unit-testing - 对多关系的意外不可迭代值

Question

当我运行 phpunit 时，

$this->assertResponseIsSuccessful();

显示错误：

'hydra:description' => 'Unexpected non-iterable value for to-many relation'

Failed asserting that the Response is successful.
HTTP/1.1 400 Bad Request
Cache-Control:          no-cache, private

X-Frame-Options:        deny

我认为这个问题与实体中的空值有关。

    /**
     * @return Collection|null<int, Falta>
     */
    public function getFalta(): ?Collection
    {
        return $this->falta;
    }

这说得通？以及如何解决这个问题？

Answer 1

您遇到错误，因为Collection(ArrayCollection) 未初始化。

将构造函数添加到您的实体并将每个集合值设置为new ArrayCollection();

它应该看起来像：

use Doctrine\Common\Collections\ArrayCollection;

public function __construct()
{
    $this->ordemServicoContratoItemPessoa = new ArrayCollection();
    $this->falta = new ArrayCollection();
}
