单元测试自定义验证器

Question

我的验证器看起来像：

<?php

declare(strict_types=1);

namespace App\Infrastructure\Domain\Model\Company\Validator;

use Symfony\Component\Validator\Constraint;
use Symfony\Component\Validator\ConstraintValidator;
use Symfony\Component\Validator\Exception\UnexpectedTypeException;
use Symfony\Component\Validator\Exception\UnexpectedValueException;
use Symfony\Contracts\Translation\TranslatorInterface;

final class ContainsUnsupportedSymbolsValidator extends ConstraintValidator
{
    public function __construct(
        private TranslatorInterface $translator
    )
    {
    }

    public function validate($value, Constraint $constraint): void
    {
        if (!$constraint instanceof ContainsUnsupportedSymbols) {
            throw new UnexpectedTypeException($constraint, ContainsUnsupportedSymbols::class);
        }

        // custom constraints should ignore null and empty values to allow
        // other constraints (NotBlank, NotNull, etc.) to take care of that
        if (null === $value || '' === $value) {
            return;
        }

        if (!is_string($value)) {
            // throw this exception if your validator cannot handle the passed type so that it can be marked as invalid
            throw new UnexpectedValueException($value, 'string');
        }

        if (!preg_match('/^\+?[0-9]{3}-?[0-9]{6,12}$/', $value, $matches)) {
            // the argument must be a string or an object implementing __toString()
            $this->context->buildViolation(
                $this->translator->trans($constraint->message, ['{phone}' => $value])
            )->addViolation();
        }
    }
}

我为有效案例编写的测试是：

<?php

declare(strict_types=1);

namespace App\Tests\Unit\Infrastructure\Domain\Model\Company\Validator;

use App\Infrastructure\Domain\Model\Company\Validator\ContainsUnsupportedSymbols;
use App\Infrastructure\Domain\Model\Company\Validator\ContainsUnsupportedSymbolsValidator;
use App\Tests\Unit\UnitTestCase;
use Symfony\Component\Validator\Context\ExecutionContextInterface;
use Symfony\Contracts\Translation\TranslatorInterface;

final class ContainsUnsupportedSymbolsValidatorTest extends UnitTestCase
{
    public function testValidatorWithValidPhone():void
    {
        $phone = "+359883202020";

        $translationMock = $this->createMock(TranslatorInterface::class);

        $constraint = new ContainsUnsupportedSymbols();

        $constraintValidator = new ContainsUnsupportedSymbolsValidator($translationMock);

        $this->assertEmpty($constraintValidator->validate($phone, $constraint));
    }
}

使用 assementy 测试是否正确。 ？ 以及如何使用错误的数据测试？试图模拟上下文和 buildviolation 和 addviolation 方法，但有错误：

错误：在null上致电成员函数buildviolation（）

这是我尝试使用不正确的电话

public function testValidatorWithInvalidPhone():void
    {
        $phone = "+359()883202020";

        $translationMock = $this->createMock(TranslatorInterface::class);

        $contextMock = $this->createMock(ExecutionContextInterface::class);
        $contextMock->expects($this->once())
            ->method('buildViolation')
            ->with('message');
        $contextMock->expects($this->once())
            ->method('addViolation');

        $constraint = new ContainsUnsupportedSymbols();

        $constraintValidator = new ContainsUnsupportedSymbolsValidator($translationMock);

        $this->assertEmpty($constraintValidator->validate($phone, $constraint));
    }

您的上下文是无效的。您必须初始化由自定义验证器扩展的 CondraintValidator 。
这个问题在这里找到了一个答案：单位测试自定义符号约束

简短这是一个示例

在示例中，测试类扩展了 consect> CODE> CONDER> CONDER> CONDERTVALIDATETTESTESTCASE 上下文（在这里查看：）
