因此，我正在尝试测试我的flutter应用程序。这是我的工作
from pydrive2.auth import GoogleAuth
from pydrive2.drive import GoogleDrive
gauth = GoogleAuth()
gauth.CommandLineAuth()
drive = GoogleDrive(gauth)
file_list = drive.ListFile({'q': "'XXXXXXXXXXXXXXXXXXXXXXXX' in parents and trashed=false"}).GetList()
for file2 in file_list:
string = "'"+ file2['id'] +"'" + " in parents and trashed=false"
file_list2 = drive.ListFile({'q': string}).GetList()
print(file2['title'], file2['id'])
for file3 in file_list2:
file3.GetContentFile('/data/' + file3['title'])
print('downloaded: ', file3['title'], file3['id'])
这是我的class MockSplashScreenBloc extends MockBloc<SplashScreenState>
implements SplashScreenBloc {}
void main() {
MockSplashScreenBloc splashScreenBloc;
Widget MyWidget() {
return MaterialApp(
home: BlocProvider(
create: (context) {
return SplashScreenBloc(url: "google.com");
},
child: SplashScreen(),
),
);
}
group('Splash Screen Widget Test', () {
setUp(() {
splashScreenBloc = MockSplashScreenBloc();
});
tearDown(() {
splashScreenBloc?.close();
});
testWidgets('should render Container when state is Default State',
(WidgetTester tester) async {
when(splashScreenBloc.state).thenAnswer((_) => Default());
await tester.pumpWidget(MyWidget());
expect(find.byKey(ValueKey("container_empty")), findsOneWidget);
});
testWidgets('should render LoadingIndicator when state is Loading State',
(WidgetTester tester) async {
when(splashScreenBloc.state).thenReturn(LoadingState());
await tester.pumpWidget(MyWidget());
expect(find.byKey(ValueKey("splash_loading_bar")), findsOneWidget);
});
});
}
SplashScreen我无法通过此测试class SplashScreen extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: BlocBuilder<SplashScreenBloc, SplashScreenState>(
builder: (context, state) {
if (state is LoadingState) {
return CircularProgressIndicator(
key: Key("splash_loading_bar"),
);
} else if (state is NotConnected) {
return Text("Could not connect to server",
key: ValueKey("splash_screen_not_connected"));
} else if (state is Connected) {
return Text(
"Connected",
key: Key("splash_screen_connected"),
);
} else {
return Container(key: Key("container_empty"));
}
},
),
),
);
}
}
，我很努力尝试使用should render LoadingIndicator when state is Loading State，但仍然无法正常工作，这是错误消息
══╡颤振测试框架引起的异常 ╞═════════════════════════════════════════════════ following以下 抛出TestFailure对象运行测试：预期：正好一个 小部件树中的匹配节点实际：_KeyFinder：<零小部件 使用键[<'splash_loading_bar'>]（忽略后台小部件）>

我该如何解决？
答案 0 :(得分：1)
您尝试等待tester.pumpAndSettle（）吗？
tester.pump（）
在给定的持续时间后触发窗口小部件的重建。tester.pumpAndSettle（）
重复调用给定持续时间的泵，直到没有 更长的预定帧。这基本上等待所有动画 完成。
请尝试以下代码：
testWidgets('should render LoadingIndicator when state is Loading State',
(WidgetTester tester) async {
when(splashScreenBloc.state).thenReturn(LoadingState());
await tester.pumpWidget(MyWidget());
await tester.pumpAndSettle();
expect(find.byKey(ValueKey("splash_loading_bar")), findsOneWidget);
});
