@dcharkes, I think this should work, but the tree is currently broken and the integration tests are currently failing for unrelated reason.

knopp · 2024-05-21T17:08:46Z

@dcharkes, it seems that the hot reload test (with the fix) passes successfully on simulator on CI:

21:26 +72 ~1: test/integration.shard/isolated/native_assets_test.dart: flutter run hot reload and hot restart with native assets 873FC224-4044-471E-9CFA-9739B82F3105 debug

dcharkes

Great!

Before merging, could you check the existing device lab test? That already spin up a simulator.

dcharkes · 2024-05-22T16:15:15Z

packages/flutter_tools/test/integration.shard/isolated/native_assets_test.dart

We have all this logic already in the device lab tests.

https://github.com/flutter/flutter/blob/e6fa8655819e9b92740911b49e8215efc6e52dab/dev/devicelab/bin/tasks/native_assets_ios_simulator.dart

$ cd <...>/flutter/dev/devicelab && dart bin/test_runner.dart test -t native_assets_ios_simulator

Would you be able to check why the existing hot integration test was not failing on the ios simulator?

(I don't feel strongly opposed to adding the logic also here, but since we already have it in the device lab tests it feels a bit like unnecessary code duplication.)

I think the problem is that when hot restart happens this is in the logs

Performing hot restart... Restarted application in 325ms. ══╡ EXCEPTION CAUGHT BY WIDGETS LIBRARY ╞═══════════════════════════════════════════════════════════ The following ArgumentError was thrown building _FocusInheritedScope:

The test only checks for Restarted application, which is there, so it assumes it passed, the exception is printed after. I think this is handled bit differently in the integration tests that's why those catch the issue.

This is present in the integration test

expect(stdout, isNot(contains('EXCEPTION CAUGHT BY WIDGETS LIBRARY')));

Probably should be added to device lab tool

But even if I detect the exception and return TaskResult.failure the task still exits with success for some reason.

@dcharkes, this should fix the device lab test: eb6b04c

Should I remove the simulator from integration tests?

I wouldn't mind having it there, it's easier to run locally than the devicelab test.

However, I believe we shouldn't be using infinite resources on CI. And the test coverage should be similar between the integration test with the simulator and the devicelab test with the simulator.

cc @jmagman @vashworth What's our policy on how much testing resources we use? And what's the policy on where simulator tests should run? (Integration suite vs device lab. I'm added the simulator to the device lab based on existing device lab tests that run the simulator.)

Thanks for diving into this @knopp! ❤️

The 4/4 shard already takes long time to complete (in fact it did timeout in previous run and I had to restart it). I think maybe it's a good idea to remove it.

Yeah that test runs long already. We don't want to introduce flakes due to timeouts. Let's remove it from this PR.

That means that this PR will just be a test fix and a fix 👍

dev/devicelab/bin/tasks/native_assets_ios_simulator.dart

Please also fix dev/devicelab/bin/tasks/native_assets_ios.dart

That one seems fine? I looked at it and it seems to propagate the result of createNativeAssetsTest correctly.

dcharkes

LGTM with simulator removed again from integration test.

I don't think it is related to this PR. I'm going to restart the test to see if it passes, but I think it might be flaky?
