mysql DB 上的 PDOException：并行测试时“已经存在活动事务” 说明：

如何解决mysql DB 上的 PDOException：并行测试时“已经存在活动事务” 说明：

• Laravel 版本：8.33.1
• PHP 版本：8.0.3
• 数据库驱动程序和版本：MySQL 5.7.32

说明：

您好，我们想测试多个数据库交互，所以我们需要独立的测试和一种方法来创建/迁移/种子我们的 mysql 数据库（磁盘存储）副本。我们正在使用 Sanctum 进行身份验证。

我一直在尝试使用新的并行测试功能并阅读您的不同文档和相关问题。

我的结论是：

• 需要 DatabaseTransactions 特性，其他特性全部或部分被 ParallelTesting“替换”
• 新的 ParallelTesting::setUpTestDatabase() 正是我在创建数据库时需要的内容
• 不需要测试数据库定义，因为 ParallelTesting 已经创建了 name_test_1、name_test_2 形式的副本
• 如果没有 --recreate-databases，则不会再次调用播种，因为它仅在创建其测试数据库后调用

我的种子是一堆工厂，DB::unprepared。

手动运行 art migrate:fresh 和 art db:seed，然后在没有 art test 的情况下运行 --parallel，测试工作正常。但是，当使用 --parallel --recreate-databases 运行时，播种不起作用，我偶然发现了这个错误：

PDOException: 已经有一个活动事务
