host.takeScreenshot & host.runProcess (do not) time out

[creativecreatorormaybenot]

When running this code from the examples:

await $.host.runProcess(
  'bash',
  arguments: ['-c', 'echo "hello world" > hello.txt'],
);

Or this code:

await $.host.takeScreenshot(name: '1_before_run');

On macOS on an iOS simulator using patrol drive, the tests continue running forever.
That is the screenshot is never taken (no file is generated) and the host process is never executed (does not take action).

It seems that this line:

patrol/packages/patrol/lib/src/binding.dart

Line 161 in a7dfa43

final resp = await _controller.stream.firstWhere((r) => r.id == eventId);

Halts the tests forever. I did notice this comment:

patrol/packages/patrol/lib/src/host/host_automator.dart

Line 38 in a7dfa43

// TODO: Add timeout after 10 sec

However, the process is also never executed. So adding a timeout would not fix the underlying problem in my case.

Hi! Thanks for reporting this issue.

I've just run patrol drive -t integration_test/process_test.dart (in the example app) and it worked (patrol 0.10.6, patrol_cli v0.8.1).

I'm going to keep this open but I cannot reproduce this. I'd be happy if we had more info on this.

This feature is no longer available because of our massive architectural change in #661.

We plan to bring it back sometime in the future, but it won't be in our 1.0 release.
