Opening deep link in integration test in Flutter - flutter

Question

I'm trying to run an integration test which is highly dependent on the user clicking a magic link he got in his email. So far I failed to find a way of doing that. I came across Process.run but it seems like it should be run before the integration test starts and I need to do it during the test.
Any help with either iOS or Android will be highly appreciated. 🙏
This is the code I tried so far to work on iOS but Process.run ends with ProcessException: No such file or directory:
void main() {
IntegrationTestWidgetsFlutterBinding.ensureInitialized();
testWidgets('login test', (WidgetTester tester) async {
app_sandbox.main();
await tester.pumpAndSettle(Duration(seconds: 5));
expect(find.text('foo'), findsOneWidget);
await Process.run('xcrun', [
'simctl',
'openurl',
'7D6DEC47-C1E2-4F18-A38B-7B4C17558172',
'https://myDeepLink/sign-in',
]);
await tester.pumpAndSettle();
});
}

Answer 1

this might only work with flutter_driver
await Process.run('xcrun', [
'simctl',
'openurl',
'booted',
'https://myDeepLink/sign-in'
]).then((result) {
stdout.write(result.stdout);
stderr.write(result.stderr);
});
not with testWidgets of integration_test
there I got this error:
