如何使用Mockery和PHPUnit

Question

我正在使用PHPUnit来测试我的API，但我不确定如何测试文件上传。

我看了this Laracast lesson，这让我很好地了解了如何使用Mockery模拟上传，但在我的情况下，我正在尝试测试API，无论出于何种原因，我都无法获得我对格林的考验。

我的测试代码：

namespace App;

use Symfony\Component\HttpFoundation\File\UploadedFile;
use Mockery as m;

class ApiResourcesControllerTest extends \TestCase
{
    /** @test */
    function a_user_can_upload_a_resource()
    {
        $file = m::mock(UploadedFile::class, [
            'getClientOriginalName' => 'test.jpg'
        ]);

        $file->shouldReceive('move') // the uploaded file is moved 
             ->once()
             ->with('uploads', 'now-test.jpg');

        $files = ['file' => $file]; // endpoint expects Input::file('file);

        // this endpoint definitely works
        $this->call('POST', 'api/resources/upload', [], [], $files);
        $this->dump(); // for the mean time just dump the response
    }
}

function time()
{
    return 'now';
}

我知道api/resources/upload端点工作正常，但我的测试代码返回以下错误：

Mockery\Exception\InvalidCountException: Method move("uploads", "now-test.jpg") from Mockery_0_Symfony_Component_HttpFoundation_File_UploadedFile should be called exactly 1 times but called 0 times.

我哪里错了？

非常感谢模拟文件上传到API的示例。
