Laravel 无法使用模拟服务和对象测试作业。 Mockery 间谍无法检测到被调用的方法

Question

我想测试我的工作的功能：

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();
        }
    }
}

我想用纯单元测试来测试它：

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();
    }
}

但是一旦我通过以下方式测试它：

./vendor/bin/phpunit ./test/Jobs/TestJob.php

我得到以下输出：

PHPUnit 7.5.20 by Sebastian Bergmann and contributors.

E                                                                   1 / 1 (100%)

你知道为什么spy没有检测到method方法的调用吗？

Answer 1

你错误地调用了shouldHaveReceived的嘲弄。

使用这种方法：

$mockedNewsLetterService->shouldHaveReceived(`method`)->with($model);

另外，为了测试作业调度，我使用了app的bindMethod ，因此测试应该是：

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);

    $this->app->bindMethod(NewsLetterSubscribeUserJob::class.'@handle', function ($job, $app) use ($mockedNewsLetterService){
        return $job->handle($mockedNewsLetterService);
    });

    MyJob::dispatchNow($model);
    $mockedNewsLetterService->shouldHaveReceived('method')->with($model);
}

如您所见，我使用该应用程序来处理作业调度。 同样为了在测试期间避免 3rd 方服务，我也使用dispatchNow以免我的工作排队。
