How to access Spring context in jUnit tests annotated with @RunWith and @ContextConfiguration?

Question

I have following test class

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"/services-test-config.xml"})
public class MySericeTest {

  @Autowired
  MyService service;
...

}

Is it possible to access services-test-config.xml programmatically in one of such methods? Like:

ApplicationContext ctx = somehowGetContext();

Answer 1

Since the tests will be instantiated like a Spring bean too, you just need to implement the ApplicationContextAware interface:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"/services-test-config.xml"})
public class MySericeTest implements ApplicationContextAware
{

  @Autowired
  MyService service;
...
    @Override
    public void setApplicationContext(ApplicationContext context)
            throws BeansException
    {
        // Do something with the context here
    }
}

For non xml needs, you can also do this:

@RunWith(SpringJUnit4ClassRunner.class)
/* must provide some "root" for the app-context, use unit-test file name to the context is empty */
@ContextConfiguration(classes = MyUnitTestClass.class)
public class MyUnitTestClass implements ApplicationContextAware {
