反射异常类文件系统不存在

Question

我正在为使用 Laravel 5 中的 Storage 外观的类创建测试。运行测试时出现错误“ReflectionException: Class filesystem does not exist”。

这是测试代码

use Illuminate\Foundation\Testing\WithoutMiddleware;
use Illuminate\Foundation\Testing\DatabaseMigrations;
use Illuminate\Foundation\Testing\DatabaseTransactions;

use Illuminate\Support\Facades\Storage as Storage;
use App\Fourpoint\services\Material;

use \Illuminate\Container\Container as Container;
use \Illuminate\Support\Facades\Facade as Facade;

class MaterialServiceTest extends TestCase
{
use DatabaseMigrations;

protected $directory;
protected $file;

public function setUp(){

    $app = new Container();
    $app->singleton('app', 'Illuminate\Container\Container');

    Facade::setFacadeApplication($app);

    $this -> mat = new \App\FourPoint\services\Material();
    $this -> directory = 'home/Code/project4point/tests/mockFiles';

    $this -> file = new \Symfony\Component\HttpFoundation\File\UploadedFile('tests/mockFiles/testPDF.pdf', 'testPDF.pdf');

}

public function testNewMaterial(){

    Storage::shouldReceive('put')
        ->andReturn(true);

    Storage::shouldReceive('exists')
        ->andReturn(true);

    $this -> mat->newMaterial('pdf',1,1,'testPDF',$this -> file,1,1);

}
}

错误是由“Storage::shouldReceive('put')”引起的

Answer 1

这是因为您的类从 testCase 扩展而来，该类已经有自己的应该运行的方法“setUp”。当您在子类中定义方法“setUp”时，您会覆盖父类的方法。

解决方法：先这样调用父类方法

public function setUp(){
    parent::setUp();
    ... your own setup
}

Answer 2

您可以将函数修改为：

public function testNewMaterial()
{
   $storage = $this->mockStorage();

   $storage->shouldReceive('put')->andReturn(true);

   $storage->shouldReceive('exists')->andReturn(true);

   $this->mat->newMaterial('pdf',1,1,'testPDF',$this -> file,1,1);

}

protected function mockStorage()
{
    Storage::extend('mock', function() {
        return \Mockery::mock(\Illuminate\Contracts\Filesystem\Filesystem::class);
    });

    Config::set('filesystems.disks.mock', ['driver' => 'mock']);
    Config::set('filesystems.default', 'mock');

    return Storage::disk();
}
