问题描述
我有 3 个不同的文件/屏幕（主、登录和注册），其中登录和注册是 statefulwidgtes。我想在屏幕中执行小部件测试，但是，似乎我无法在登录和注册下获取小部件，每次尝试时我都会收到消息：
预期：小部件树中正好有一个匹配的节点 实际：_WidgetTypeFinder: 其中：表示没有找到，但预期有一个
请注意，在上面的示例中，ListView 小部件实际上存在，但未被测试人员定位。
这是主要部件的代码

}
import 'package:Flutter/material.dart';
import 'package:Flutter_test/Flutter_test.dart';
import 'package:loginscreen/setup/login.dart';
void main() {
testWidgets(' ',(WidgetTester tester) async {
// add it to the widget tester
await tester.pumpWidget(LoginPage());
expect(find.byType(Text),findsOneWidget);
});
}
所以我的问题是，如何测试登录并注册有状态的小部件？如何在这些屏幕中获取小部件？flu
