Question

依赖项：

//Room
implementation 'android.arch.lifecycle:extensions:1.1.1'
implementation 'android.arch.persistence.room:runtime:1.1.1'
kapt 'android.arch.lifecycle:compiler:1.1.1'
kapt 'android.arch.persistence.room:compiler:1.1.1'

android测试类：

@RunWith(AndroidJUnit4::class)
class SampleTest {

    private lateinit var appDatabase: AppDatabase

    @Before
    fun initDb() {
        appDatabase = Room.inMemoryDatabaseBuilder(InstrumentationRegistry.getContext(), AppDatabase::class.java)
                .allowMainThreadQueries()
                .build()
    }

    @Test
    fun sampleTest() {
    }    
}

运行此测试类时的错误：

Room.inMemoryDatabaseBuilder() not found in instrumented test

Room Persistence Library run time exception when calling Rooms inMemoryBuilder method

这两个帖子中的问题相似或相同，但是我花了半天的时间来解决这个问题，但还是没有运气。有谁知道导致此错误的原因以及解决方法？
