Help to run the Patrol examples

[cristianorsilva]

Hi!

I have tried to use Patrol in my projects, then I followed the instructions here (https://patrol.leancode.co/native/overview). However in all of them I got the error below:

'package:flutter/src/foundation/binding.dart': Failed assertion: line 149 pos 12: '_debugInitializedType == null': is not true.

I suspected that I was missing something in my projects, then I decided to run the patrol examples (https://github.com/leancodepl/patrol/tree/master/packages/patrol/example) but to my surprise, I got the same error:

Failed to load "/Users/cristiano/Downloads/patrol/patrol-master/packages/patrol/example/integration_test/open_app_test.dart": 'package:flutter/src/foundation/binding.dart': Failed assertion: line 149 pos 12: '_debugInitializedType == null': is not true.

Am I missing some config in my setup? Any ideas about what is happening?

Thanks in advance!

Hi! What command are you executing to run the tests?

Make sure to use patrol test.

[cristianorsilva]

Hi! You got it!!! My mistake was trying to run only by the left green icon on the test, but when I ran the command 'patrol test --target integration_test/android_app_test.dart' it worked perfectly :)

Patrol examples working here. Now I will fix my ones, got some errors but I think I can handle :)

Thanks!!!
