是否可以使用Laravels Storage::fake()
方法来模拟文件?
我已将https://laravel.com/docs/5.7/mocking#storage-fake用作测试的基础,可以很好地用于上传。但是我的下载测试很丑陋,因为我每次都要使用模拟上传UploadedFile::fake()->image('avatar.jpg')
首先运行我的上传路由。有没有办法跳过该部分并模拟文件直接存在于假存储系统中?
public function testAvatarUpload()
{
Storage::fake('avatars');
// This is the call I would like to change into a mocked existing uploaded file
$uploadResponse = $this->json('POST', '/avatar', [
'avatar' => UploadedFile::fake()->image('avatar.jpg')
]);
// Download the first avatar
$response = $this->get('/download/avatar/1');
$response->assertStatus(200);
}

我可能在这里迟到了。但希望帮助其他访问此问题的人给出实现该问题的想法。
这里是带有一些断言的示例。
<?php
namespace Tests\Feature\Upload;
use Illuminate\Http\File;
use Illuminate\Support\Facades\Storage;
use Tests\TestCase;
class SampleDownloadTest extends TestCase
{
/**
* @test
*/
public function uploaded_file_downloads_correctly()
{
//keep a sample file inside projectroot/resources/files folder
//create a file from it
$exampleFile = new File(resource_path('files/test-file.png'))
//copy that file to projectroot/storage/app/uploads folder
Storage::putFileAs('/uploads', $exampleFile, 'test-file.png');
//make request to file download url to get file
$response = $this->get("/files/file/download/url");
//check whethe response was ok
$response->assertOk();
$response->assertHeader('Content-Type', 'image/png')
//check whether file exists in path
Storage::assertExists('/uploads/test-file.png');
//do some more assertions.....
//after test delete the file from storage path
Storage::delete('uploads/test-file.png');
//check whether file was deleted
Storage::assertMissing('/uploads/test-file.png');
}
}

您可以直接直接创建一个新文件,也可以复制特定的测试文件,例如:
use Illuminate\Http\File;
use Illuminate\Support\Facades\Storage;
// for simple text files or if the content doesn't matter
Storage::disk('avatars')->put('avatar.jpg', 'some non-jpg content');
// if you need a specific file for your test
$file = new File(base_path('tests/resources/avatar.jpg'));
Storage::disk('avatars')->putFileAs('/', $file, 'avatar.jpg');
后一个函数将使用$file
并将其以给定名称avatar.jpg
复制到磁盘/
上的给定目录avatars
。您可以详细了解in the official documentation。

您可以用来解决该问题的是灯具。 Laravel的测试框架实质上是PHPUnit,所以我看不出为什么它不起作用。
这样定义测试:
use Tests\TestCase;
class ExampleTest extends TestCase {
protected function setUp() {
parent::setUp();
Storage::fake('avatars');
$uploadResponse = $this->json('POST', '/avatar', [
'avatar' => UploadedFile::fake()->image('avatar.jpg')
]);
}
protected function tearDown() {
parent::tearDown();
}
public function testAvatarUpload() {
// Download the first avatar
$response = $this->get('/download/avatar/1');
$response->assertStatus(200);
}
}
在课程中的每个测试之前和之后,分别调用 setUp
和tearDown
。因此,在每种测试方法之前,setUp
将擦除avatars
伪磁盘并运行请求。由于测试后无事可做(因为Storage::fake()
替换了磁盘,如果该磁盘已经存在),则该方法为空;我把它留在这里纯粹是为了使示例更完整。
关于PHPunit的此功能,有一些相当不错的文档on here。
关于将文件放置在此处,一旦setUp
正常工作,就没有什么可以阻止您将文件扔在上面。

是的,你可以使用 Laravel 的假文件存储功能(mocking):
use Illuminate\Http\UploadedFile;
$file = UploadedFile::fake()->create('filename.ext', $sizeInKb)->store('filename.ext');
如果您想创建具有特定内容的文本/csv文件,您可以使用:
use Illuminate\Http\UploadedFile;
$header = 'a,b,c';
$row1 = 'x,y,z';
$row2 = 's,f,t';
$row3 = 'r,i,o';
$content = implode("\n", [$header, $row1, $row2, $row3]);
$file = UploadedFile::fake()->createWithContent('filename.ext', $content)->store('filename.ext');
您可以在 Illuminate\Http\Testing\FileFactory
