Wie kann der automatische Konfigurationsbericht von Spring in Tests aktiviert werden?

Question

Ich habe gerade herausgefunden, dass Spring einen Debug-Modus hat, der Einblicke in die Autokonfiguration gibt. Für einen Server kann er aktiviert werden, indem --debug als Anwendungsparameter übergeben wird.

Gibt es eine Möglichkeit, den Debug-Modus auch für Tests (mit der SpringJUnit4ClassRunner ausgeführt) zu aktivieren?

Wenn die Auto-Konfigurationsbericht arbeitet, sollte es eine Ausgabe wie folgt drucken:

--debug setzt debug Eigenschaft, die auf dem Auto-Konfigurationsbericht schaltet. Sie können das gleiche in Ihrem Test mit z. B. @TestPropertySource in Ihrer Testklasse tun:

@RunWith(SpringJUnit4ClassRunner.class) 
@SpringApplicationConfiguration(Application.class) 
@TestPropertySource(properties = "debug=true") 
public class YourTests { 
    // … 
}
