Integration_test 迁移后无法通过启动屏幕

but*_*oys 6 integration-testing splash-screen flutter

我的集成测试正在使用 flutter_driver，但在按照文档迁移到integration_test之后，我无法通过启动屏幕。

\n

下面是一个简单的测试。如果不使用，sleep我永远不会越过Test starting...屏幕，正如其他人在这里发现的那样。随着sleep测试通过Test starting...，但随后卡在了我的启动屏幕上。不确定是否相关，但我的身份验证屏幕位于启动屏幕之后。

import \'dart:io\';\nimport \'package:flutter/widgets.dart\';\nimport \'package:flutter_test/flutter_test.dart\';\nimport \'package:integration_test/integration_test.dart\';\nimport \'../lib/main.dart\' as app;\n\nvoid main() {\n  IntegrationTestWidgetsFlutterBinding.ensureInitialized();\n\n  testWidgets(\'verify users\', (WidgetTester tester) async {\n    app.main();\n\n    sleep(const Duration(seconds: 10));\n\n    await tester.pumpAndSettle();\n\n    final Finder menuButtonFinder = find.byKey(const Key(\'kKeyButtonMenu\'));\n\n    expect(menuButtonFinder, findsOneWidget);\n  });\n}\n
