Application context is coming as null while running spring integration test with @ContextConfiguration

I am trying to write integration test with spring. Below is the test class

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath*:**/context*.xml"})
public class MyFirstTestClass {

  @AutoWired
  private ApplicationContext applicationContext;

  @Test
  public void testApplicationContext {
    applicationContext.getName();
  }

}

When i run the test from maven i am getting null pointer exception because applicationContext is null.Iam not able to understand the reason.Also in logs also i dont see any error.I tried putting configuration in one of the application context files. Still iam getting same error.

When i use classpath*:**/context*.xml to create context manually it works. But i believe when i use context configuraton its not loading the application context file.I am not getting any error as well. Kindly suggest
