这应该非常简单，但今天下午它让我发疯，对自定义 symfony 验证器进行单元测试的正确方法是什么？我能找到的所有文章都与我的做法完全相同

class Foo extends Constraint
{
    public string $message = 'The string "{{ string }}" is not a valid foo.';
}

class FooValidator extends ConstraintValidator
{
    /**
     * {@inheritdoc}
     */
    public function validate($value, Constraint $constraint): void
    {
        if ($value !== 'foo') {
            $this->context->buildViolation($constraint->message)
                ->setParameter('{{ string }}', $value)
                ->addViolation();
        }
    }
}

class FooValidatorTest extends TestCase
{

    /** @test  */
    public function validate(): void
    {
        $this->expectNotToPerformAssertions();

        $constraint = new Foo();
        $context    = \Mockery::mock(ExecutionContextInterface::class);
        $builder    = \Mockery::mock(ConstraintViolationBuilderInterface::class);

        $context->shouldReceive('buildViolation')
            ->with($constraint->message)
            ->andReturn($this->builder); …
