函数测试验证器：与其他属性进行比较

Question

基于示例 sillthan.htthan.html为我自己的验证器@ASSERT \量编写功能调查。 $金额应根据$货币进行验证。

我的问题是，如何在函数测试中设置$货币的值？我已经查看了包装符号/验证器的测试，但找不到线索。我已经为验证器编写了函数测试。但是我没有任何要求。

有人可以给我提示还是向我展示一个例子。

例子：

class Entity
{
     /**
     * @var \string
     * @Assert\Currency()
     */
    protected $currency;

     /**
     * @var \float
     * @Assert\Amount(propertyPath="currency")
     */
    protected $amount;
}

Answer 1

我找到了解决方案。我验证了完整的实体，并查看了验证器中的对象，并找到了完整的实体。

当我考虑如何测试时，我进行了一些研究，并发现了其他相同的测试。我不知道这是否是最好的解决方案，但是我现在可以编写测试。

CondectValidatTestCase

<?php
    
namespace App\Tests\Validator\Constraint;

use App\Entity\Entity;
use App\Validator\MinimumAmount;
use App\Validator\MinimumAmountValidator;
use Symfony\Component\Validator\Context\ExecutionContext;
use Symfony\Component\Validator\Test\ConstraintValidatorTestCase;
use Symfony\Component\Validator\Validator\ValidatorInterface;
use Symfony\Contracts\Translation\TranslatorInterface;
use Symfony\Component\Validator\Context\ExecutionContextInterface;
use Symfony\Component\Validator\ConstraintValidatorInterface;

class MinimumAmountValidatorTest extends ConstraintValidatorTestCase
{
   /**
   * @var ExecutionContextInterface
   */
   protected $context;

    /**
    * @var ConstraintValidatorInterface
    */
    protected $validator;

    /**
    * @var Constraint
    */
    protected $constraint;

    protected function setUp(): void
    {
        $this->constraint = new Entity();
        $this->context = $this->createContext();
        $this->validator = $this->createValidator();
        $this->validator->initialize($this->context);
    }

    public function createValidator(): MinimumAmountValidator
    {
        return new MinimumAmountValidator();
    }

    public function createContext(): ExecutionContext
    {
        $myEntity = new Entity();
        $myEntity->setCurrency('EUR');

        $translator = $this->createMock(TranslatorInterface::class);
        $translator->expects($this->any())->method('trans')->willReturnArgument(0);
        $validator = $this->createMock(ValidatorInterface::class);

        $executionContext = new ExecutionContext($validator, $myEntity, $translator);
        $context->setNode('InvalidValue', null, null, 'property.path');
        $context->setConstraint($this->constraint);
        return $executionContext;
    }


    public function testValidation()
    {
        $this->validator->validate(40.00, new  MinimumAmount());
        $this->assertNoViolation();
    }
}
 

约束

<?php

namespace App\Validator;

use Symfony\Component\Validator\Constraint;

/**
 * @Annotation
 */
class MinimumAmount extends Constraint
{
    /**
     * @var string
     */
    public $message = '';

    /**
     * @return string
     */
    public function validatedBy(): string
    {
        return MinimumAmountValidator::class;
    }
}

验证器

<?php

namespace App\Validator;

use App\Entity\Entity;
use Symfony\Component\Validator\Constraint;
use Symfony\Component\Validator\ConstraintValidator;

class MinimumAmountValidator extends ConstraintValidator
{
    /**
     * @param float $value
     * @param Constraint $constraint
     *
     * @return void
     */
    public function validate($value, Constraint $constraint)
    {
        /**
         * @var Entity
         */
        $contextRoot = $this->context->getRoot();
        $currency = $contextRoot->getCurrency(); // EUR
        $amount = $value; // 40.00

        // Validation implementation

    }
}
