Run the following:

composer require sandyandi/test-uploadedfile-factory:1.0.*

use Sandyandi\TestUploadedFileFactory\TestUploadedFileFactory;

$testUploadedFileFactory = new TestUploadedFileFactory;

By default, it will use the /tmp directory located in vendor/sandyandi/test-uploadedfile-factory as its working directory. You can specify a different directory by specifying the directory path during instantiation:

$workDir = 'path/to/your/work/dir';
$testUploadedFileFactory = new TestUploadedFileFactory($workDir);

Note: make sure the working directory is writeable.

Once the factory has been instantiated, you can create an UploadedFile instance by doing the following:

$pathToFile = 'path/to/your/file';
$uploadedFile = $testUploadedFileFactory->create($pathTofile);

The factory will create a copy of your file and put it in the working directory.

Be sure to call $testUploadedFileFactory->tearDown(); in your test's tearDown() method to delete all created/moved files.
