Unit testing batch jobs

Spring Batch provides different ways to test a batch job; the whole job, only one step, or just a Tasklet class can be tested.

How to do it…

Follow these steps to unit test batch jobs:

1. Add the Maven dependency for spring-batch-test in pom.xml:

   <dependency>
     <groupId>org.springframework.batch</groupId>
     <artifactId>spring-batch-test</artifactId>
     <version>3.0.2.RELEASE</version>
   </dependency>

2. In the unit test class, if using JUnit, load the Spring Batch configuration class like this:

   @RunWith(SpringJUnit4ClassRunner.class)
   @ContextConfiguration(classes = {BatchConfig.class})
   public class BatchJob1Test {
   ...

3. If using TestNG, load the Spring Batch configuration class as follows:

   @ContextConfiguration(classes = {BatchConfig.class}) public ...
