如何使用PHPSpec测试创建项目的类

Question

我上课主要是为了这个

$newItem = new SeriesDiscountDecorator($item);
$cart->remove($item);
$cart->add($newItem);

我的规格看起来像

$decoratedItem1->beConstructedWith([$item1]);
$cart->add($decoratedItem1)->shouldBeCalled();

但PHPSpec表示由于参数错误而无法进行$ cart-＆gt;添加调用。实际上我的$ decoratedItem与Cart类所做的不同。如何写这样的规格吧？

PHPSpec返回：

method call:
    - add(Domain\Discount\Decorator\SeriesDiscountDecorator:000000006b0917e60000000063743658 Object (
        'decoratedItem' => Double\ItemInterface\P66:000000006b0917a60000000063743658 Object (
        'objectProphecy' => Prophecy\Prophecy\ObjectProphecy Object (*Prophecy*)
          )
      ))
    on Double\Domain\Cart\Cart\P65 was not expected, expected calls were:
        - add(exact(Double\Domain\Discount\Decorator\SeriesDiscountDecorator\P69:000000006b0917f90000000063743658 Object (
        'objectProphecy' => Prophecy\Prophecy\ObjectProphecy Object (*Prophecy*)
              'decoratedItem' => PhpSpec\Wrapper\Collaborator:000000006b0917b30000000063743658 Object (
        'prophecy' => Prophecy\Prophecy\ObjectProphecy Object (*Prophecy*)
              )
        )))

Answer 1

$cart->add(SeriesDiscountDecorator::class)->shouldBeCalled();

似乎是测试它的唯一方法，只要你在实例化你所指定的类中的对象并且你没有返回它。
