Failed tests for initial land:
https://flutter-dashboard.appspot.com/#/build?hashFilter=5ca6350a06fdae8d3e160f9adbece193f34d0302&repo=flutter&branch=master
These two tests run the same `flavors_test`

https://ci.chromium.org/ui/p/flutter/builders/prod/Windows_mokey%20flavors_test_win/988/overview
which is now passing
https://ci.chromium.org/ui/p/flutter/builders/try/Linux_pixel_7pro%20flavors_test/37/overview
(fixed by 23c62df1dc)
The other failures seem to be flakes

the first is a timeout, the second passed in presubmit on the original PR and also on this PR.
external_textures
Tests external texture rendering between a native1 platform and Flutter.
Part of Flutter's API for plugins includes passing external textures, or textures
created outside of Flutter, to Flutter, typically using the Texture
widget. This is useful for plugins that render video, or for plugins that
interact with the camera.
For example:
Because external textures are created outside of Flutter, there is often subtle translation that needs to happen between the native platform and Flutter, which is hard to observe. These integration tests are designed to help catch these subtle translation issues.
How it works
- Each
lib/*_main.dartfile is a Flutter app instrumenting a test case. - There is a corresponding
test_driver/*_test.dartthat runs assertions.
To run the test cases locally, use flutter drive2:
flutter drive lib/frame_rate_main.dart --driver test_driver/frame_rate_test.dart
Tip
On CI, the test cases are run within our device lab.
See
devicelab/lib/tasks/integration_tests.dartand search forcreateExternalUiFrameRateIntegrationTest.The actual tests are run by task runners:
