Android Unit test with Room database error

Time：01-24

Writing unit test to insert object to room database, take it from database and assert are the 2 mentioned equal. Here is the code:

@RunWith(AndroidJUnit4::class)
@SmallTest
class GdprDaoTest {

    private lateinit var dao: GdprDao
    private lateinit var database: AppDatabase

    @get:Rule
    val instantTaskExecutorRule = InstantTaskExecutorRule()

    @Before
    fun setup() {
        database = Room.inMemoryDatabaseBuilder(
            ApplicationProvider.getApplicationContext(),
            AppDatabase::class.java
        ).allowMainThreadQueries().build()


        dao = database.gdprDao()
    }


    @Test
    fun insertConfiguration(){
        runBlocking {
            val insertedGdprEntity =
                GdprEntity(id = 1, conditionsUrl = "conditionsUrl", agreementUrl = "AgreementUrl")
            dao.insert(insertedGdprEntity)

            var fetchedGdprEntity = dao.getGdpr().getOrAwaitValue()

            assertEquals(insertedGdprEntity, fetchedGdprEntity)


        }
    }

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

}

But this does not work. When I debug, it fails on the line dao.insert(insertedGdprEntity). In debug I can see that do is instantiated (it is not null). Looks pretty straight forward code to me, am I missing something? Here is the error I get from stacktrace:

System.logW: A resource was acquired at attached stack trace but never released. See java.io.Closeable for information on avoiding resource leaks.java.lang.Throwable: Explicit termination method 'close' not called

CodePudding user response：

As already discussed the solution is to increase the version of robolectric to 4.9 as described in this issue https://github.com/robolectric/robolectric/issues/7590

All that is needed to be done is update to:

testImplementation "org.robolectric:robolectric:4.9"

And:

testOptions { unitTests.includeAndroidResources = true }
