受保护的属性 PHP Laravel

Question

如何在编写测试时访问受保护的 object PHP 的属性。 下面是我的示例代码。 TestCase.php 测试未能运行，表明该属性受到保护。 但它可能会死掉。

<?php

namespace Tests;

use Illuminate\Http\Response;
use Illuminate\Foundation\Testing\TestCase as BaseTestCase;

abstract class TestCase extends BaseTestCase
{
    use CreatesApplication;

    public function getAuthUser()
    {
        $payload = [
            'email' => 'admin@gamil.nl',
            'password' => 'password',
        ];
       return $this->json('post', 'api/v1/auth/login', $payload)
             ->assertStatus(Response::HTTP_OK);
    }
}

我的样本测试

<?php

namespace Tests\Unit;

use Tests\TestCase;
use Illuminate\Http\Response;

class PatientsControllerTest extends TestCase
{
    /**
     * A basic unit test patient controller.
     *
     * @return void
     */
    public function testPatientFetch()
    {
        $auth_user =  $this->getAuthUser();
        dd($auth_user->data);
    }
}

我的示例代码

<?php

namespace Tests\Unit;

use Tests\TestCase;
use Illuminate\Http\Response;

class PatientsControllerTest extends TestCase
{
    /**
     * A basic unit test patient controller.
     *
     * @return void
     */
    public function testPatientFetch()
    {
        $auth_user =  $this->getAuthUser();
        dd($auth_user->data);
    }
}

收到错误

       FAIL  Tests\Unit\PatientsControllerTest
  ⨯ patient fetch

Answer 1

为 $data 创建吸气剂 function

public function get_data(){
   return $this->data;
}

单元测试来测试功能而不是属性

Answer 2

您可以使用 ReflectionClass 访问和操作受保护的变量。

请试试这个：

$user = $this->getAuthUser();
$reflectionClass = new ReflectionClass($user);
//If we assume we have a protected variable $data we can get access it with Reflection Class
$property = $reflectionClass->getProperty('data');
$property->setAccessible(true); //Here we are making protected variables accessible
$property->setValue($user, 'New Protected Data');
