存储中的模拟文件可在Laravel中下载

问题描述 投票:0回答:3

有没有办法使用Laravel Storage::fake()方法模拟文件?

我使用https://laravel.com/docs/5.7/mocking#storage-fake作为我测试的基础,适用于上传。但是我的下载测试很难看,因为我必须先使用模拟上传UploadedFile::fake()->image('avatar.jpg')来运行我的上传路由。有没有办法跳过该部分并模拟文件直接存在于虚假存储系统中?

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);
}

我可能会迟到。但是想帮助其他人访问这个问题来提出实现它的想法。

这是一个包含一些断言的示例。

<?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');
    }
}

您可以直接创建新文件或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');

后一个函数将获取$file并将其以给定名称avatar.jpg复制到磁盘/上的给定目录avatars。你可以阅读更多关于它in the official documentation

你可以用来解决这个问题的是固定装置。 Laravel的测试框架本质上是PHPUnit,所以我认为没有理由说它不起作用。

像这样定义你的测试:

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);
    }
}

setUptearDown分别在课堂上的每次测试之前和之后被调用。因此,在每种测试方法之前,setUp将擦除avatars假磁盘并运行请求。由于测试后无事可做(因为Storage::fake()替换了磁盘,如果它已经存在),该方法为空;我把它留在这里纯粹是为了让这个例子完整。

关于PHPunit的这个功能,有一些非常好的文档on here

关于把文件放在那里,一旦你的setUp正常工作,没有什么能阻止你把文件扔到它上面。
