Spring Batch Java Config JobLauncherTestUtils

Question

I am currently working on a spring boot project that uses spring batch. I am trying to use JavaConfig instead of xml but it's difficult with all of the docs currently in xml.

I followed https://blog.codecentric.de/en/2013/06/spring-batch-2-2-javaconfig-part-5-modular-configurations but am having difficulties using the JobLauncherTestUtils. I know I need to tell the test to use the correct spring context, but I can't seem to figure out how to do it. I get the following error:

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.batch.test.JobLauncherTestUtils' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

My test looks like the following:

@RunWith(SpringRunner.class)
@SpringBootTest(classes = {MyApplication.class, MyJobConfiguration.class})
public class RetrieveDividendsTest {

    @Autowired
    private JobLauncherTestUtils jobLauncherTestUtils;

    @Test
    public void testSomething() throws Exception {
        jobLauncherTestUtils.launchJob();
    }

}

I stumbled upon the same issue and had a look at this XML configuration from the Spring Batch samples. Based on that I managed to get it working with:

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes = { BatchTest.BatchTestConfig.class })
public class BatchTest {

    @Autowired
    private JobLauncherTestUtils jobLauncherTestUtils;

    @Test
    public void demo() throws Exception {
        JobExecution jobExecution = jobLauncherTestUtils.launchJob();

        Assert.assertEquals(BatchStatus.COMPLETED, jobExecution.getStatus());
    }

    @Configuration
    @EnableBatchProcessing
    static class BatchTestConfig {

        @Bean
        JobLauncherTestUtils jobLauncherTestUtils() {
            return new JobLauncherTestUtils();
        }

        // rest omitted for brevity
    }
}

The test succeeds and my ItemWriter logs the processed elements as expected.

For spring Batch 4.1.x or above Version We can use @SpringBatchTest annotation that will automatically inject jobLauncherTestUtils , check sample example for more details Here

This is how you can created if u cant upgrade to 4.1.x or above

@Bean
     public JobLauncherTestUtils getJobLauncherTestUtils(){

            return new JobLauncherTestUtils() {
                @Override
                @Autowired
                public void setJob(@Qualifier("myjobname") Job job) {
                    super.setJob(job);
                }
            };
        }
