用integration_test软件包设置颤振综合测试的现场

Question

我正在尝试使用在运行测试之前设置特定语言环境的integration_test包来编写一个测试。

    await tester.binding.setLocale('en', 'US');
    app.main();
    await tester.idle();
    await tester.pumpAndSettle();

    // The app is still using the default locale of the phone...

下面是我在驱动程序中的当前设置：

  // Some adb commands for granting permissions...
  print('Starting test.');
  final FlutterDriver driver = await FlutterDriver.connect();
  final String data = await driver.requestData(
    null,
    timeout: const Duration(minutes: 1),
  );
  await driver.close();
  // Some more adb commands to revoke permissions.

这似乎行不通。

我找到了this issue here，但它没有使用integration_test包，因此具有完全不同的设置。

我能够通过将我的目标小部件包装在Localizations小部件中来本地化我的集成测试。类似于：

class WidgetTestWrapper extends StatelessWidget {
  const WidgetTestWrapper({
    Key? key,
    required this.locale,
    required this.child,
  }) : super(key: key);

  final Widget child;
  final Locale locale;

  static const localizationsDelegates = <LocalizationsDelegate>[
    S.delegate,
    GlobalMaterialLocalizations.delegate,
    GlobalWidgetsLocalizations.delegate,
    GlobalCupertinoLocalizations.delegate,
  ];

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Material(
        child: Localizations(
          locale: locale,
          delegates: localizationsDelegates,
          child: child,
        ),
      ),
    );
  }
}

然后，我在对runApp的调用中传入测试所需的Locale。

例如，对于西班牙语US (es-US)：

runApp(WidgetTestWrapper(locale: const Locale('es', 'US'), child: widgetUnderTest));
