scene_test 0.11.0

craft_runner builder that composes every `class X extends Scene` under test/ into a scene collection exposed on PatrolTester.

scene_test

A craft_runner builder that collects every scene page-object in your test suite into a collection on PatrolTester, so tests reach a scene through the $.scenes namespace instead of constructing it by hand.

await $.scenes.login.enterPhone('0910000000');
await $.scenes.login.submit();
await $.scenes.home.expectGreeting('Ahmed');

Setup

dev_dependencies:
  scene_test: ^0.11.0

Declare the builder in craft_runner.yaml:

roots: [test]

builders:
  scene_test:SceneCraftBuilder:

Then run craft_runner craft, or craft_runner watch to regenerate on save.

Writing a scene

A scene is a class extending Scene, in a file ending _scene.dart. Scene is yours to define — the builder only matches on the name:

// test/core/scene.dart
abstract class Scene {
  late PatrolTester $;
}

// test/features/login/login_scene.dart
class LoginScene extends Scene {
  Future<void> enterPhone(String phone) => $(#phoneField).enterText(phone);
  Future<void> submit() => $(#submitButton).tap();
}

The builder finds it and writes test/core/scenes.craft.dart:

extension PatrolTesterExtension on PatrolTester {
  PatrolScenes get scenes => PatrolScenes(this);
}

final class PatrolScenes {
  PatrolScenes(this.$);

  final PatrolTester $;

  LoginScene get login => LoginScene()..$ = $;
}

Naming

The getter in $.scenes is the class name with a lowercased first letter and a trailing Scene stripped — so HomeWalletScene becomes homeWallet. Imports are emitted relative to the output file and sorted, and scenes are ordered by class name, so the generated file is stable across runs.

Requirements and limits

• Only *_scene.dart files are scanned. A scene in login_page.dart is silently ignored.
• The superclass must be written literally as Scene. Matching is syntactic (craft_runner never resolves types), so an aliased import or an intermediate base class won't be detected.
• The output path is fixed at test/core/scenes.craft.dart.
• patrol_finders is not a dependency of this package — it only appears in the generated import, so your project supplies it.
