@michapietsch I have this issue as well. Did you make an upgrade from previous version to 5.7 too? Fresh installation of Laravel 5.7 works just fine on Artisan::output()

[kevinp1005]

Update on the issue , something to do with laravel/telescope

If you have it installed, you can disable the watcher in config/telescope.php

[sarfraznawaz2005]

Should be some other solution like priority/etc instead of disabling it completely in Telescope.

[kevinp1005]

@sarfraznawaz2005 I think in this case we need to choose either one of them, since both telescope and Artisan::output uses symfony's console BufferedOutput which empties the buffer. And so it makes it has first come first serve behaviour.

Closing this as the explanation has been given in the linked issue.

Yes, set telescope config:

    Watchers\CommandWatcher::class => [
        'enabled' => env('TELESCOPE_COMMAND_WATCHER', true),
        'ignore' => ['migrate', 'migrate:status'] //etc
    ],

Just in case someone will google for words Artisan::output() is empty during tests in Laravel 5.7 or Laravel 5.8:

Here is the solution, use
public $mockConsoleOutput = false; in your TestCase class.
this is something introduced in Laravel 5.7, but never documented

In your \Illuminate\Console\Command subclass, you should write your output using "$this->line()" or other similar methods, then you could get your output using "Artisan::output()".
