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!

  ->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

.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')
    ])
