PowerMockito whenNew gibt null zurück

Question

In der Quellklasse, die ich nicht umgestalten kann (so kann ich nicht Advices here verwenden) gibt es Objektkreationen mit = new XXX. Und ich muss ihre Funktionsaufrufe vortäuschen X(). Call().

Zu diesem Zweck benutze ich PowerMerchs whenNew() -Funktion. Aber ich habe null in der Klasse, die ich teste, die in diesem Fall LoginSuccessHandler ist. Hier meine LoginSuccessHandlerTest Klasse:

@RunWith(PowerMockRunner.class) 
public class LoginSuccessHandlerTest { 

    @InjectMocks private LoginSuccessHandler loginSuccessHandler; 
    @Mock private GuiSessionDAO guiSessionDAO; 
    @Mock private UserAuthorityDAO userAuthorityDAO; 
    @Mock private OrcaAuthorizationServiceBean orcaAuthorizationServiceBean; 
    @Mock private OrcaAuthorizationServiceBeanService orcaAuthorizationServiceBeanService; 
    @Mock private GetUserRolesReturnModel userRolesReturnModel; 

    private Authentication authentication; 
    private MockHttpServletRequest request; 
    private MockHttpServletResponse response; 

    @Before 
    public void setUp() { 
     request = new MockHttpServletRequest(); 
     response = new MockHttpServletResponse(); 
     authentication = new TestingAuthenticationToken("foo", "foo", "foo"); 
    } 

    @PrepareForTest({LoginSuccessHandler.class}) 
    @Test 
    public void onAuthenticationSuccess() throws Exception { 



     whenNew(OrcaAuthorizationServiceBeanService.class).withArguments(URL.class).thenReturn(orcaAuthorizationServiceBeanService); 

     p("Mocking Orca WS calls"); 
     when(orcaAuthorizationServiceBeanService.getOrcaAuthorizationServiceBeanPort()).thenReturn(orcaAuthorizationServiceBean); 
     when(orcaAuthorizationServiceBean.getUserRoles(any(Header.class), anyString())).thenReturn(userRolesReturnModel); 
     when(userRolesReturnModel.getUserRoles()).thenReturn(Collections.singletonList("ADMIN")); 

     p("Starting mock log in"); 
     loginSuccessHandler.onAuthenticationSuccess(request, response, authentication); 

     assertEquals(MockHttpServletResponse.SC_OK, response.getStatus()); 
    } 

    private void p(String s) { 
     System.out.println(s); 
    } 

Und hier i null erhalten

OrcaAuthorizationServiceBeanService service = new OrcaAuthorizationServiceBeanService(new URL(url)); 

Wenn ich debuggen ich, dass powermockito bestätigen kann, läuft diese Objekterstellung zu verspotten und diese Methode aufgerufen wird:

public static synchronized NewInvocationControl<?> putNewInstanceControl(Class<?> type, NewInvocationControl<?> control) { 
     return newSubstitutions.put(type, control); 
    } 

Und das sind die Parameter:

type = {Class@1755} "class com.ttech.timsgui.ldap.OrcaAuthorizationServiceBeanService" 
cachedConstructor = null 
newInstanceCallerCache = null 
name = "com.ttech.timsgui.ldap.OrcaAuthorizationServiceBeanService" 
classLoader = {MockClassLoader@2118} 
reflectionData = {SoftReference@2119} 
classRedefinedCount = 0 
genericInfo = null 
enumConstants = null 
enumConstantDirectory = null 
annotationData = null 
annotationType = null 
classValueMap = null 
control = {MockitoNewInvocationControl@2093} 
substitute = {InvocationSubstitute$$EnhancerByMockitoWithCGLIB$$4d9f6379@2109} "invocationSubstitute" 
    CGLIB$BOUND = true 
    CGLIB$CALLBACK_0 = {PowerMockMethodInterceptorFilter@2115} 
    CGLIB$CALLBACK_1 = {SerializableNoOp@2116} 

Und hier ist das Ergebnis, wenn es den Getter hits:

public static synchronized NewInvocationControl<?> getNewInstanceControl(Class<?> type) { 
    return newSubstitutions.get(type); 
} 

type = {Class@277} "class java.net.URL" 
newSubstitutions = {HashMap@1823} size = 1 
0 = {HashMap$Node@2195} "class com.ttech.timsgui.ldap.OrcaAuthorizationServiceBeanService" -> 
    key = {Class@1755} "class com.ttech.timsgui.ldap.OrcaAuthorizationServiceBeanService" 
    value = {MockitoNewInvocationControl@2137} 

diese null zurück und Objekterstellung kehrt zu null. Was verursacht dieses Problem?

Versuchen,

whenNew(OrcaAuthorizationServiceBeanService.class).withAnyArguments().thenReturn(orcaAuthorizationServiceBeanService);
