Matan Lurey e517ae3457 Refactor android_engine_test, make it easier to debug/deflake locally. (#161534) ... The goal here is to have a great standalone `android_engine_test` suite that [replaces `scenario_app/android`](https://github.com/flutter/flutter/pull/160992). No test is _functionally_ changed in this PR, but overview of changes: - Finished renaming the suite `android_engine_tests` instead of `flutter_driver_android` - Added instructions and an environment variable for local generation of golden-files (`UPDATE_GOLDENS=1`) - Added explanations of the individual tests, where they live, and how to run them locally - Added a hybrid-composition (HC, not TLHC, which is already tested) test - Renamed "other_smiley" to "surface_texture_smiley" (and renamed the original to "surface_producer_smiley") - Removed unnecessary ".android" suffix (we will not run this on anything but Android) - Added a `tool/deflake.dart` to run a test suite 10x (or custom) times locally to try and determine flakiness After this PR, I'll add flags to let you control variants and name the screenshots accordingly, i.e.: - API v34 or v35 - OpenGLES or Vulkan (will require an `AndroidManifest.xml` edit during the test instrumentation)		2025-01-15 01:05:31 +00:00
