TestDirector<Unit, Args> class

A class that combines ArgsBuilder and UnitBuilder to provide a flexible and reusable way to set up and construct test scenarios.

TestDirector is designed to be extended or used directly in test files to create organized and maintainable test setups, especially for Flutter widget tests.

The Unit type parameter typically represents the widget or object being tested, while Args represents the arguments used to construct the unit.

Usage:

class MyUnitTestDirector extends TestDirector<MyClass, String> {
  MyUnitTestDirector() {
    setUnitFactory((args) => MyClass(value: args));
  }
}

void main() {
  late MyUnitTestDirector director;

  setUp(() {
    director = MyUnitTestDirector();
  });

  test('MyClass behaves correctly', () {
    director.setArgs('test value');
    final myObject = director.construct();
    expect(myObject.value, equals('test value'));
  });
}
