我正在我的应用程序中使用会议室数据库。我的应用程序中具有登录功能,在获取用户名和密码后,单击Login button
后,我正在从成功获得回调响应后调用API并将响应数据存储在会议室数据库表中 API。
现在,我想编写数据库数据的集成测试用例,在这里我使用 mockWebServer 模拟API响应并将其存储在会议室数据库表中。
然后我获取数据库值并测试这些值是否正确存储,但是我遇到了错误
java.lang.IllegalStateException:无法访问主线程上的数据库,因为它可能会长时间锁定UI。
在这一行上 authentication = authenticationDao.getAuthInformation();
下面是我的测试用例代码:
@RunWith(AndroidJUnit4.class)
@FixMethodOrder(MethodSorters.NAME_ASCENDING)
public class TestLogin {
@Rule
public InstantTaskExecutorRule mInstantTaskExecutorRule = new InstantTaskExecutorRule();
@Rule
public ActivityTestRule<LoginActivity> activityTestRule = new ActivityTestRule<>(LoginActivity.class, true, false);
@Rule
public MockWebServerTestRule mockWebServerTestRule = new MockWebServerTestRule();
@Mock
Application application;
LoginViewModel loginViewModel;
AppDatabase appDatabase;
AuthenticationDao authenticationDao;
Authentication authentication;
@Before
public void setUp() throws Exception {
MockitoAnnotations.initMocks(this);
loginViewModel = new LoginViewModel(application);
ApiUrls.TOKEN = mockWebServerTestRule.mockWebServer.url("/").toString();
appDatabase = Room.inMemoryDatabaseBuilder(InstrumentationRegistry.getContext(),
AppDatabase.class).build();
authenticationDao = appDatabase.authenticationDao();
activityTestRule = new ActivityTestRule<>(LoginActivity.class, true, true);
String fileName = "valid_login_response.json";
mockWebServerTestRule.mockWebServer.enqueue(new MockResponse()
.setBody(RestServiceTestHelper.getStringFromFile(getContext(), fileName))
.setResponseCode(HttpURLConnection.HTTP_OK));
Intent intent = new Intent();
activityTestRule.launchActivity(intent);
loginViewModel.userName.postValue("Elon");
loginViewModel.password.postValue("Musk123");
loginViewModel.getAuthenticateTokenData();
mockWebServerTestRule.mockWebServer.takeRequest();
}
@Test
public void a_testDbEntryOnValidResponse() {
authentication = authenticationDao.getAuthInformation();
String issueTime = authentication.getIssueDateTime();
String expirationTime = authentication.getExpireDateTime();
String refreshToken = authentication.getRefreshToken();
Assert.assertEquals("Tue, 16 Apr 2019 10:39:20 GMT", issueTime);
Assert.assertEquals("Tue, 16 Apr 2019 10:54:20 GMT", expirationTime);
Assert.assertEquals("e2b4dfd7205587745aa3100af9a0b", refreshToken);
}
}
下面是我的AppDatabase
班:
@Database(entities = {Authentication.class, UserProfile.class}, version = 1, exportSchema = false)
public abstract class AppDatabase extends RoomDatabase {
private static AppDatabase INSTANCE;
public static AppDatabase getAppDatabase(Context context) {
if (INSTANCE == null) {
INSTANCE =
Room.databaseBuilder(context,
AppDatabase.class,
"myapp-database")
.allowMainThreadQueries()
.build();
}
return INSTANCE;
}
public abstract AuthenticationDao authenticationDao();
public abstract UserProfileDao userProfileDao();
}
可能是什么问题? 我的测试用例正确吗?
谢谢。
