Class JobScopeTestExecutionListener

java.lang.Object
org.springframework.batch.test.JobScopeTestExecutionListener
All Implemented Interfaces:
org.springframework.test.context.TestExecutionListener
public class JobScopeTestExecutionListener extends Object implements org.springframework.test.context.TestExecutionListener
A TestExecutionListener that sets up job-scope context for dependency injection into unit tests. A JobContext will be created for the duration of a test method and made available to any dependencies that are injected. The default behaviour is just to create a JobExecution with fixed properties. Alternatively it can be provided by the test case as a factory methods returning the correct type. Example: 
 @ContextConfiguration
 @TestExecutionListeners({ DependencyInjectionTestExecutionListener.class, JobScopeTestExecutionListener.class })
 @RunWith(SpringJUnit4ClassRunner.class)
 public class JobScopeTestExecutionListenerIntegrationTests {

        // A job-scoped dependency configured in the ApplicationContext
        @Autowired
        private ItemReader<String> reader;

        public JobExecution getJobExecution() {
                JobExecution execution = MetaDataInstanceFactory.createJobExecution();
                execution.getExecutionContext().putString("foo", "bar");
                return execution;
        }

        @Test
        public void testJobScopedReader() {
                // Job context is active here so the reader can be used,
                // and the job execution context will contain foo=bar...
                assertNotNull(reader.read());
        }
