The EvaluatorBuilder build an Evaluator after configuring a few options.
$builder = new EvaluatorBuilder();
// allows you to add a custom adapter
$builder->registerAdapter($customAdapter);
// the default is "en_US"
$builder->withCulture('fr_FR');
// the default is "App\\Foundry\\Factory"
$builder->withFactoryNamespace('Your\Custom\Namespace');
// the default is created using InflectorFactory::create()->build()
$builder->withInflector($inflector);
$evaluator = $builder->build();
You may return to the README or read the behat, the evaluator or the adapters guides.
