unit-testing - 找不到符号导入 dagger.hilt.android.internal.Contexts

Question

我正在尝试为 Dagger_Hilt (hilt-android-testing:2.38.1) 编写测试，但不幸的是，当我运行测试时发生了此错误。我不明白有什么问题。如果有人能帮助我解决这个错误，那将会有很大帮助。

cannot find symbol import dagger.hilt.android.internal.Contexts; ^

symbol: class Contexts location: package dagger.hilt.android.internal

ShoppingDaoTest.kt 类:

    @ExperimentalCoroutinesApi
    @SmallTest
    @HiltAndroidTest
    class ShoppingDaoTest {

       @get:Rule
       var hileRule = HiltAndroidRule(this)

       @get:Rule
       var instantTaskExecutorRule = InstantTaskExecutorRule()

       @Inject
       @Named("test_db")
       lateinit var database: ShoppingItemDatabase
   
       private lateinit var dao: ShoppingDao

       @Before
       fun setup() {
         hileRule.inject()
         dao = database.shoppingDao()
       }

      @After
      fun teardown() {
        database.close()
      }

  
    @Test
    fun insertShoppingItem() = runBlockingTest {
        val shoppingItem = ShoppingItem("name", 1, 1f, "url", id = 1)
        dao.insertShoppingItem(shoppingItem)

        val allShoppingItems = dao.observeAllShoppingItems().getOrAwaitValue()

        assertThat(allShoppingItems).contains(shoppingItem)

    }
}

TestModule.kt 类:

@Module
@InstallIn(SingletonComponent::class)
object TestAppModule {

    @Provides
    @Named("test_db")
    fun provideinMemoryDb(
        @ApplicationContext context: Context
    ) = Room.inMemoryDatabaseBuilder(context, ShoppingItemDatabase::class.java)
        .allowMainThreadQueries()
        .build()


}

HiltTestRunner.kt 类:

class  HiltTestRunner : AndroidJUnitRunner() {

    override fun newApplication(
        cl: ClassLoader?,
        className: String?,
        context: Context?
    ): Application {
       // return super.newApplication(cl, className, context)
         return super.newApplication(cl, HiltTestApplication::class.java.name, context)
    }
}

和 build.gradle 设置:

android {
  defaultConfig {
    ...
    testInstrumentationRunner "com.mypackage.name.HiltTestRunner"
  }
}

 dependencies{
  ...

Answer 1

我遇到了同样的问题，查看我的代码，我注意到我的 dagger-hilt 类路径项目位于 2.36，因此我更新到 2.38.1 并检查所有 hilt 依赖项是否具有相同的版本(否则错误会一次又一次地发生)您必须清除并重建项目。我希望这个解决方案适合您!

类路径插件:

classpath "com.google.dagger:hilt-android-gradle-plugin:2.38.1"

Dagger 柄:

kapt "com.google.dagger:hilt-android-compiler:2.38.1"
implementation "com.google.dagger:hilt-android:2.38.1"

Dagger 柄测试:

androidTestImplementation 'com.google.dagger:hilt-android-testing:2.38.1'
kaptAndroidTest 'com.google.dagger:hilt-android-compiler:2.38.1'
