How to test file upload with laravel and phpunit?
提问by Jasper Kennis
I'm trying to run this functional test on my laravel controller. I would like to test image processing, but to do so I want to fake image uploading. How do I do this? I found a few examples online but none seem to work for me. Here's what I have:
我正在尝试在我的 Laravel 控制器上运行此功能测试。我想测试图像处理，但为此我想伪造图像上传。我该怎么做呢？我在网上找到了一些例子，但似乎没有一个对我有用。这是我所拥有的：
public function testResizeMethod()
{
$this->prepareCleanDB();
$this->_createAccessableCompany();
$local_file = __DIR__ . '/test-files/large-avatar.jpg';
$uploadedFile = new Symfony\Component\HttpFoundation\File\UploadedFile(
$local_file,
'large-avatar.jpg',
'image/jpeg',
null,
null,
true
);
$values = array(
'company_id' => $this->company->id
);
$response = $this->action(
'POST',
'FileStorageController@store',
$values,
['file' => $uploadedFile]
);
$readable_response = $this->getReadableResponseObject($response);
}
But the controller doesn't get passed this check:
但是控制器没有通过这个检查：
elseif (!Input::hasFile('file'))
{
return Response::error('No file uploaded');
}
So somehow the file isn't passed correctly. How do I go about this?
所以不知何故文件没有正确传递。我该怎么做？

Docs for CrawlerTrait.html#method_actionreads:
CrawlerTrait.html#method_action 的文档如下：
Parameters
string $method
string $action
array $wildcards
array $parameters
array $cookies
array $files
array $server
string $content
参数
字符串 $method
字符串 $action
数组 $wildcards
数组 $parameters
数组 $cookies
数组 $files
数组 $server
字符串 $content
So I assume the correct call should be
所以我认为正确的调用应该是
$response = $this->action(
'POST',
'FileStorageController@store',
[],
$values,
[],
['file' => $uploadedFile]
);
unless it requires non-empty wildcards and cookies.
除非它需要非空的通配符和 cookie。

For anyone else stumbling upon this question, you can nowadays do this:
对于任何在这个问题上绊倒的人，你现在可以这样做：
$response = $this->postJson('/product-import', [
'file' => new \Illuminate\Http\UploadedFile(resource_path('test-files/large-avatar.jpg'), 'large-avatar.jpg', null, null, null, true),
]);

With phpunit you can attach a file to a form by using attach() method.
使用 phpunit，您可以使用 attach() 方法将文件附加到表单。
Example from lumen docs:
流明文档中的示例：
public function testPhotoCanBeUploaded()
{
$this->visit('/upload')
->name('File Name', 'name')
->attach($absolutePathToFile, 'photo')
->press('Upload')
->see('Upload Successful!');
}

Here is a full example how to test with custom files. I needed this for parsing CSV files with known format so my files had to had exact formatting and contents. If you need just images or random sized files use $file->fake->image() or create() methods. Those come bundled with Laravel.
这是如何使用自定义文件进行测试的完整示例。我需要它来解析已知格式的 CSV 文件，因此我的文件必须具有精确的格式和内容。如果您只需要图像或随机大小的文件，请使用 $file->fake->image() 或 create() 方法。那些与 Laravel 捆绑在一起。
namespace Tests\Feature;
use Tests\TestCase;
use Illuminate\Http\UploadedFile;
use Illuminate\Support\Facades\Storage;
class PanelistImportTest extends TestCase
{
/** @test */
public function user_should_be_able_to_upload_csv_file()
{
// If your route requires authenticated user
$user = Factory('App\User')->create();
$this->actingAs($user);
// Fake any disk here
Storage::fake('local');
$filePath='/tmp/randomstring.csv';
// Create file
file_put_contents($filePath, "HeaderA,HeaderB,HeaderC\n");
$this->postJson('/upload', [
'file' => new UploadedFile($filePath,'test.csv', null, null, null, true),
])->assertStatus(200);
Storage::disk('local')->assertExists('test.csv');
}
}
Here is the controller to go with it:
这是与之配套的控制器：
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Storage;
class UploadController extends Controller
{
public function save(Request $request)
{
$file = $request->file('file');
Storage::disk('local')->putFileAs('', $file, $file->getClientOriginalName());
return response([
'message' => 'uploaded'
], 200);
}
}

The best and Easiest way :First Import the Necessary things
最好最简单的方法：首先导入必要的东西
use Illuminate\Http\UploadedFile;
use Illuminate\Support\Facades\Storage;
Then make a fake file to upload.
然后制作一个假文件上传。
Storage::fake('local');
$file = UploadedFile::fake()->create('file.pdf');
Then make a JSON Data to pass the file. Example
然后制作一个 JSON 数据来传递文件。例子
$parameters =[
'institute'=>'Allen Peter Institute',
'total_marks'=>'100',
'aggregate_marks'=>'78',
'percentage'=>'78',
'year'=>'2002',
'qualification_document'=>$file,
];
Then send the Data to your API.
然后将数据发送到您的 API。
$user = User::where('email','[email protected]')->first();
$response = $this->json('post', 'api/user', $parameters, $this->headers($user));
$response->assertStatus(200);
I hope it will work.
我希望它会起作用。

Add similar setUp()method into your testcase:
将类似的setUp()方法添加到您的测试用例中：
protected function setUp()
{
parent::setUp();
$_FILES = array(
'image' => array(
'name' => 'test.jpg',
'tmp_name' => __DIR__ . '/_files/phpunit-test.jpg',
'type' => 'image/jpeg',
'size' => 499,
'error' => 0
)
);
}
This will spoof your $_FILES global and let Laravel think that there is something uploaded.
这会欺骗你的 $_FILES 全局变量，让 Laravel 认为有东西上传了。
