【问题描述】：

首先，我现在的环境：

Docker 版本 20.10.1
docker-compose 版本 1.27.4
MySql 8.0.21（Docker 镜像）
PHP 7.4.13 - Docker 映像
PHP 7.4.13 本地

作曲家.json：

"require": {
    "php": "^7.4|^8.0",
    "doctrine/dbal": "^3.0",
    "fideloper/proxy": "^4.4",
    "fruitcake/laravel-cors": "^2.0",
    "guzzlehttp/guzzle": "7.0",
    "laravel-lang/lang": "~8.0",
    "laravel/framework": "^8.12",
    "laravel/tinker": "^2.5",
    "ramsey/uuid": "^4.1"
},
"require-dev": {
    "barryvdh/laravel-ide-helper": "^2.9",
    "facade/ignition": "^2.5",
    "fakerphp/faker": "^1.9.1",
    "laravel/breeze": "^1.0",
    "mockery/mockery": "^1.4.2",
    "nunomaduro/collision": "^5.0",
    "phpunit/phpunit": "^9.3.3"
}

我在运行时收到以下错误：

$ php 工匠测试

PHP Fatal error:  Uncaught Illuminate\Contracts\Container\BindingResolutionException: 
Target [Illuminate\Contracts\Debug\ExceptionHandler] is not instantiable. 
in /home/______/proj/php//______/vendor/laravel/framework/src/Illuminate/Container/Container.php:1038

我的测试文件（我的测试还没写完）：

<?php

namespace Tests\Unit;

use App\Models\Pessoa;
use Illuminate\Foundation\Testing\RefreshDatabase;
use Tests\TestCase;

class __________ extends TestCase
{
    use RefreshDatabase;
    protected Pessoa $pessoa;
    /**
     * A basic unit test example.
     *
     * @return void
     */
    public function testExample()
    {
        $this->pessoa = factory(Pessoa::class);

        $this->assertTrue(true);
    }
}

【解决方案1】：

嗯，“解决方案”有点简单，在搜索了很多之前，我在GitHub issues上找到了以下语句：

“对我来说，它原来是访问权限。这可能是 vm/container 环境的问题。”

我尝试使用 SU 运行它，但又遇到了另一个错误：

$ sudo php 工匠测试

嗯，它也不起作用，但是因为我是使用 docker 在本地运行这个项目，所以我尝试在 Container 中运行它，它起作用了！

$ docker exec f546517976f4 php artisan test

TL;DR : 在 Docker 容器中运行测试
