如何在小部件测试中包含提供者？

Question

我有一个依赖提供商的小部件。我想运行在此小部件上进行小部件测试。我假设因为 widget 测试直接在树中的那个节点上进行，所以出现如下错误是合理的：

  * Ensure the Provider<Appointments> is an ancestor to this InstallMonitorPage Widget

(注意：我的Provider名称是.可能主要包括：

 return MultiProvider(
      providers: [
        Provider<AuthBase>(
          builder: (context) => Auth(),
        ),
        Provider<Appointments>(
          builder: (context) => Appointments(),
        )
      ],
      child: MaterialApp(
          title: title,
          theme: ThemeData(
            primarySwatch: Colors.blue,
          ),
          home: LaunchPage()),
    );

当运行对小部件树下方的小部件进行小部件测试时，是否有 syntax/way 来包含提供程序？

Answer 1

您可以尝试这样的操作：

    await tester.pumpWidget(MultiProvider(
         providers: [
        Provider<AuthBase>(
          builder: (context) => Auth(),
        ),
        Provider<Appointments>(
          builder: (context) => Appointments(),
         )
       ],
      child: Builder(
        builder: (_) => YourWidgeToTest(),
      ),
    ),);
