我想測試我的工作功能：namespace App\Jobs;use Illuminate\Bus\Queueable;use Illuminate\Contracts\Queue\ShouldQueue;use Illuminate\Foundation\Bus\Dispatchable;use Illuminate\Queue\InteractsWithQueue;use App\Model\Model;use App\Services\Service;class MyJob implements ShouldQueue{    use Dispatchable;    use InteractsWithQueue;    use Queueable;    /**     * Undocumented variable     *     * @var User     */    private $model;    public function __construct(Model $model)    {        $this->model=$model;    }    public function handle(Service $service): void    {        if($this->model->shouldCallService){            $service->method();        }    }}我想用一個純單元測試來測試它：namespace Tests\Jobs;use Tests\TestCase;use Mockery;use App\Services\MyService;use App\Jobs\MyJob;use App\Model\MyModel;class TestJob extends TestCase{    public function testMethod()    {                $this->app->instance(MyModel::class,\Mockery::mock(MyModel::class,function($mock){            $mock->shouldReceive('save')->andReturn(true);        }));        $model=factory(MyModel::class)->create([            'shouldCallService'=>true,        ]);        $mockedNewsLetterService=Mockery::spy(MyService::class);        $mockedNewsLetterService->shouldReceive('method')->once();        $job=new MyJob($model);        $job->handle($mockedNewsLetterService);        $mockedNewsLetterService->shouldHaveReceived()->method()->with($model);    }    public function tearDown() {        parent::tearDown();        Mockery::close();    }}但是一旦我通過以下方式測試它：./vendor/bin/phpunit ./test/Jobs/TestJob.php我得到以下輸出：PHPUnit 7.5.20 by Sebastian Bergmann and contributors.E                                                                   1 / 1 (100%)Time: 46.12 seconds, Memory: 34.00 MBThere was 1 error:ERRORS!Tests: 1, Assertions: 3, Errors: 1.你知道為什么間諜無法檢測到調用method方法嗎？
