Android 领域单元测试问题

Question

使用 JUnit4 Test Runner，测试运行并且似乎有效，但查询 returns 没有结果：

@RunWith(AndroidJUnit4::class)
class LocationViewInstrumentationTest {

@Rule
public val mActivityRule: ActivityTestRule<MapsActivity> = ActivityTestRule(MapsActivity::class.java)

@Rule
var testFolder = TemporaryFolder()


@Test
fun mapViewIsRendered() {
    onView(withId(R.id.map)).check(matches(isDisplayed()))
}

@Test
@Throws(IOException::class)
fun canSaveLocation() {
    val tempFolder = testFolder.newFolder("realmdata")
    val config = RealmConfiguration.Builder(tempFolder).build()
    val realm = Realm.getInstance(config)

    realm.beginTransaction()
    val location = Location("Poppy Manor", 33.2, -121.3, 0.0)

    assertThat(location, not(nullValue()))

    realm.commitTransaction()

    RealmQuery<Location> query = realm.where(Location.class);
    RealmResults<Location> results = query.findAll();
    assertThat(results.size(), equalTo(1));

}

是的，我查看了示例项目，但不想添加所有依赖项并希望我的测试可读，因此也尽量避免所有模拟。

您没有在交易中写入 Realm。尝试在 realm.commitTransaction() 之前添加 realm.copyToRealm(location)。
