flutter start's method of finding devices to run the app on is not suitable for flutter drive.
This commit also refactors several tool services to allow mocking in unit tests.
Now that we don't require the Dart SDK to be in your path, it's hard to run
./dev/update_packages.dart. Instead, you can now run `flutter update-packages`.
Fixes#1906
Migrates error suppression from regexps to analysis options.
* Ignore TODOs.
* Ignore strong mode field and method overrides (see `InvalidFieldOverride` and `InvalidMethodOverride` in `strong/info.dart`.
* Remove stale regexp to capture refs to dead `dart:ui_internals` URI.
* Remove stale regexp to capture dead strong mode "will need runtime check to cast to type" error (https://github.com/dart-lang/sdk/issues/24542).
5 regexp downs, another small handful (~4) to go! :)
This enables us to exclude `library_names` pending a new stable SDK push (see notes: https://github.com/flutter/flutter/pull/1996). Also excluded are a few lints who's feedback was just getting regexp'ed out. Moving forward, this will allow us to selectively enable specific lints of interest as well.
"flutter create" adds option `--with-driver-test` that adds
dependencies to `flutter_driver` in `pubspec.yaml` and creates
a basic driver test runnable via `flutter drive
--target=test_driver/e2e.dart`
"flutter drive" new options:
- `--keep-app-running` tells the driver to not stop the app after tests
are done
- `--use-existing-app` tells the driver to not start a new app but use
an already running instance
Downloading these packages from cloud storage simplifies our deployment
story because we can upload to cloud storage automatically from the
buildbot.
This patch also switches the responsibility for downloading the engine
artifacts to update_engine.sh. Centralizing this responsibility ensures
that the packages and the binaries are always in sync.
Runs a test app and a driver test simultaneously, then stops the app.
Usage:
```
flutter drive --target=/path/to/test/app.dart
```
This command will look for `/path/to/test/app_test.dart` by
convention. We will expand into other ways of discovering tests in the
future.
