I am testing that a file is remove after a response download as below:

UploadedFile::fake()
    ->create('test-file.xlsx')
    ->storeAs("{$dataset->id}", 'test-excel-file.xlsx'.,'datasets');

$this->get(route('datasets.export', ['dataset' => $dataset->id, 'hash' => 'test-excel-file']))
    ->assertHeader('Content-Type', 'excel.mime'))
    ->assertHeader('Content-Disposition', "attachment; filename=downloadFileName");

Storage::disk('datasets')->assertMissing("{$dataset->id}/test-excel-file.xlsx");

the code for the response is the following:

    return response()->download(
        $dataset->filePath(),
        'downloadFileName',
        [
            'Content-Type' => 'excel.mime',
            'Cache-Control' => 'cache, must-revalidate',
        ]
    )->deleteFileAfterSend(true);

i am getting this error:

Tests\Feature\SendExportGeneratedEmailTest::it_downloads_the_dataset_file
Found unexpected file at path [1/test-excel-file.xlsx].
Failed asserting that true is false.

Every assertion works except the assertMissing. The file is not being deleted, but when tested in the browser it works

hope anyone can help
