Imagine you are using streamed downloads in your Laravel controllers like this:

1use App\Services\GitHub;
2
3return response()->streamDownload(function () {
4    echo GitHub::api('repo')
5                ->contents()
6                ->readme('laravel', 'laravel')['contents'];
7}, 'laravel-readme.md');

I was doing this in a project and I wanted to test it. I wanted to make sure that the response was streamed and that the content was correct.

The way I tested it was like this:

 1/** @test */
 2public function it_streams_the_download()
 3{
 4    $user = User::factory()->create();
 5
 6    $response = $this->actingAs($user)
 7        ->get('/my-endpoint')
 8        ->assertOk();
 9
10    $content = $response->streamedContent();
11    $this->assertEquals('The content of the file', $content);
12}

Thanks for this article for the inspiration.
