i am trying to get my Junit Testcase working. The actual batch is ok. But in future i want to tdd my apps. So i started with junit und spring-batch and came up with the following code. but i am running in an error.
Here is my @EnableBatchConfiguration Class from under test.
package de.securess.batch.mail.config;
import org.springframework.batch.core.Job;
import org.springframework.batch.core.Step;
import org.springframework.batch.core.configuration.annotation.JobBuilderFactory;
import org.springframework.batch.core.configuration.annotation.StepBuilderFactory;
import org.springframework.batch.repeat.RepeatStatus;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class BatchMailAppConfig {
@Autowired
private JobBuilderFactory jobs;
@Autowired
private StepBuilderFactory steps;
@Bean
public Step step0() {
Step step = steps.get("step0")
.tasklet((contribution, chunkContext) -> {
System.out.println("JB: Step0 with chunkContex");
return RepeatStatus.FINISHED;
})
.build();
return step;
}
@Bean Job job() {
System.out.println("JB: job started ...");
Job job = jobs.get("job")
.start(step0())
.build();
return job;
}
}
And here is my test class:
package de.securess.batch.mail;
import static org.junit.Assert.assertEquals;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.batch.core.ExitStatus;
import org.springframework.batch.core.JobExecution;
import org.springframework.batch.test.JobLauncherTestUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.context.annotation.Bean;
import org.springframework.test.context.ContextConfiguration;
@SpringBootTest
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {de.securess.batch.mail.SpringBatchMailApplication.class,de.securess.batch.mail.config.BatchMailAppConfig.class})
public class SpringBatchMailApplicationTests {
@Autowired
private JobLauncherTestUtils jobLauncherTestUtils;
@Bean
public JobLauncherTestUtils jobLauncherTestUtils() {
return new JobLauncherTestUtils();
}
@Test
public void test() throws Exception {
JobExecution jobExecution = this.jobLauncherTestUtils.launchJob();
assertEquals(ExitStatus.COMPLETED, jobExecution.getExitStatus());
}
}
And here comes the error code:

The JobLauncherTestUtils
is not provided by default in the test execution context. You need to create it and declare it as a bean in your test context. Here is an example: https://github.com/spring-projects/spring-batch/blob/master/spring-batch-test/src/test/java/org/springframework/batch/test/StepScopeAnnotatedListenerIntegrationTests.java#L98-L101
In the upcoming version 4.1, we added a new annotation @SpringBatchTest
that adds it to the test context. You can find more details about it here: https://docs.spring.io/spring-batch/4.1.x/reference/html/testing.html#creatingUnitTestClass . It is already available in version 4.1.0.M2
For Spring-batch below version 4.1.x . this is how we can manually create JobLauncherTestUtils
@Bean
public JobLauncherTestUtils getJobLauncherTestUtils(){
return new JobLauncherTestUtils() {
@Override
@Autowired
public void setJob(@Qualifier("myjobname") Job job) {
super.setJob(job);
}
};
}
