Sample usage: To run only the embedder_unittests in the engine with the profile variant, the command would be ``` ./flutter/testing/run_tests.py --variant host_profile_unopt --type engine --filter embedder_unittests `` To run only the geometry in Dart with the debug variant, the command would be ``` ./flutter/testing/run_tests.py --variant host_debug_unopt --type dart --filter geometry_test `` Without any argument, the behavior is identical to `run_tests.sh`. In a subsequent patch, I will enable running unit-tests on Windows in the tryjobs. The lack of compatibility of the shell script on Windows made it so that we never ran any Windows unit-tests in the tryjobs.
Flutter Engine
Flutter is Google's mobile app SDK for crafting high-quality native interfaces on iOS and Android in record time. Flutter works with existing code, is used by developers and organizations around the world, and is free and open source.
The Flutter Engine is a portable runtime for hosting Flutter applications. It implements Flutter's core libraries, including animation and graphics, file and network I/O, accessibility support, plugin architecture, and a Dart runtime and compile toolchain. Most developers will interact with Flutter via the Flutter Framework, which provides a modern, reactive framework, and a rich set of platform, layout and foundation widgets.
If you are new to Flutter, then you will find more general information on the Flutter project, including tutorials and samples, on our Web site at Flutter.dev. For specific information about Flutter's APIs, consider our API reference which can be found at the docs.flutter.dev.
Flutter is a fully open source project, and we welcome contributions. Information on how to get started can be found at our contributor guide.
