DriverError: Failed to fulfill Tap due to remote error flutter
DriverError: Failed to fulfill Tap due to remote error flutter
我有一些自定义的 TextFiels，它们用于输入 PIN，我将它们命名为 PinInputField。当我 运行 使用 flutter drive 进行集成测试时，所有输入字段都将收到给定的文本，最后一个除外并停止 运行 测试。
这是代码：
P.s：我正在使用 HookWidget
final focusNodes = List.generate(6, (_) => new FocusNode());
final values = List.generate(6, (_) => useState<String>(''));
Row(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
for (int i = 0; i < values.length; i++)
PinInputField(
key: ValueKey('$i'),
width: MediaQuery.of(context).size.width / 11.71,
height: 80,
fontSize: 50,
marginRight: 16,
input: values[i],
focusNode: focusNodes[i],
nextFocusNode: i == 5 ? null : focusNodes[i + 1],
)
],
)
这是测试:
test('test main card settings items', () async {
final cardSettingsItem = find.byValueKey('settings.cardSettings');
final mainSettingsList = find.byValueKey('mainSettingsList');
final profileButton = find.byValueKey('Profile');
final changePinButton = find.byValueKey('Cambiar pin');
final changePinInputField0 = find.byValueKey('0');
final changePinInputField1 = find.byValueKey('1');
final changePinInputField2 = find.byValueKey('2');
final changePinInputField3 = find.byValueKey('3');
final changePinInputField4 = find.byValueKey('4');
final changePinInputField5 = find.byValueKey('5');
final changePinScreenButton = find.byValueKey('changePinScreenButton');
sleep(Duration(seconds: 3));
await driver.tap(profileButton);
sleep(Duration(seconds: 2));
await driver.scrollIntoView(mainSettingsList);
sleep(Duration(seconds: 3));
await driver.tap(cardSettingsItem);
sleep(Duration(seconds: 3));
await driver.tap(changePinButton);

await driver.enterText("5");
sleep(Duration(seconds: 5));
await driver.tap(changePinScreenButton);
sleep(Duration(seconds: 4));
});
这是日志：

这个问题主要发生在测试未真正完成就超时的情况下。用于 运行 测试的默认超时为 30 秒，此处您的睡眠持续时间加起来超过 30 秒，因此连接因未决请求而关闭。
我不明白为什么每次动作后都要睡一段时间，也许你可以reduce/remove睡觉。如果睡眠对于您的情况是强制性的，请尝试将适当的 timeout 传递给测试。
示例：
test(
'test main card settings items',
() async {
final cardSettingsItem = find.byValueKey('settings.cardSettings');
final mainSettingsList = find.byValueKey('mainSettingsList');
final profileButton = find.byValueKey('Profile');
final changePinButton = find.byValueKey('Cambiar pin');
final changePinInputField0 = find.byValueKey('0');
final changePinInputField1 = find.byValueKey('1');
final changePinInputField2 = find.byValueKey('2');
final changePinInputField3 = find.byValueKey('3');
final changePinInputField4 = find.byValueKey('4');
final changePinInputField5 = find.byValueKey('5');
final changePinScreenButton = find.byValueKey('changePinScreenButton');
sleep(Duration(seconds: 3));
await driver.tap(profileButton);
sleep(Duration(seconds: 2));
await driver.scrollIntoView(mainSettingsList);
sleep(Duration(seconds: 3));
await driver.tap(cardSettingsItem);
sleep(Duration(seconds: 3));
await driver.tap(changePinButton);
sleep(Duration(seconds: 4));
await driver.tap(changePinInputField0);
sleep(Duration(seconds: 2));
await driver.enterText("0");
sleep(Duration(seconds: 1));
await driver.tap(changePinInputField1);
sleep(Duration(seconds: 2));
await driver.enterText("1");
sleep(Duration(seconds: 1));
await driver.tap(changePinInputField2);
sleep(Duration(seconds: 2));
await driver.enterText("2");
sleep(Duration(seconds: 1));
await driver.tap(changePinInputField3);
sleep(Duration(seconds: 2));
await driver.enterText("3");
sleep(Duration(seconds: 1));
await driver.tap(changePinInputField4);
sleep(Duration(seconds: 2));
await driver.enterText("4");
sleep(Duration(seconds: 4));
await driver.tap(changePinInputField5);
sleep(Duration(seconds: 1));
await driver.enterText("5");
sleep(Duration(seconds: 5));
await driver.tap(changePinScreenButton);
sleep(Duration(seconds: 4));
},
timeout: Timeout(
Duration(minutes: 2),

);
希望对您有所帮助！
我也一直在为默认的 30 秒超时设置而苦恼。只有当 Flutter Driver 测试在远程 CI/CD 上 运行 时才会出现问题。本地测试 运行 很棒。我做了两件事似乎适用于远程 CI/CD:
- 指定了上面规定的
timeout @Hemanth。谢谢@Hemanth！
- 在每个测试开始时添加
clearTimeline()。
test('Home page should properly work', () async {
await driver.clearTimeline();
await HomePage(driver).appears()
.then((a) => a.exploreHomePage());
},
timeout: Timeout(
Duration(minutes: 2),
),
);
注意：
实施 timeout & clearTimeline() 允许完成更长的 运行ning 测试。但我建议无论大小如何都添加到每个测试中。我最初也尝试过 sleeps，并最终在使用 timeout & clearTimeline().
后将它们全部删除
希望这对您有所帮助。
我希望我的发现能够帮助到别人。
我收到错误“DriverError：由于远程错误无法实现 Tap”和“VMServiceFlutterDriver：tap 消息需要很长时间才能完成。”
就我而言，Flutter Driver 无法找到要测试的小部件，因为我使用的是 'find.byType'。有一次，我为所有小部件提供了密钥，并传递给使用 'find.byValueKey'，小部件已本地化并且一切正常。
那是我的代码：
void main() {
group('reversor app integration test', () {
FlutterDriver driver;
setUpAll(() async {
driver = await FlutterDriver.connect();
});
tearDownAll(() {
if (driver != null) {
driver.close();
}
});
// find.byType was the cause for the error 'DriverError: Failed to fulfill Tap due to remote error'
// Given key for the three below widgets, and after hat using 'find.byValueKey', solved the problem
var field = find.byValueKey("TextField");
var btn = find.byValueKey("button");
var reverse = find.byValueKey("response");
test('Reversing the string', () async {
await driver.clearTimeline();
await driver.tap(field);
await driver.enterText("Hello222");
await driver.waitForAbsent(reverse);
await driver.tap(btn);
await driver.waitFor(reverse);
await driver.waitUntilNoTransientCallbacks();
assert(reverse != null);
});
});
