如何在Spring Batch中测试单个步骤而不运行其他步骤？

    @Autowired

    @Autowired
    private StepBuilderFactory stepBuilderFactory;

    @Bean
    public Step step1() {
        return stepBuilderFactory.get("step1")
                .tasklet((contribution, chunkContext) -> {

                })
                .build();
    }

    @Bean

        return stepBuilderFactory.get("step2")
                .tasklet((contribution, chunkContext) -> {

                })
                .build();
    }

    @Bean
    public Job testJob() {
        return jobBuilderFactory.get("testJob")
                .start(step1())
                .next(step2())
                .build();
    }

    @Bean

        return new JobLauncherTestUtils();
    }
}

@SpringBootTest
public class BatchTest {

    @Autowired
    private JobLauncherTestUtils jobLauncherTestUtils;

    @Test
    public void testStep1() throws Exception {
        JobExecution jobExecution = jobLauncherTestUtils.launchStep("step1");
        // 检查步骤1的执行结果
    }
}
