如何用laravel和phpunit测试文件上传 - How to test file upload with laravel and phpunit?

我试图在我的laravel控制器上运行这个功能测试。我想测试图像处理，但要这样做，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，但似乎没有一个适合我。我有:

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);
}

但是控制器没有通过这个检查:

elseif (!Input::hasFile('file'))
{
    return Response::error('No file uploaded');
}

所以不知何故，文件没有正确传递。我该怎么做呢?

对于遇到这个问题的人，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),
    ]);

更新

在Laravel 6中，'Illuminate'Http'UploadedFile类的构造函数有5个参数而不是6个。这是新的构造函数:

    /**
     * @param string      $path         The full temporary path to the file
     * @param string      $originalName The original file name of the uploaded file
     * @param string|null $mimeType     The type of the file as provided by PHP; null defaults to application/octet-stream
     * @param int|null    $error        The error constant of the upload (one of PHP's UPLOAD_ERR_XXX constants); null defaults to UPLOAD_ERR_OK
     * @param bool        $test         Whether the test mode is active
     *                                  Local files are used in test mode hence the code should not enforce HTTP uploads
     *
     * @throws FileException         If file_uploads is disabled
     * @throws FileNotFoundException If the file does not exist
     */
    public function __construct(string $path, string $originalName, string $mimeType = null, int $error = null, $test = false)
    {
        // ...
    }

所以上面的解决方案变得简单:

$response = $this->postJson('/product-import', [
        'file' => new 'Illuminate'Http'UploadedFile(resource_path('test-files/large-avatar.jpg'), 'large-avatar.jpg', null, null, true),
    ]);

Docs for CrawlerTrait.html#method_action reads:

参数字符串$方法
字符串$行动
数组$通配符
参数数组$
数组$饼干
数组$文件
数组$服务器
字符串$content

所以我认为正确的调用应该是

$response = $this->action(
    'POST',
    'FileStorageController@store',
    [],
    $values,
    [],
    ['file' => $uploadedFile]
);

最好和最简单的方法:首先导入必要的东西

use Illuminate'Http'UploadedFile;
use Illuminate'Support'Facades'Storage;

然后制作一个假文件上传。

Storage::fake('local');
$file = UploadedFile::fake()->create('file.pdf');

然后制作一个JSON Data来传递文件。示例

$parameters =[
            'institute'=>'Allen Peter Institute',
            'total_marks'=>'100',
            'aggregate_marks'=>'78',
            'percentage'=>'78',
            'year'=>'2002',
            'qualification_document'=>$file,
        ];

然后将数据发送到您的API。

$user = User::where('email','candidate@fakemail.com')->first();
$response = $this->json('post', 'api/user', $parameters, $this->headers($user));
$response->assertStatus(200);

使用phpunit，您可以使用attach()方法将文件附加到表单上。

示例来自lumen docs:

public function testPhotoCanBeUploaded()
{
    $this->visit('/upload')
         ->name('File Name', 'name')
         ->attach($absolutePathToFile, 'photo')
         ->press('Upload')
         ->see('Upload Successful!');
}

下面是一个如何使用自定义文件进行测试的完整示例。我需要它来解析具有已知格式的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。这些都是与Laravel捆绑的。

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');
    }
}

下面是控制器:

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);
    }
}

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
        )
    );
}

这将欺骗你的$_FILES全局，让Laravel认为有东西上传。
