问题描述
使用 Flutter integration_test 包时，我遇到了一个由于无法从测试环境访问的 iOS 权限请求而不断失败的测试的问题。
我尝试了 github.com/wix/AppleSimulatorUtils 中的 applesimutils，但是在 Flutter Drive 之前尝试设置权限时，应用程序的包标识符尚未注册：
Got error:
An error was encountered processing the command (domain=NSPOSIXErrorDomain,code=2):
The operation Couldn’t be completed. No such file or directory
No such file or directory
也许这可以通过不每次都创建一个新的 Simulator 实例来避免，但是我通过在 Flutter drive ... & sleep 10 命令之前运行 applesimutils --setPermissions 以允许应用程序首先启动来解决这个问题，但这仍然给出我：
══╡ EXCEPTION CAUGHT BY FlutteR TEST FRAMEWORK ╞═════════════════
The following LocationError object was thrown running a test:
[LocationError code: 0,message: null]
When the exception was thrown,this was the stack:
#2 BackgroundGeolocation.getCurrentPosition.<anonymous closure>
(package:Flutter_background_geolocation/models/background_geolocation.dart:497:17)
...
解决方法
更熟悉 xcrun simctl 后，我注意到它可以在应用程序启动之前授予权限，只要设备已启动。 applesimutils 不需要！
我的 shell 脚本形式的工作解决方案如下所示：
# Simulator setup
xcrun simctl create iOS14Simulator
xcrun simctl boot iOS14Simulator
xcrun simctl privacy iOS14Simulator grant location-always <YOUR_BUNDLE_ID>
# Launch integration test
flutter drive \
--driver=test_driver/integration_test_driver.dart \
--target=integration_test/app_test.dart
# Simulator teardown
xcrun simctl delete iOS14Simulator
