UnitBuilder<Unit, Args> mixin

A mixin that provides functionality for building and arranging units in test scenarios.

This mixin is typically used in conjunction with TestDirector to create flexible and reusable test setups for Flutter widgets and other units.

The Unit type parameter represents the type of object being built (e.g., a Widget), while Args represents the type of arguments used to construct the unit.

Usage:

class MyTestDirector extends TestDirector<Widget, String> {
  MyTestDirector() {
    setUnitFactory((args) => MyWidget(text: args));
    addUnitArrangement((widget) => Container(child: widget));
  }
}
