High flake rate on test/integration.shard/debug_adapter/flutter_adapter_test.dart #120015
Description
Causing many framework tree failures over the past 18 hours and regularly blocking the engine roll.
Example build failure: https://ci.chromium.org/ui/p/flutter/builders/prod/Mac%20tool_integration_tests_3_4/8690/overview
10:54 +35 ~3: test/integration.shard/debug_adapter/flutter_adapter_test.dart: launch can run and terminate a Flutter app in debug mode
10:54 +35 ~3 -1: test/integration.shard/debug_adapter/flutter_adapter_test.dart: launch can run and terminate a Flutter app in debug mode [E]
Expected: [
'Launching lib/main.dart on Flutter test device in debug mode...',
<a string starting with 'Connecting to VM Service at'>,
'topLevelFunction',
'Application finished.',
'',
<a string starting with 'Exited'>
]
Actual: [
'Resolving dependencies...',
'Got dependencies!',
'Launching lib/main.dart on Flutter test device in debug mode...',
'Connecting to VM Service at ws://127.0.0.1:52181/HQp8g3KSTmo=/ws',
'topLevelFunction',
'Application finished.',
'',
'Exited.'
]
Which: at location [0] is 'Resolving dependencies...' instead of 'Launching lib/main.dart on Flutter test device in debug mode...'
