我正在嘗試測試我的一個名為 Store 的類，特別是下面名為 removeFromFavourite 的方法是該方法    public void removeFromFavourite(Quote quote) {        if(quote == null) {            throw new IllegalArgumentException("Quote can't be null");        }        if (quote.getId() <1) {            throw new IllegalArgumentException("Quote id can't be less than 1");        }        realm.beginTransaction();        QuoteRealMObject object = realm.where(QuoteRealMObject.class).                equalTo(QuoteRealMObject.ID, quote.getId()).findFirst();        if(object != null) {            deleteObject(object);        }        realm.commitTransaction();    }    private void deleteObject(RealmObject object) {        object.deleteFromRealm();    }我創建了 deleteObject 方法來調用 deleteFromRealm，因為 deleteFromRealm 是最終的，因此我無法模擬它。我的期望是通過創建間諜來模擬對“deleteObject”ob Store 對象的調用這是我的@Before方法private Realm mockedRealm;private Store store;@Beforepublic void setUp() throws Exception {    mockedRealm = Mockito.mock(Realm.class);    store = new Store(mockedRealm);    store = PowerMockito.spy(store);}所以我創建了一個 Realm 的模擬對象并使用它來創建類 Store 的對象，然后從 store 的對象中創建一個間諜并將其分配回 store 對象本身。以下是 removeFromFavourite 的測試方法@Test    public void removeFromFavourite() throws Exception {        Quote quot = new Quote();        quot.setId(1);        RealmQuery<QuoteRealMObject> query = Mockito.mock(RealmQuery.class);        RealmQuery<QuoteRealMObject> filteredQuery = Mockito.mock(RealmQuery.class);        Mockito.when(mockedRealm.where(QuoteRealMObject.class)).thenReturn(query);        Mockito.when(query.equalTo(QuoteRealMObject.ID, 1)).thenReturn(filteredQuery);        QuoteRealMObject mockedObject = Mockito.mock(QuoteRealMObject.class);        Mockito.when(filteredQuery.findFirst()).thenReturn(mockedObject);        PowerMockito.doNothing().when(store, "deleteObject", mockedObject);                    store.removeFromFavourite(quot);    }這里的行PowerMockito.doNothing().when(store, "deleteObject", mockedObject);本身正在調用真正的私有方法“deleteObject”，我得到未完成的模擬異常
