android - 用于 UI 测试的 Hilt 依赖注入(inject)说 "HiltAndroidRule"没有添加，但它是

Question

我正在尝试使用 Hilt 进行依赖注入(inject)，但它给出了错误 java.lang.IllegalStateException: The component was not created. Check that you have added the HiltAndroidRule.虽然添加了 HiltAndroidRule:

@RunWith(AndroidJUnit4.class)
@UninstallModules(ItemsModule.class)
@HiltAndroidTest
public class SelectItemActivityTest {

    @Rule
    public HiltAndroidRule hiltRule = new HiltAndroidRule(this);

    @Before
    public void init() {
        hiltRule.inject();
    }
    @BindValue
    List<Item> items = getItems();
    List<Item> getItems()  {
        List<Item> items = new ArrayList<>();
        items.add(new Item(1, "Item1", "", true, true, true));;
        items.add(new Item(2, "Item2", "", true, true, true));;
        items.add(new Item(3, "Item3", "", true, true, true));;
        return items;
    }

    @Rule
    public ActivityTestRule<SelectItemActivity> mActivityRule =
            new ActivityTestRule<>(SelectItemActivity.class);

    @Test
    public void text_isDisplayed() {
        onView(withText("Item1")).check(matches(isDisplayed()));
    }
}

我也尝试在类中添加一个 ItemsModule ，但结果相同。

您必须使用 RuleChain 包装它或申请 order Rule 的参数注解。
