Flutter 如何在颤振综合试验中看到失效线的线号？
编辑：在颤振问题列表中找到问题： 当颤振驱动-集成测试出现故障时，我在哪里查找-故障发生时的线号？我似乎在颤振驱动输出中找不到它 如有任何帮助/建议，将不胜感激。 提前谢谢 使用的命令：颤振驱动-目标=测试驱动程序/app.dart 输出：Flutter 如何在颤振综合试验中看到失效线的线号？,flutter,integration-testing,flutterdriver,Flutter,Integration Testing,Flutterdriver,编辑：在颤振问题列表中找到问题： 当颤振驱动-集成测试出现故障时，我在哪里查找-故障发生时的线号？我似乎在颤振驱动输出中找不到它 如有任何帮助/建议，将不胜感激。 提前谢谢 使用的命令：颤振驱动-目标=测试驱动程序/app.dart 输出： Warning: You are using these overridden dependencies: ! pedantic 1.10.0-nullsafety

There is no way you can find an error line from Console Output, the best way to debug your code for error is to add a print statement before every driver
action, this is what I have found when I tried to find any solutions regarding this issue, test will look like this just added snippet of one of my tests:
test('sign up test, log in button on sign up is working', () async {
print('Sign-up test started');
print('Waiting for join now button');
await driver.waitFor(loginpage.joinNowButtonFinder);
print('Tap for join now button');

您无法从控制台输出中找到错误行，调试错误代码的最佳方法是在每个驱动程序操作之前添加一个print语句，这是我在尝试找到有关此问题的任何解决方案时发现的，测试将类似于刚刚添加的一个测试片段：
$env:VM_SERVICE_URL = adb logcat -d | `
Select-String -Pattern "Observatory listening on (.*)" | `
select-object -Last 1 | foreach-object { $_.Matches.Groups[1].Value }
$port = $env:VM_SERVICE_URL | `
Select-String -Pattern ".*\d:(\d*)/" | `
select-object -Last 1 | `
foreach-object { $_.Matches.Groups[1].Value }
adb forward tcp:$port tcp:$port
flutter packages pub run test $args
您可以将测试附加到正在运行的Flatter应用程序。您需要设置VM_SERVICE_URL环境变量，然后使用其他命令运行测试
在Windows中，您可以使用此内容创建ps1文件，并在设备或虚拟机上启动应用程序后运行该文件：
export VM_SERVICE_URL=$(adb logcat -d | grep -o -E "Observatory listening on (.*)" | tail -1 | cut -d" " -f 4)
port=$(echo $VM_SERVICE_URL | cut -d: -f3 | cut -d/ -f1)
adb forward tcp:$port tcp:$port
flutter packages pub run test $1 --tags $2
在*nix中，我使用：
以这种方式运行测试可以让您在调试器中启动应用程序，并设置所有必要的断点，然后对该应用程序运行测试，这样您就可以检查正在运行的应用程序中的所有故障了是的……这就是我最后要做的。不过这很难看：
