，屏蔽调用方法

@Rule
 public TemporaryFolder temporaryFolder = new TemporaryFolder();
​
 @Test
 public void test_sendEmaiAffix_success_spy() throws Exception{
 SendEmailServiceImpl spy = PowerMockito.spy(sendEmailAffixService);
 SendEmailRequestDTO sendDTO = new SendEmailRequestDTO();
 sendDTO.setEmail("GMS58@cs-boc.cn");
 sendDTO.setTransCode("0151fd79c6974f229d3001dc5889d6a8");
 sendDTO.setPictureName("cloud_sign_0151fd79c6974f229d3001dc5889d6a8.png");
​
 //获取邮件模板
 EntUserLoginInfo entUserLoginInfo = new EntUserLoginInfo();
 entUserLoginInfo.setLanguageType(ServiceConstants.UserLoginLanguageType.CN);
 when(entUserLoginInfoMapper.queryLanguageTypeByEntId(any(String.class))).thenReturn(entUserLoginInfo);
 MessageEmailTemplate messageEmailTemplateReq = new MessageEmailTemplate();
 messageEmailTemplateReq.setTemplateType(ServiceConstants.MsgEmailTemplate.TEMPLATE_TYPE_EMAIL);
 messageEmailTemplateReq.setFuncId(33);
 MessageEmailTemplate emailTemplateRet = new MessageEmailTemplate();
 emailTemplateRet.setSender("sender");
 emailTemplateRet.setTitle("title");
 emailTemplateRet.setTemplateContent("template content");
 when(messageEmailTemplateMapper.queryTemplateContentById(any(MessageEmailTemplate.class))).thenReturn(emailTemplateRet);
​
 //发送邮件接口
 SIPLauncherBean sipLauncherBean = new SIPLauncherBean();
 LauncherRespHeader respHeader = new LauncherRespHeader();
 respHeader.setMsgcde("0000000");
 sipLauncherBean.setRespHeader(respHeader);
​
 //下载上传接口
 File file = temporaryFolder.newFile("test.jpg");
 InputStream inputStream = new FileInputStream(file);
 PowerMockito.doReturn(inputStream).when(spy).downloadPicFromLocalFTP(any(SendEmailRequestDTO.class));
 PowerMockito.doReturn(true).when(spy).uploadPic2RemoteFTP(any(InputStream.class),any(String.class));

 Response<SIPLauncherBean> sipResponse = ResponseFactory.getResponse(sipLauncherBean);
 when(launcher.launch(any(Request.class), any(Class.class))).thenReturn(sipResponse);
​
 Response<BaseDTO> resp = spy.sendEmailAffix(RequestFactory.createRequest(sendDTO));
 Assert.assertTrue(resp.getResponseData().isStatus());
 }

原理，同一类内的方法进行打桩，需要@InjectMock该类，对这个生命的类变量进行spy，PowerMockito.spy(sendEmailAffixService)。然后，对spy的method进行打桩。

Process finished with exit code -1

原因

  1. 使用过旧的字节码生成工具进行类生成。

  2. 使用较旧的JDT编译应用。

解决方法

<dependency>
 <groupId>org.javassist</groupId>
 <artifactId>javassist</artifactId>
 <version>3.20.0-GA</version>
 <scope>test</scope>
 </dependency>

坑二，采用方法二时，尽管使用spy，依然调用了方法内部，并没有被屏蔽。

原因


image-20200916171737303.png

注意：

//Impossible: real method is called so spy.get(0) throws IndexOutOfBoundsException (the list is yet empty)

笔者尝试发现，当spy的方法是通过new对象引用的时候，使用when(spy.get(0)).thenReturn("foo");会进入到方法内部，而此种情况下doReturn("foo").when(spy).get(0);可以正确打桩。
