使用jobLauncherTestUtils的Spring批处理集成测试

我的集成测试定义:

https://github.com/cristianprofile/spring-batch-testing/blob/master/src/test/java/test/BatchApplicationTests.java

@RunWith(SpringRunner.class)
@SpringBootTest

/* @Autowired
private JobLauncherTestUtils jobLauncherTestUtils;*/

public class BatchApplicationTests {

private static final String EXPECTED_FILE = "src/test/resources/users.csv";
private static final String OUTPUT_FILE = "src/main/resources//users.csv";
private static final String EXPECTED_FILE2 = "src/test/resources/users2.csv";
private static final String OUTPUT_FILE2 = "src/main/resources//users2.csv";

@Test
public void contextLoads()  throws Exception{
    System.out.println("Fake test ");
//      JobExecution jobExecution = jobLauncherTestUtils.launchJob();
//        JobExecution jobExecution = jobLauncherTestUtils.launchStep("step1");
//      Assert.assertEquals("COMPLETED",    jobExecution.getExitStatus().getExitCode());
//
//
//       AssertFile.assertFileEquals(new FileSystemResource(EXPECTED_FILE),
//                new FileSystemResource(OUTPUT_FILE));
//
//        AssertFile.assertFileEquals(new FileSystemResource(EXPECTED_FILE2),
//                new FileSystemResource(OUTPUT_FILE2));

}
