Why does the Spring Autowire stops working when I add the "RunWith" annotation?

Question

Once I add the RunWith annotation, that is @RunWith(PowerMockRunner.class) the Spring Autowire does not work anymore!

class B {  
  @Autowire  
  SessionFactory session;
}

@RunWith(PowerMockRunner.class)  
@PrepareForTest{SomeClass.class}

class Testing {  

  @Test
  methodA(){  
    //mehod 
  }

  @Test
  methodD(){  
  }    
}  

Now, method A makes a call to class B, but due to RunWith(PowerMockRunner) annotation, the Autowiring is not working. Any help would be greatly appreciated!

Answer 1

In 2016 you can use runner delegate with PowerMockito, effectively using two runners:

@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)

Answer 2

Spring is not magic (even if it seems like it sometimes). No where in your code are you giving spring a chance to start up an application context and do its work of auto wiring your beans. You need to either start the context yourself or switch your test to use @RunWith(SpringJUnit4ClassRunner.class). Unfortunately JUnit only supports a single runner at a time so you'll need to stop using the PowerMockRunner then.
