Question

我正在通过使用testng进行春季批处理工作来编写集成测试用例。在我的应用程序中，我使用Google API作为地址，并使用Mail Sender发送电子邮件。在我的集成测试用例中，在测试运行期间需要一段时间才能进行连接，最后发送异常看上去很丑陋且耗时。

我尝试模拟bean，但是我不知道如何在集成测试用例中精确地完成操作。

Google Api Code:

@Slf4j
public final class GoogleApiContext {

    private static GeoApiContext context;

    private GoogleApiContext() {
    }

    public static GeoApiContext getGeoApiContext(String apiKey, int maxQps) {

        if (context == null) {
            log.info("Creating google api context having key - {} and maxQps - {}", apiKey, maxQps);
            context = new GeoApiContext.Builder().apiKey(apiKey).queryRateLimit(maxQps).build();
        }

        return context;
    }

}

Mail Sender Code:

@Override
    public Boolean sendMailWithAttachment(final MailBo mailBo, final String pathToAttachment, final String fileName) {
        try {
            log.info("Sending Email {}", mailBo);
            MimeMessage message = mailSender.createMimeMessage();
            MimeMessageHelper helper = new MimeMessageHelper(message, true);
            helper.setTo(mailBo.getTo());
            helper.setSubject(mailBo.getSubject());
            helper.setText(mailBo.getText());
            File file = new File(pathToAttachment);
            helper.addAttachment(fileName, file);
            mailSender.send(message);
            log.info("Mail sent successfully");
            return true;

        } catch (MessagingException e) {
            log.info("Mail Exception {}", e);
            return false;
        }
    }

Integration Test Case:

@SpringBootTest(
    classes = {ApplicationLauncher.class, BatchConfiguration.class, BatchTestConfig.class})
public class PostalJobTest extends AbstractTestNGSpringContextTests {

  @Autowired
  private JobLauncherTestUtils jobLauncherTestUtils;

  @Autowired
  JobLauncher dataloadJobLauncher;

  @Autowired
  private Job postalJob;

  @Test
  public void testPostalJob_valid_response() throws Exception {
    String fileName = getFileName(FileLocation.POSTAL_VALID, FileLocation.TEMP_POSTAL_VALID);
    JobParametersBuilder jobParametersBuilder = getJobParametersBuilder(fileName);
    jobLauncherTestUtils.setJob(postalJob);
    jobLauncherTestUtils.setJobLauncher(dataloadJobLauncher);
    JobExecution jobExecution =
        jobLauncherTestUtils.launchJob(jobParametersBuilder.toJobParameters());
    Assert.assertEquals(jobExecution.getStatus(), BatchStatus.STARTING);
    Thread.sleep(2000);
    while (jobExecution.isRunning()) {
    }
    Assert.assertEquals(jobExecution.getStatus(), BatchStatus.COMPLETED);


  }

我想模拟GeoApiContext和MailSender进行集成测试用例，如果我可以创建一个虚拟服务器来实现响应，以便测试运行更快而没有任何异常。

在集成测试用例中，没有直接方法可以模拟bean。因此，另一种解决方案是在应用程序中进行setter注入，并在测试用例中更改该bean。

  // mail service
  private JavaMailSender mailSender;

  @Autowired
  public void setMailSender(JavaMailSender mailSender) {
    this.mailSender = mailSender;
  }


  // test file

  @Autowired
  private MailServiceImpl mailService;

  @BeforeClass
  public void setJob() {
    jobLauncherTestUtils.setJob(postalJob);
    mailService.setMailSender(new JavaMailSenderTestImpl());
  }

需要在集成测试用例中模拟bean
