PHP spec - 特定类型的数组

Question

在phpspec中,如何测试类属性是否包含特定类型的数组？

例如:

class MyClass
{
   private $_mySpecialTypes = array();

   // Constructor ommitted which sets the mySpecialTypes value

   public function getMySpecialTypes()
   {
      return $this->_mySpecialTypes;
   }
}

我的规格看起来像这样:

public function it_should_have_an_array_of_myspecialtypes()
{
    $this->getMySpecialTypes()->shouldBeArray();
}

但我想确保数组中的每个元素都是类型 MySpecialType

什么是在phpspec中做到这一点的最好方法？

您可以使用内联匹配器:

namespace spec;

use PhpSpec\ObjectBehavior;
use Prophecy\Argument;

use MySpecialType;

class MyArraySpec extends ObjectBehavior
{
    function it_should_have_an_array_of_myspecialtypes()
    {
        $this->getMySpecialTypes()->shouldReturnArrayOfSpecialTypes();
    }

    function getMatchers()
    {
        return array(
            'returnArrayOfSpecialTypes' => function($mySpecialTypes) {
                foreach ($mySpecialTypes as $element) {
                    if (!$element instanceof MySpecialType) {
                        return false;
                    }
                }
                return true;
            }
        );
    }
}
