在laravel中测试多存储

我在尝试模拟multi时遇到问题 Storage 在laravel测试环境中。

这是我的密码:

public function sftp ( Sibling $sibling ) {
        $file_paths = Storage::build($sibling->config)
                             ->files($this->track->track_token);
        Storage::disk('public')
               ->makeDirectory($this->track->track_token);
        foreach ( $file_paths as $file_path ) {
            $file_content = Storage::build($sibling->config)
                                   ->get($file_path);
            TrackMp3::query()
                    ->where('track_id' , $this->track->id)
                    ->where('file_name' , basename($file_path))
                    ->update([
                                 'downloaded_at' => now() ,
                             ]);
            Storage::disk('public')
                   ->put($file_path , $file_content);
        }
    }

这是我的测试用例:

public function test_sftp_works_when_track_exists_in_sibling () {
        $track_token = md5('sample');
        $track_320 = UploadedFile::fake()
                                 ->create('track_320.mp3')
                                 ->getContent();
        $track_160 = UploadedFile::fake()
                                 ->create('track_160.mp3')
                                 ->getContent();
        $track_96 = UploadedFile::fake()
                                ->create('track_96.mp3')
                                ->getContent();
        $track_demo = UploadedFile::fake()
                                  ->create('track_demo.mp3')
                                  ->getContent();
        $sibling = SiblingFactory::new()
                                 ->create();
        $public_disk = Storage::fake('public');
        $sibling_disk = Storage::fake('sibling');
        Storage::shouldReceive('build')
               ->with($sibling->config)
               ->andReturn($sibling_disk);
        $sibling_disk->put($track_token . '/track_320.mp3' , $track_320);
        $sibling_disk->put($track_token . '/track_160.mp3' , $track_160);
        $sibling_disk->put($track_token . '/track_96.mp3' , $track_96);
        $sibling_disk->put($track_token . '/track_demo.mp3' , $track_demo);
        $track = TrackFactory::new()
                             ->md5Fetched()
                             ->has(TrackMp3Factory::new([ 'md5' => md5_file($sibling_disk->path($track_token . '/track_320.mp3')) ])
                                                  ->fileName320())
                             ->has(TrackMp3Factory::new([ 'md5' => md5_file($sibling_disk->path($track_token . '/track_160.mp3')) ])
                                                  ->fileName160())
                             ->has(TrackMp3Factory::new([ 'md5' => md5_file($sibling_disk->path($track_token . '/track_96.mp3')) ])
                                                  ->fileName96())
                             ->has(TrackMp3Factory::new([ 'md5' => md5_file($sibling_disk->path($track_token . '/track_demo.mp3')) ])
                                                  ->fileNameDemo())
                             ->create([ 'track_token' => $track_token ]);

        Storage::fake('public'); // ----> Error happend here
        Artisan::call('download');
    }

以下是错误:
