Class StepScopeTestExecutionListener

  • All Implemented Interfaces:
    org.springframework.test.context.TestExecutionListener
    public class StepScopeTestExecutionListener
extends java.lang.Object
implements org.springframework.test.context.TestExecutionListener
    A TestExecutionListener that sets up step-scope context for dependency injection into unit tests. A StepContext 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 StepExecution 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, StepScopeTestExecutionListener.class })
 @RunWith(SpringJUnit4ClassRunner.class)
 public class StepScopeTestExecutionListenerIntegrationTests {
 
        // A step-scoped dependency configured in the ApplicationContext
        @Autowired
        private ItemReader<String> reader;
 
  public StepExecution getStepExecution() {
    StepExecution execution = MetaDataInstanceFactory.createStepExecution();
    execution.getExecutionContext().putString("foo", "bar");
    return execution;
  }
 
        @Test
        public void testStepScopedReader() {
                // Step context is active here so the reader can be used,
      // and the step execution context will contain foo=bar...
                assertNotNull(reader.read());
        }
 
 }
