在测试Symfony控制器时模拟原理参数转换器

use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpKernel\Controller\ArgumentResolver;
use Symfony\Component\HttpKernel\ControllerMetadata\ArgumentMetadataFactory;
use Symfony\Component\HttpKernel\Controller\ArgumentResolver\RequestAttributeValueResolver;
use Symfony\Component\HttpKernel\Controller\ArgumentResolver\RequestValueResolver;
use Symfony\Component\HttpKernel\Controller\ArgumentResolver\DefaultValueResolver;
use Symfony\Component\HttpKernel\Controller\ArgumentResolver\VariadicValueResolver;

class MyControllerTest extends \PHPUnit\Framework\TestCase
{
    public function testMyController()
    {
        // 创建一个模拟的Request对象
        $request = Request::create('/my-controller', 'GET', ['param1' => 'value1']);

        // 创建一个参数转换器
        $argumentResolver = new ArgumentResolver(
            new ArgumentMetadataFactory(),
            [
                new RequestAttributeValueResolver(),
                new RequestValueResolver(),
                new DefaultValueResolver(),
                new VariadicValueResolver(),
            ]
        );

        // 模拟参数转换器将请求中的参数转换为控制器方法的参数
        $arguments = $argumentResolver->getArguments($request, 'MyController::myAction');

        // 断言控制器方法的参数是否正确
        $this->assertEquals(['value1'], $arguments);
    }
}
