Following the official Spring batch unit testing guide to create a standard unit test case.
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {
"classpath:spring/batch/jobs/job-abc.xml",
"classpath:spring/batch/config/context.xml"})
public class AppTest {
@Autowired
private JobLauncherTestUtils jobLauncherTestUtils;
@Test
public void launchJob() throws Exception {
JobExecution jobExecution = jobLauncherTestUtils.launchJob();
assertEquals(BatchStatus.COMPLETED, jobExecution.getStatus());
}
}
P.S spring-batch-test.jar is added to the classpath.
Problem
When launches above unit test, it prompts JobLauncherTestUtils no such bean error message?
org.springframework.beans.factory.BeanCreationException: Could not autowire field:
private org.springframework.batch.test.JobLauncherTestUtils com.mkyong.AppTest.jobLauncherTestUtils;
......
org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type
[org.springframework.batch.test.JobLauncherTestUtils] found for dependency:
expected at least 1 bean which qualifies as autowire candidate for this dependency.
......

Solution
Adding spring-batch-test.jar into the classpath will not create the JobLauncherTestUtils bean automatically.
To fix it, declares a JobLauncherTestUtils bean in one of your Spring configuration file.
spring/batch/config/test-context.xml
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.2.xsd">
<bean class="org.springframework.batch.test.JobLauncherTestUtils"/>
</beans>
And loads it into the unit test.
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {
"classpath:spring/batch/jobs/job-abc.xml",
"classpath:spring/batch/config/context.xml",
"classpath:spring/batch/config/test-context.xml"})
public class AppTest {
@Autowired
private JobLauncherTestUtils jobLauncherTestUtils;
@Test
public void launchJob() throws Exception {
JobExecution jobExecution = jobLauncherTestUtils.launchJob();
assertEquals(BatchStatus.COMPLETED, jobExecution.getStatus());
}
}
Hi mkyong,
I am getting below error. Could you please advice if anything I messed. Thanks
Error:expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)
Hi All,
I am getting error : No qualifying bean of type . Please advice is highly appreciated. Thanks
[com.bns.mcac.config.DatabaseConfig] found for dependency [com.bns.mcac.config.DatabaseConfig]: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
If you would added how to set JobLauncherTestUtils also from a configuration class:
@Bean
public JobLauncherTestUtils jobLauncherTestUtils() {
return new JobLauncherTestUtils();
}
This article would be perfect. Anyway, like always your articles are state of the art. A really thank you for them 😉
hi Mkyong.. First of all thank you for posts as many posts saved mytime and cleared my doubts.
I have a question in Spring Junit (am a beginner).. while defining the bean class it says noclassdef found. This is because the test-configuration.xml is inside my test folder and all the bean classes are outside test folder. How do i resolve this?
hi … when i run this file, i am getting error i.e. nosuchbeandefinitionexception
