Laravel artisan命令测试输出“+----+----------+------------+----------------------+&引用；没有印刷

我正在尝试测试artisan命令，该命令将给定客户id的db表作为输出。 在拉威尔8号

php artisan get:report "1"
+----+----------+------------+---------------------+
| id | customer | date       | value               |
+----+----------+------------+---------------------+
| 1  | 1        | 01/04/2015 | EUR 55.201818920353 |
| 5  | 1        | 02/04/2015 | EUR 12.188561617614 |
| 6  | 1        | 02/04/2015 | EUR 1.00            |
| 7  | 1        | 03/04/2015 | EUR 14.050917779273 |
+----+----------+------------+---------------------+

所以我写了这个单元测试：

<?php

namespace Tests\Unit;

use Tests\TestCase;
use Illuminate\Foundation\Testing\RefreshDatabase;


class GetReportTest extends TestCase
{
    
    protected $tableHeader=['id', 'customer', 'date','value'];
    protected $rows=[[1,'1','01/04/2015' , 'EUR 55.201818920353'],
                        [5,'1' ,'02/04/2015',' EUR 12.188561617614'],
                        [6,'1','02/04/2015','EUR 1.00' ],
                        [7,'1','03/04/2015','EUR 14.050917779273' ]  ];
  
    
     /** @test */
    public function getReportCommand()
    {
        $this->assertTrue(class_exists(\App\Console\Commands\GetClientReport::class));
    }
    
    /** @test */
    public function itCanGetReport()
    {
        $this->artisan('get:report "1"')->expectsTable($this->tableHeader,$this->rows)
        ->assertExitCode(0);
        $this->assertTrue(true);


    }
    
  
}

我的问题是： 如何与命令输出交互？ 这是执行此类测试的正确方法吗？ 我是否需要一个函数来测试每个可能的输入

⨯ it can get report
