Laravel DatabaseTransactions

Question

我有一個很奇怪的問題。我試圖用phpunit在我的api中測試以下函數。

use DatabaseTransactions; 
    public $url = 'test.dev'; 

    /** @test */ 
    function show_school_stagiair_authorized() 
    { 
     factory(Company::class,1) 
      ->create(['CompanyId' => 1]); 
     factory(School::class,1) 
      ->create(['SchoolId' => 1, 'CompanyId' => 1]); 
     factory(Mentor::class,1) 
      ->create(['MentorId' => 1, 'SchoolId' => 1, 'CompanyId' => 1]); 
     factory(Department::class,1) 
      ->create(['DepartmentId' => 1,'CompanyId' => 1]); 
     factory(Intern::class,1) 
      ->create(['InternId' => 1, 'MentorId' => 1]); 
     factory(Employee::class,1) 
      ->create(['EmployeeId' => 1, 'RoleId' => 1, 'DepartmentId' => 1, 'InternId' => 1, ]); 


     $client = new Client(); 
     $res = $client->request('POST', $this->url.'/api/v1/school/1',[ 
      'form_params' => [ 
       'currentUserId' => 1 
      ] 
     ]); 
     $this->assertEquals(200, $res->getStatusCode()); 
    } 

這將返回狀態碼500.但是，當我刪除use DatabaseTransaction它的工作！？在我的config/database.php中，我已將默認設置設置爲測試連接'default' => env('DB_CONNECTION', 'mysql_testing'),有人可以告訴我我做錯了什麼。

use DatabaseTransactions;
