单元测试中的调用目标异常

如何解决单元测试中的调用目标异常

我是单元测试的新手。请让我了解错误发生在哪里。

FirebaeAuthRespository.java

    public mutablelivedata<IBDataWrapper<User>> signInWithEmailPassword(FirebaseAuth firebaseAuth,String email,String password){

    mutablelivedata<IBDataWrapper<User>> authenticatedUsermutablelivedata = new mutablelivedata<>();
    firebaseAuth.signInWithEmailAndPassword(email,password).addOnCompleteListener(new OnCompleteListener<AuthResult>() {
        @Override
        public void onComplete(@NonNull Task<AuthResult> task) {

            if(task.isSuccessful()){
                FirebaseUser firebaseUser = firebaseAuth.getCurrentUser();
                if (firebaseUser != null) {
                  

              authenticatedUsermutablelivedata.setValue(IBDataWrapper.success(firebaseUser,null));
                }
            }else{
                authenticatedUsermutablelivedata.setValue(IBDataWrapper.error(task.getException().getMessage(),null,null));
            }
        }
    });
   return authenticatedUsermutablelivedata;
}

视图模型

public class Loginviewmodel extends Androidviewmodel {

mutablelivedata<IBDataWrapper<User>> authenticatedUsermutablelivedata;
private IBFirebaseAuthRepository mIBFirebaseAuthRepository;

public mutablelivedata<IBDataWrapper<User>> ibAuthenticatedUserLiveData;
FirebaseAuth mFirebaseAuth;

public Loginviewmodel(Application application) {
    super(application);
    mIBFirebaseAuthRepository = new IBFirebaseAuthRepository();
}

public Loginviewmodel(Application application,FirebaseAuth firebaseAuth) {
    super(application);

    mFirebaseAuth = firebaseAuth;
    mIBFirebaseAuthRepository = new IBFirebaseAuthRepository();
}

public void authenticateUser(String email,String password){
   mFirebaseAuth = FirebaseAuth.getInstance();
    ibAuthenticatedUserLiveData = mIBFirebaseAuthRepository.signInWithEmailPassword(mFirebaseAuth,email,password);
}


}

                    }
                    else{
                        IBLogger.logErrorMessage("IntiBhojanam","[Error Occurred 1] - Retrieving User Profile");
                    }

                }
                else{
                    IBLogger.logErrorMessage("IntiBhojanam","[Error Occurred 2] - Retrieving User Profile");
                }
            });
        }

    mockLoginviewmodel.authenticateUser("abc@gmail.com","123456");
  //  verify(mockAuth).createuserWithEmailAndPassword("abc@gmail.com","123456");

    }
}

我收到此错误。

org.objenesis.ObjenesisException: java.lang.reflect.InvocationTargetException

调用视图模型测试firebas登录注册功能的错误是什么。请告诉我。提前致谢。
