Failed console command output expectations

[DarkGhostHunter]

• Testbench Version: 6.19.0
• Laravel Version: 8.5.20
• PHP Version: 8.0.
• Database Driver & Version: SQLite 3

Description:

When testing commands created, output is never captured for assertion.

Steps To Reproduce:

1. Create a Console command

<?php

namespace MyVendor\MyPackage;

use Illuminate\Console\Command;

class DummyCommand extends Command
{
    /**
     * The name and signature of the console command.
     *
     * @var string
     */
    protected $signature = 'sample:command';

    /**
     * The console command description.
     *
     * @var string
     */
    protected $description = 'Sample command';

    /**
     * Execute the console command.
     *
     * @return int
     */
    public function handle(): int
    {
        $this->info('It works!');

        return 0;
    }
}

2. Register the command into the application. For convenience, we will use the same test.
3. Set output expectation.

<?php

namespace Tests\Console\Commands;

use Orchestra\Testbench\TestCase;
use MyVendor\MyPackage\DummyCommand;

class CommandTest extends TestCase
{
    public function setUp(): void
    {
        \Illuminate\Console\Application::starting(function ($artisan) {
            $artisan->resolveCommands([DummyCommand::class])
        }

        parent::setUp();
    }

    public function test_artisan_command(): void
    {
        $this->artisan('sample:command')
            ->expectsOutput('It works!');
            ->run();
    }
}

4. Test will fail.

Output "It works!" was not printed.

I was having the exact same issue now. I was able to solve it by removing the following from our phpunit config:

<env name="SHELL_VERBOSITY" value="-1" />
