Question

我是Spring Batch的新手，我有一个以下主程序，我希望使用jobLauncherTestUtils将其转换为测试用例。我们怎么做到这一点？

我跟着http://docs.spring.io/spring-batch/reference/html/testing.html，但我没有看到任何指针。请指导。

private void run() {
        String[] springConfig = { "spring/batch/jobs/job-extract-users.xml" };
        ApplicationContext context = new ClassPathXmlApplicationContext(springConfig);

        JobLauncher jobLauncher = (JobLauncher) context.getBean("jobLauncher");
        Job job = (Job) context.getBean("testActualJob");

        try {
            JobParameters param = new JobParametersBuilder().addString("age", "20").toJobParameters();

            JobExecution execution = jobLauncher.run(job, param);
            System.out.println("----------------------------------------------");
            System.out.println("Exit Status : " + execution.getStatus());
            System.out.println("Exit Status : " + execution.getAllFailureExceptions());
            System.out.println("-----------------------------------------------");
        } catch (Exception e) {
            e.printStackTrace();
        }

        System.out.println("Done !!");
    }

Answer 1

引自documentation： -

startupJob发放方法由JobLauncherTestUtils类提供。 utils类还提供了 launchJob（JobParameters），其中允许测试给出特定的参数。

您的代码如下所示： -

JobParameters param = new JobParametersBuilder().addString("age", "20").toJobParameters();
 JobExecution jobExecution = jobLauncherTestUtils.launchJob(param).getStatus();

Answer 2

如果您只想运行具有作业参数的特定step，可以执行以下操作：

JobParameters param = new JobParametersBuilder()
    .addString("language", "en_US")
    .toJobParameters();

JobExecution jobExecution = jobLauncherTestUtils.launchStep("stepName", param);

Answer 3

我在这里找到解决方案：http://docs.spring.io/spring-batch/apidocs/org/springframework/batch/test/JobLauncherTestUtils.html

@Test
    public void testMysqlToXMLWithParameters() throws Exception {
        JobParameters jobParameters = new JobParametersBuilder().addString("age", "20").toJobParameters();
        JobExecution jobExecution = jobLauncherTestUtils.launchJob(jobParameters);
        Assert.assertEquals(jobExecution.getStatus(), BatchStatus.COMPLETED);
    }

完成！

仅发布Junit的另一种方法-

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:request-jobs/spring-batch-config-jobs.xml"})
public class TestMyJob {

   @Autowired
    private JobLauncher jobLauncher;

    @Autowired
    @Qualifier(value = "myJobName")
    private Job myJob;

    @Test
    public void testJob() throws Exception {
        JobParametersBuilder builder = new JobParametersBuilder()
                .addLong("timestamp", System.currentTimeMillis());

        JobExecution jobExecution = jobLauncher.run(myJob, builder.toJobParameters());
        Assert.assertEquals("COMPLETED", jobExecution.getExitStatus().getExitCode());
    }

}

如何将JobParameters传递给Spring Batch Junit测试用例JobLauncherTestUtils？
