I'm writing unit tests now. I need to simulate long-run method with Mockito to test my implementation's timeout handling. Is it possible with Mockito?

Something like this:

when(mockedService.doSomething(a, b)).thenReturn(c).after(5000L);

You could simply put the thread to sleep for the desired time. Watch out tho - such things can really slow down your automated test execution, so you might want to isolate such tests in a separate suite

It would look similar to this: 

when(mock.load("a")).thenAnswer(new Answer<String>() {
   @Override
   public String answer(InvocationOnMock invocation){
     Thread.sleep(5000);
     return "ABCD1234";
   }
});
