unit-testing - 一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' => '一对多关系出现意外的不可迭代值'

Failed asserting that the Response is successful.
HTTP/1.1 400 Bad Request

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;
    }

有道理吗？如何解决这个问题？

Answer 1

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

向您的实体添加一个构造函数，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();
}
