Mocks for google_sign_in. Use this package with firebase_auth_mocks to write unit tests involving Firebase Authentication.

Usage

A simple usage example:

import 'package:google_sign_in_mocks/google_sign_in_mocks.dart';
import 'package:test/test.dart';

void main() {
  late MockGoogleSignIn googleSignIn;
  setUp(() {
    googleSignIn = MockGoogleSignIn();
  });

  test('should return idToken and accessToken when authenticating', () async {
    final signInAccount = await googleSignIn.signIn();
    final signInAuthentication = await signInAccount!.authentication;
    expect(signInAuthentication, isNotNull);
    expect(googleSignIn.currentUser, isNotNull);
    expect(signInAuthentication.accessToken, isNotNull);
    expect(signInAuthentication.idToken, isNotNull);
  });

  test('should return null when google login is cancelled by the user',
      () async {
    googleSignIn.setIsCancelled(true);
    final signInAccount = await googleSignIn.signIn();
    expect(signInAccount, isNull);
  });
  test('testing google login twice, once cancelled, once not cancelled at the same test.', () async {
   googleSignIn.setIsCancelled(true);
    final signInAccount = await googleSignIn.signIn();
    expect(signInAccount, isNull);
    googleSignIn.setIsCancelled(false);
    final signInAccountSecondAttempt = await googleSignIn.signIn();
    expect(signInAccountSecondAttempt, isNotNull);
  });
}
