let中的phpspec标量值

我尝试使用带有标量值的let函数。 我的问题是价格是双倍的，我希望是整数5

function let(Buyable $buyable, $price, $discount)
{
    $buyable->getPrice()->willReturn($price);
    $this->beConstructedWith($buyable, $discount);
}

function it_returns_the_same_price_if_discount_is_zero($price = 5, $discount = 0) {
    $this->getDiscountPrice()->shouldReturn(5);
}

错误：

✘ it returns the same price if discount is zero
expected [integer:5], but got [obj:Double\stdClass\P14]

是否有办法使用let函数注入5？

将

5

转换为

（双）

：

或使用：

---

在PhpSpec中，在

let（）

、

letgo（）

或

it_*（）

方法的参数中出现的任何内容都是双重测试。它不应该与标量一起使用

PhpSpec使用反射从类型提示或

@param

注释获取类型。然后，它创建一个带有预言的假对象，并将其注入到一个方法中。如果找不到类型，它将创建一个假的

\stdClass

Double\stdClass\P14

与

Double

类型无关。这是一个好主意

您的规范可能如下所示：

private $price = 5;

function let(Buyable $buyable)
{
    $buyable->getPrice()->willReturn($this->price);

    $this->beConstructedWith($buyable, 0);
}

function it_returns_the_same_price_if_discount_is_zero() 
{
    $this->getDiscountPrice()->shouldReturn($this->price);
}

尽管我更愿意包括与当前示例相关的所有内容：

function let(Buyable $buyable)
{
    // default construction, for examples that don't care how the object is created
    $this->beConstructedWith($buyable, 0);
}

function it_returns_the_same_price_if_discount_is_zero(Buyable $buyable) 
{
    // this is repeated to indicate it's important for the example
    $this->beConstructedWith($buyable, 0);

    $buyable->getPrice()->willReturn(5);

    $this->getDiscountPrice()->shouldReturn(5);
}

---

这可以用于比较，但是我在getDiscountPrice函数中乘以返回值，所以它在getDiscountPrice函数中失败，而在测试中失败。在willReturn中铸造双精度也会失败。

private $price = 5;

function let(Buyable $buyable)
{
    $buyable->getPrice()->willReturn($this->price);

    $this->beConstructedWith($buyable, 0);
}

function it_returns_the_same_price_if_discount_is_zero() 
{
    $this->getDiscountPrice()->shouldReturn($this->price);
}

function let(Buyable $buyable)
{
    // default construction, for examples that don't care how the object is created
    $this->beConstructedWith($buyable, 0);
}

function it_returns_the_same_price_if_discount_is_zero(Buyable $buyable) 
{
    // this is repeated to indicate it's important for the example
    $this->beConstructedWith($buyable, 0);

    $buyable->getPrice()->willReturn(5);

    $this->getDiscountPrice()->shouldReturn(5);
}
