我正在學習 Flutter 的單元測驗。我的應用程式中有一個使用 Google 登錄的功能包，我想對其進行單元測驗。
我已經走到一半了，但我有點不知道如何處理這個錯誤。
'package:firebase_auth_platform_interface/src/providers/google_auth.dart': Failed assertion: line 43 pos 12: 'accessToken != null || idToken != null': At least one of ID token and access token is required
dart:core _AssertionError._throwNew
package:firebase_auth_platform_interface/src/providers/google_auth.dart 43:12 GoogleAuthProvider.credential
package:firebase_auth_client/src/firebase_auth_client.dart 107:45 FirebaseAuthClient.signInWithGoogle
===== asynchronous gap ===========================
dart:async _CustomZone.registerUnaryCallback
package:firebase_auth_client/src/firebase_auth_client.dart 97:26 FirebaseAuthClient.signInWithGoogle
test/src/firebase_auth_client_test.dart 101:30 main.<fn>.<fn>.<fn>
我的測驗腳本是這樣的
class FakeUserCredential extends Fake implements UserCredential {}
class MockFirebaseAuth extends Mock implements FirebaseAuth {}
class MockGoogleSignIn extends Mock implements GoogleSignIn {}
class MockGoogleSignInAccount extends Mock implements GoogleSignInAccount {}
class MockGoogleSignInAuthentication extends Mock
implements GoogleSignInAuthentication {}
class MockOAuthCredential extends Mock implements OAuthCredential {}
void main() {
late FirebaseAuth firebaseAuth;
late UserCredential userCredential;
late FirebaseAuthClient firebaseAuthClient;
late GoogleSignIn googleSignIn;
late GoogleSignInAccount googleSignInAccount;
late GoogleSignInAuthentication googleSignInAuthentication;
late OAuthCredential oAuthCredential;
setUp(() {
firebaseAuth = MockFirebaseAuth();
userCredential = FakeUserCredential();
googleSignIn = MockGoogleSignIn();
googleSignInAccount = MockGoogleSignInAccount();
oAuthCredential = MockOAuthCredential();
googleSignInAuthentication = MockGoogleSignInAuthentication();
firebaseAuthClient = FirebaseAuthClient(
auth: firebaseAuth,
googleSignIn: googleSignIn,
);
});
group('FirebaseAuthClient', () {
// passing tests omitted...
group('SignIn', () {
// passing tests omitted...
test('with google completes', () async {
when(() => googleSignIn.signIn()).thenAnswer(
(_) async => googleSignInAccount,
);
when(() => googleSignInAccount.authentication).thenAnswer(
(_) async => googleSignInAuthentication,
);
when(
() => firebaseAuth.signInWithCredential(oAuthCredential),
).thenAnswer((_) async => userCredential);
expect(
firebaseAuthClient.signInWithGoogle(),
completes,
);
});
// passing tests omitted...
});
// passing tests omitted...
});
}
這是我寫的包。
import 'package:firebase_auth/firebase_auth.dart';
import 'package:google_sign_in/google_sign_in.dart';
/// {@template firebase_auth_client_exception}
/// Abstract class to handle the firebase auth client exceptions.
/// {@endtemplate}
abstract class FirebaseAuthClientException implements Exception {
/// {@macro firebase_auth_client_exception}
const FirebaseAuthClientException(this.error);
/// The error which was caught.
final Object error;
}
/// {@template firebase_sign_in_failure}
/// Thrown during the sign in process if a failure occurs.
/// {@endtemplate}
class FirebaseSignInFailure extends FirebaseAuthClientException {
/// {@macro firebase_sign_in_failure}
const FirebaseSignInFailure(super.error);
/// Construct error messages from the given code.
factory FirebaseSignInFailure.fromCode(String code) {
switch (code) {
case 'invalid-email':
return const FirebaseSignInFailure(
'Email address is invalid.',
);
case 'user-disabled':
return const FirebaseSignInFailure(
'Your account is disabled.',
);
case 'user-not-found':
return const FirebaseSignInFailure(
'Unable to find your account.',
);
case 'wrong-password':
return const FirebaseSignInFailure(
'You have entered the wrong password.',
);
default:
return const FirebaseSignInFailure(
'An unknown error occurred.',
);
}
}
@override
String toString() => error.toString();
}
/// {@template firebase_sign_out_failure}
/// Thrown during the sign out process if a failure occurs.
/// {@endtemplate}
class FirebaseSignOutFailure extends FirebaseAuthClientException {
/// {@macro firebase_sign_out_failure}
const FirebaseSignOutFailure(super.error);
}
/// {@template firebase_auth_client}
/// Firebase auth client
/// {@endtemplate}
class FirebaseAuthClient {
/// {@macro firebase_auth_client}
const FirebaseAuthClient({
required FirebaseAuth auth,
required GoogleSignIn googleSignIn,
}) : _auth = auth,
_googleSignIn = googleSignIn;
final FirebaseAuth _auth;
final GoogleSignIn _googleSignIn;
// unrelated methods omitted...
/// Sign the user in using Google auth provider.
Future<UserCredential> signInWithGoogle() async {
try {
final googleUser = await _googleSignIn.signIn();
final googleAuth = await googleUser?.authentication;
if (googleAuth == null) {
Error.throwWithStackTrace(
const FirebaseSignInFailure('Sign In Cancelled.'),
StackTrace.current,
);
}
final credential = GoogleAuthProvider.credential(
accessToken: googleAuth.accessToken,
idToken: googleAuth.idToken,
);
return await _auth.signInWithCredential(credential);
} on FirebaseException catch (error, stackTrace) {
Error.throwWithStackTrace(
FirebaseSignInFailure.fromCode(error.code),
stackTrace,
);
} catch (error, stackTrace) {
Error.throwWithStackTrace(FirebaseSignInFailure(error), stackTrace);
}
}
// unrelated methods omitted...
}
我曾經試圖覆寫這樣的屬性MockGoogleSignInAuthentication，但它不起作用。
class MockGoogleSignInAuthentication extends Mock
implements GoogleSignInAuthentication {
@override
String? get idToken => 'fakeId';
@override
String? get accessToken => 'fakeToken';
}
有人可以為此指出正確的方向嗎？提前致謝！
uj5u.com熱心網友回復：
您可以使用google_sign_in mocks 包進行 google auth mock

對于那些想知道我如何使用用戶 SHYAM 提到的包實施測驗的人。
這是我的完整測驗腳本的樣子。
