Solution for Spring 3.2 or newer

Spring starting with version 3.2 provides support for session/request scoped beans for integration testing.

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = TestConfig.class)
@WebAppConfiguration
public class SampleTest {

    @Autowired WebApplicationContext wac;

    @Autowired MockHttpServletRequest request;

    @Autowired MockHttpSession session;    

    @Autowired MySessionBean mySessionBean;

    @Autowired MyRequestBean myRequestBean;

    @Test
    public void requestScope() throws Exception {
        assertThat(myRequestBean)
           .isSameAs(request.getAttribute("myRequestBean"));
        assertThat(myRequestBean)
           .isSameAs(wac.getBean("myRequestBean", MyRequestBean.class));
    }

    @Test
    public void sessionScope() throws Exception {
        assertThat(mySessionBean)
           .isSameAs(session.getAttribute("mySessionBean"));
        assertThat(mySessionBean)
           .isSameAs(wac.getBean("mySessionBean", MySessionBean.class));
    }
}

Solution for Spring before 3.2 with listener

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = TestConfig.class)
@TestExecutionListeners({WebContextTestExecutionListener.class,
        DependencyInjectionTestExecutionListener.class,
        DirtiesContextTestExecutionListener.class})
public class SampleTest {
    ...
}

WebContextTestExecutionListener.java

public  class WebContextTestExecutionListener extends AbstractTestExecutionListener {
    @Override
    public void prepareTestInstance(TestContext testContext) {
        if (testContext.getApplicationContext() instanceof GenericApplicationContext) {
            GenericApplicationContext context = (GenericApplicationContext) testContext.getApplicationContext();
            ConfigurableListableBeanFactory beanFactory = context.getBeanFactory();
            beanFactory.registerScope(WebApplicationContext.SCOPE_REQUEST,
                    new SimpleThreadScope());
            beanFactory.registerScope(WebApplicationContext.SCOPE_SESSION,
                    new SimpleThreadScope());
        }
    }

Solution for Spring before 3.2 with custom scopes

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = TestConfig.class, locations = "test-config.xml")
public class SampleTest {

...

}

TestConfig.java

@Configuration
@ComponentScan(...)
public class TestConfig {

    @Bean
    public CustomScopeConfigurer customScopeConfigurer(){
        CustomScopeConfigurer scopeConfigurer = new CustomScopeConfigurer();

        HashMap<String, Object> scopes = new HashMap<String, Object>();
        scopes.put(WebApplicationContext.SCOPE_REQUEST,
                new SimpleThreadScope());
        scopes.put(WebApplicationContext.SCOPE_SESSION,
                new SimpleThreadScope());
        scopeConfigurer.setScopes(scopes);

        return scopeConfigurer

}

or with xml configuration

test-config.xml

<bean class="org.springframework.beans.factory.config.CustomScopeConfigurer">
    <property name="scopes">
        <map>
            <entry key="request">
                <bean class="org.springframework.context.support.SimpleThreadScope"/>
            </entry>
        </map>
        <map>
            <entry key="session">
                <bean class="org.springframework.context.support.SimpleThreadScope"/>
            </entry>
        </map>
    </property>
</bean>
