Komponententest für Ein- und Ausschalten der Funktion

Question

Wir verwenden Togglz, um die Funktionen in unserem Projekt ein- und auszuschalten. Die folgende TogglzFeature Enum setzt org.togglz.core.Feature Schnittstelle

public enum TogglzFeature implements Feature { 

    @EnabledByDefault 
    @Label("Current XSLT code") 
    FEATURE_XSLT, 

    @Label("NEW JAXB code") 
    FEATURE_JAXB; 

    public boolean isActive() { 
     FeatureManager manager = FeatureContext.getFeatureManager(); 
     return manager.isActive(this); 
    } 

} 

dann eine der Methoden im Test (zB mut_1(params)) prüft das Enum, so etwas wie

if(TogglzFeature.FEATURE_JAXB.isActive()) { dothings();} 

Beachten Sie, dass Merkmal togglz ist nicht in den Params von mut_1. Das mut_1 hebt es nur in der Laufzeit aus dem Kontext auf.

Also was ist der beste Weg, um die mut_1() wissen lassen, dass ich will TogglzFeature.FEATURE_JAXB.isActive() zurück True?

Ich habe versucht, dies mit Mockito/PowerMock

@RunWith(PowerMockRunner.class) 
@PrepareForTest({TogglzFeature.class}) 
public class myTestClass { 

    //private members and set up 

    @Test 
    public void testTogglz(){ 
     PowerMockito.mockStatic(TogglzFeature.class); 
     BDDMockito.given(TogglzFeature.FEATURE_JAXB.isActive()).willReturn(true); 

     //execution and verification 
    } 
} 

Und das System spuckt diese alle auf mich

Answer 1

Sie brauchen nichts zu spotten. Togglz wird mit einem speziellen Modul zum Testen von Funktionsmerkmalen geliefert. Werfen Sie einen Blick hier:

http://www.togglz.org/documentation/testing.html

Es gibt zum Beispiel eine JUnit Regel, die eine einfache Möglichkeit bietet Funktionen wechseln:

public class SomeJunitTest { 

    @Rule 
    public TogglzRule togglzRule = TogglzRule.allEnabled(MyFeatures.class); 

    @Test 
    public void testToggleFeature() { 

    // all features are active by default 
    assertTrue(MyFeatures.FEATURE_ONE.isActive()); 

    // you can easily modify the feature state using the TogglzRule 
    togglzRule.disable(MyFeatures.FEATURE_ONE); 
    assertFalse(MyFeatures.FEATURE_ONE.isActive()); 

    } 

}
