Laravel 10+PHPUnit 10单测报错：Cannot find TestCase object on call stack

问题现象 #

• 执行php artisan test运行全部测试时，所有测试均可正常执行；
• 执行php artisan test --filter test_get_profile单独运行指定测试方法时，触发PHPUnit内部错误：

  An error occurred inside PHPUnit.
  
  Message:  Cannot find TestCase object on call stack
  Location: D:\laragon\www\project\vendor\phpunit\phpunit\src\TextUI\TestRunner.php:68
  

• 部分测试方法（如test_login、test_register）可单独正常运行，但新建测试方法时偶尔会出现上述错误；
• 若指定测试文件路径执行php artisan test tests/Feature/AccountTest.php --filter test_get_profile则无报错，但希望无需每次指定路径。

测试代码示例 #

所有测试方法均为基础空测试，示例如下：

public function test_get_profile(): void
{
    $response = $this->get('/');

    $response->assertStatus(200);
}

相关配置与测试文件代码 #

请问有人知道该问题的原因吗？
