"Application context not configured for this file"

Let me straight, I’m sick and tired of this Application context not configured for this file warning. I don’t know what it wants from me. I create a context bound to that config file in my test class. If it wants me to write any configuration xmls, I won’t do that

// the warning happens here
public class Config {
// here's where I use that config
@ContextConfiguration(classes = Config.class)
public class AppTest {
    private Sage sage;
    public void testApp() {

Could you please tell me how I can avoid that warning?
