Test FileUpload

I can't test my FileUpload I have this test: 
Livewire::actingAs($user)
  ->test(FormForm::class, [
      'formType' => FormType::DFD,
      'userForm' => $form,
      'operation' => 'create',
  ])
  ->set('data', [
      'name' => 'Test',
      // 'file' => UploadedFile::fake()->create('file.pdf', 100, 'application/pdf')
    ])
  ->call('createOrEdit');
Livewire::actingAs($user)
  ->test(FormForm::class, [
      'formType' => FormType::DFD,
      'userForm' => $form,
      'operation' => 'create',
  ])
  ->set('data', [
      'name' => 'Test',
      // 'file' => UploadedFile::fake()->create('file.pdf', 100, 'application/pdf')
    ])
  ->call('createOrEdit');
This test PASSES. If I uncomment the line 
'file' => UploadedFile::fake()->create('file.pdf', 100, 'application/pdf')
'file' => UploadedFile::fake()->create('file.pdf', 100, 'application/pdf')
the test fails on line 
->call('createOrEdit')
->call('createOrEdit')
with the following error:

I tried all the solutions I could find online, without success...
Solution:
I found the solution! ```php ->set('data.name', 'Test') ->set('data.file.0' => UploadedFile::fake()->create('file.pdf', 100, 'application/pdf'))...

I think you have to somehow persist the fake() to the livewire-tmp directory. UploadedFile doesn’t return an instance of TemporaryFileUpload, so it doesn’t know how to handle it. Probably need to fake the Storage too.

I found the solution! 
  ->set('data.name', 'Test')
  ->set('data.file.0' => UploadedFile::fake()->create('file.pdf', 100, 'application/pdf'))
  ->set('data.name', 'Test')
  ->set('data.file.0' => UploadedFile::fake()->create('file.pdf', 100, 'application/pdf'))
I got it from a Dan Harrin's answer on github. You have to add .0 after the field name. Be careful, the following doesn't work: 
  ->set('data', [
      'name' => 'Test',
      'file.0' => UploadedFile::fake()->create('file.pdf', 100, 'application/pdf')
    ])
  ->set('data', [
      'name' => 'Test',
      'file.0' => UploadedFile::fake()->create('file.pdf', 100, 'application/pdf')
    ])
