存储中的模拟文件以在 Laravel 中下载

Question

有没有办法使用 LaravelStorage::fake()方法模拟文件？

我已经使用https://laravel.com/docs/5.7/mocking#storage-fake作为我测试的基础，它适用于上传。但是我的下载测试很难看，因为我每次都必须先使用模拟上传运行我的上传路线UploadedFile::fake()->image('avatar.jpg')。有没有办法跳过那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);
}

我可能来晚了。但想帮助访问此问题的其他人提供实施它的想法。

这是一个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');
    }
}

是的，你可以使用 Laravel 的假文件存储功能（嘲笑）：

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，您可以使用以下命令：

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');
