* Adds support for `flutter test --wasm`. * The test compilation flow is a bit different now, so that it supports compilers other than DDC. Specifically, when we run a set of unit tests, we generate a "switchboard" main function that imports each unit test and runs the main function for a specific one based off of a value set by the JS bootstrapping code. This way, there is one compile step and the same compile output is invoked for each unit test file. * Also, removes all references to `dart:html` from flutter/flutter. * Adds CI steps for running the framework unit tests with dart2wasm+skwasm * These steps are marked as `bringup: true`, so we don't know what kind of failures they will result in. Any failures they have will not block the tree at all yet while we're still in `bringup: true`. Once this PR is merged, I plan on looking at any failures and either fixing them or disabling them so we can get these CI steps running on presubmit. This fixes https://github.com/flutter/flutter/issues/126692

/// Testing library for flutter, built on top of `package:test`.
|
|
///
|
|
/// ## Test Configuration
|
|
///
|
|
/// The testing library exposes a few constructs by which projects may configure
|
|
/// their tests.
|
|
///
|
|
/// ### Per test or per file
|
|
///
|
|
/// Due to its use of `package:test` as a foundation, the testing library
|
|
/// allows for tests to be initialized using the existing constructs found in
|
|
/// `package:test`. These include the [setUp] and [setUpAll] methods.
|
|
///
|
|
/// ### Per directory hierarchy
|
|
///
|
|
/// In addition to the constructs provided by `package:test`, this library
|
|
/// supports the configuration of tests at the directory level.
|
|
///
|
|
/// Before a test file is executed, the Flutter test framework will scan up the
|
|
/// directory hierarchy, starting from the directory in which the test file
|
|
/// resides, looking for a file named `flutter_test_config.dart`. If it finds
|
|
/// such a configuration file, the file will be assumed to have a `main` method
|
|
/// with the following signature:
|
|
///
|
|
/// ```dart
|
|
/// Future<void> testExecutable(FutureOr<void> Function() testMain) async { }
|
|
/// ```
|
|
///
|
|
/// The test framework will execute that method and pass it the `main()` method
|
|
/// of the test. It is then the responsibility of the configuration file's
|
|
/// `main()` method to invoke the test's `main()` method.
|
|
///
|
|
/// After the test framework finds a configuration file, it will stop scanning
|
|
/// the directory hierarchy. In other words, the test configuration file that
|
|
/// lives closest to the test file will be selected, and all other test
|
|
/// configuration files will be ignored. Likewise, it will stop scanning the
|
|
/// directory hierarchy when it finds a `pubspec.yaml`, since that signals the
|
|
/// root of the project.
|
|
///
|
|
/// If no configuration file is located, the test will be executed like normal.
|
|
///
|
|
/// See also:
|
|
///
|
|
/// * [WidgetController.hitTestWarningShouldBeFatal], which can be set
|
|
/// in a `flutter_test_config.dart` file to turn warnings printed by
|
|
/// [WidgetTester.tap] and similar APIs into fatal errors.
|
|
/// * [debugCheckIntrinsicSizes], which can be set in a
|
|
/// `flutter_test_config.dart` file to enable deeper [RenderBox]
|
|
/// tests of the intrinsic APIs automatically while laying out widgets.
